of the manual are particularly important. If the instrument is operated without
reading the instructions, the instrument may not operate correctly.
WARNING
BEFORE CONNECTING POWER TO THE INSTRUMENT:
The protective earth terminals of this instrument must be connected to the protective conductor of the
mains power cord. The mains plug must only be inserted in a socket outlet provided with a protective
earth contact. This protection must not be negated by an extension power cord without a protective
grounding (earthing) conductor. Grounding one conductor of a two conductor outlet is not sufficient
protection.
Any interruption of the protective grounding conductor (inside or outside the instrument) or
disconnecting the protective earth terminal will cause a potential shock hazard that could result in
personal injury. Intentional interruption is prohibited.
if this instrument is to be energized via an autotransformer, make sure the common terminal is
connected to the neutral terminal (earthed pole) of the power source. For continued protection
against fire hazard, replace the line fuse only with a 250V fuse of the same current rating and specified
type (normal blow, time delay, etc.). DO NOT USE repaired fuses or short-circuited fuseholders to
replace blown fuses.
Whenever it is likely that the protection offered by grounding or fuses has been impaired, the
instrument must be made inoperative and be secured against any unintended operation.
Service instructions, and adjustment procedures requiring removal of the instrument top or bottom
covers, are for use by service-trained personnel only. To avoid dangerous electric shock, do not
perform any servicing or make any adjustments with the covers removed, unless qualified to do so.

LINE VOLTAGE SELECTION
BEFORE CONNECTING POWER TO THE INSTRUMENT, make sure that the fine voitage selector card
(in the rear panel power module) is set to the correct voltage level for the ac voltage being applied, and
that the correct fuse is installed. Refer to Section 11, Installation.
MAXIMUM INPUT SIGNAL POWER
TO PREVENT DAMAGE TO THE INSTRUMENT, make sure that signals applied to the input do not
exceed the input damage level specified for the instrument. Refer to Section 1, Specifications.
ELECTROSTATIC CHARGE
Electronic components and assemblies can be permanently degraded or damaged by electrostatic
discharge. Use the following precautions.
ENSURE that static-sensitive devices or assemblies are serviced at static-safe work stations providing
proper grounding for service personnel.
ENSURE that static-sensitive devices or assemblies are stored in static-shielding containers.
DO NOT wear clothing subject to static charge buildup, such as wool or synthetic materials.
DO NOT handle components or assemblies in carpeted areas.
DO NOT remove a component or assembly from its static-shielding protection until you are ready to
install it.
AVOID touching component leads, (Handle by the packaging only.)
NOTE
На 15kV static discharge source is brought near the vicinity of INPUT
1, there is the possibility of a static discharge to the center conductor
that could damage the input circuitry. Use “ESD caution” when
working in the vicinity of input 1 connector.

1-13. The instrument serial number is located in the upper right corner of the rear panel. The
serial number is in the form: 0000A00000. The first four digits and the letter are the serial number
prefix. The last five digits are the suffix. The prefix is the same for all identical instruments; it chan-
ges only when a change is made to the instrument. The suffix, however, is assigned sequentially
and is different for each instrument. The contents of this manual apply to instruments with the
serial number prefix(es) listed under SERIAL NUMBERS on the title page.
1-14. An instrument manufactured after the printing of this manual may have a serial number
prefix that is not listed on the title page. This unlisted serial number prefix indicates the instrument
is different from those described in this manual. The manual for this newer instrument is accom-
panied by a yellow "Manual Changes” supplement. This supplement contains change information
that explains how to adapt the manual to the newer instrument.
1-15, in addition to change information, the supplernent may contain information for correcting er-
rors in the manual. To keep this manual as current and accurate as possible, Hewlett-Packard recom-
mends that you periodically request the latest Manual Changes supplement. The supplement for this
manual is identified with the manual print date and part number, both of which appear on the
manual title page. Complimentary copies of the supplement are available from Hewlett-Packard.

1-17. DESCRIPTION
1-18. The HP 53508 is a CW microwave counter with a measurement range of 10 Hz to 20 GHz.
The HP 5351B and 53528 counters are similar to the 5350B, with the 5351B having an extended
measurement range of 10 Hz to 26.5 GHz, and the 5352B a range of 10 Hz to 40 GHz, All three
counters combine high performance microwave measurements with simple, easy-to-use operating
procedures. The HP 5350B/51B/52B is controlled by a single microprocessor which interacts with
the counting circuitry to generate data, compute and display measurements, and manipulate
measurement data.
1-19, Ali measurement modes and functions are selectable via 17 pushbutton keys on the front
panel. Selectable functions include Sample Rate and Resolution control for the various measure-
ments modes, and Math functions, such as Offset and Scale, for data manipulation. Additional
power and convenience are provided by user-callable test and diagnostic functions which can be
used for troubleshooting, and to obtain additional measurement information. The counter is
equipped with memory for saving the front panel setup when the counter is set to Standby mode.
All display functions are performed by a Liquid Crystal Display, which contains 24 alphanumeric
characters (including function annunciators) for displaying both messages and measurement data.
1-20. Full HP-1B programmability is a standard feature of the HP 5350B/51B/52B Microwave Fre-
quency Counter. The Hewlett-Packard interface Bus provides remote control of measurement func-
tions and data output. All front panel features are available via the HP-IB.

Before connecting the instrument to ac power lines, be sure that
the correct fuse is installed and that the voltage selector is
properly positioned as described below.
2-8. Line Voltage Selection
2-9. The instrument is equipped with an ac power module that contains a printed-circuit line
voltage selector to select 100-, 120-, 220-, or 240-volt ac operation. Before applying power, the
voltage selector must be set to the correct position and the correct fuse must be installed as
described below.
2-10. Power line connections are selected by the position of the plug-in circuit card in the
module. When the card is plugged into the module, the only visible marking on the card indicates
the line voltage to be used. The correct value of line fuse, with a 250 volt rating, must be installed
after the card is inserted. This instrument uses a 1.00 A time delay fuse (HP Part No. 2110-0007) for
100/120-volt operation, and a 0.5 A time delay fuse (HP Part No. 2110-0202) for 220/240-volt
operation,

2-16. Operating Environment
2-17. The instrument may be operated within the following environmental limits:
a. TEMPERATURE, The HP 5350B, 5351B and 5352B may be operated in temperatures from 0°C
to +50°C,
b. HUMIDITY. The HP 5350B, 5351B and 5352B may typically be operated in environments with
humidity up to 95% at 40°C. However, it should be protected from temperature extremes
which cause condensation within the instrument.
с. ALTITUDE. The HP 5350B, 5351B and 5352B may be typically operated at altitudes up to 4,600
metres {15,000 feet).
2-18. HEWLETT-PACKARD INTERFACE BUS
The above symbol when located in the upper corner of a page
indicates HP-IB information is contained on that page. This
information may be operation, performance, adjustment, or
service related.
2-19. HP-IB Interconnections
2-20. The HP 5350B/51B/52B is compatible with the Hewlett-Packard Interface Bus. Inter-
connection data concerning the rear panel HP-IB connector is provided in Figure 2-2. This
connector is compatible with the HP 10833A/B/C/D cables. (Refer to Table 2-2 for cable
descriptions.) The HP-IB system allows interconnection of up to 15 (including the controller) HP-
iB compatible instruments. The HP-IB cables have identical “piggy-back” connectors on both
ends so that several cables can be connected to a single source without special adapters or switch
boxes. System components and devices may be connected in virtually any configuration desired.
There must, of course, be a path from the controller to every device operating on the bus. Asa
practical matter, avoid stacking more than three or four cables on any one connector. If the stack
gets too large, the force on the stack produces leverage which can damage the connector
mounting. Be sure each connector is firmly (finger tight) screwed in place to keep it from working
loose during use. DO NOT use a screwdriver to tighten the connector lockscrew, as doing so may
damage the threads inside the head of the lockscrew.

2-21. Cable Length Restrictions
2-22. To achieve design performance with the HP-IB, the proper voltage levels and timing
relationships must be maintained. if the system cable is too long, the system will fail to perform
properly. Therefore, when interconnecting an HP-1B system, it is important to observe the
following rules:
a. The total cable length for the system must be less than or equal to 20 metres (65 feet).
b. Thetotal cable length for the system must be less than or equal to 2 metres (6.6 feet) times the
total number of devices connected to the bus.
с. The total number of instruments connected to the bus must not exceed 15.
2-23, HP-IB Talk/Listen Address
2-24. There are two ways to set the HP-1B instrument address for remote operation: setting the
rear panel address switch, and front panel keyboard entry. The rear panel switch setting
determines the mode of remote operation as “Talk Only” or “Addressable”, and selects the HP-IB
address. The HP-IB address can also be set by entering the address as numeric data via the front
panel keyboard, in which case the address set via the rear panel switch is overridden. The HP-IB
address entered via the keyboard will be retained by the counter as long as ac power is connected
to the instrument. Instructions for setting and changing the address are provided in Section Hl of
this manual.
2-25. HP-IB Descriptions
2-26. A description of the HP-1B is provided in Section Ill of this manual. A study of this
information is necessary if the user is not familiar with the HP-1B concept. Additional information
concerning the design criteria and operation of the bus is available in IEEE Standard 488-1978,
titled “IEEE Standard Digital Interface for Programmable Instrumentation.” Refer to Section IH for
a list of Hewlett-Packard manuals that provide additional background information on using HP-
iB. |
2-27. STORAGE AND SHIPMENT

3-4. OPERATING CHARACTERISTICS
3-5. The following paragraphs contain brief descriptions of the functions and characteristics of
the HP 5350B, 53518 and 53528. When discussing counter features and specifications, the
information given will always apply to all three models unless otherwise indicated, Refer to
paragraph 1-7 for a description of the terminology used in this manual to describe the three
models collectively and individually.
3-1
HP 5350B/53518/5352B
Operation and Programming
3-2
3-6. Overall Description
3-7. The HP 5350B is a CW microwave frequency counter with a measurement range of 10 Hz to
20 GHz. The HP 53518 and 53528 counters are similar to the 53508, with the 5351B having an
extended measurement range of 10 Hz to 26.5 GHz, and the 5352B a range of 10 Hz to 40 GHz.
Signals in the frequency range of 10 Hz to 80 MHz are measured by the direct count method, and
signals in the range of 10 MHz to 525 MHz are measured by the prescaled count method. Signals in
the frequency range of 500 MHz to MAX GHz are down-converted to an intermediate frequency
(IF) by HP's harmonic heterodyne down-conversion technique. The counted IF is added to, or
subtracted from, a multiple of the local oscillator (LO) frequency to determine the input
frequency.
3-8. The HP 5350B/51B/52B measures frequencies above 500 MHz with automatic amplitude
discrimination and user-selectable (normal or low) FM rate tolerance. Sample rate and resolution
are adjustable in steps via front panel controls. An internal microprocessor performs all
measurement calculations, taking into account the selected resolution, FM rate, and math
functions. Measurements are displayed in a fixed point format on the front panel! liquid crystal
display, with the segments to the right of the numeric portion of the display used to display
additional, alphanumeric information to the operator.
3-9. To maximize accuracy and resolution, the instruments IF counting circuitry uses a
reciprocal counting technique and analog interpolation. Since the HP 5350B/51B/52B uses the
reciprocal counting technique, it always makes a period measurement of the down-converted iF,
and then computes the IF using the reciprocal of the period measurement. Additional
measurement accuracy is obtained through the use of analog interpolators to reduce the inherent
one count uncertainty by compensating for time differences between the time base and input
trigger events,
3-10. The HP 5350B/51B/528 is a fully HP-1B (IEEE Standard 488-1978) programmable instrument,
capable of performing all operating functions via local or remote control. In addition to the basic
measurement function, the counter provides the following convenient features:
Math Functions (offset, scale, and smooth) give the user the capability of manipulating
measurement data. Refer to paragraphs 3-82, 3-84, and 3-85.
Diagnostics are available which perform various internal checks of the counter’s circuitry to
aid in service and troubleshooting. Auxiliary Functions (a subset of the diagnostic functions)
are also available for checking various measurement parameters, Refer to paragraphs 3-92,
3-96, 3-215, and to the diagnostic descriptions in Section VII
3-11. Operating Ranges
3-12. There are two basic operating ranges: 10 Hz to 525 MHz, and 500 MHz to MAX GHz,
Frequencies in the low range are measured directly or are prescaled, while frequencies in the
high range are measured using HP’s harmonic heterodyne down-conversion technique. Front
panel function keys allow the user to select INPUT 1for signals in the 500 MHz to MAX GHz range,
and INPUT 2 for signals in the 10 Hz to 525 MHz range. Two function keys allow the user to select
either AUTO or MANUAL measurement mode for INPUT 1 measurements. The low frequency
input has two impedance modes. Two function keys allow the user to select either 500 or IMO
input impedance for the INPUT 2 fused BNC connector.
3-13. Resolution
3-14. The best case resolution is the value represented by the least significant digit (LSD) in the
display. In the HP 5350B/51B/52B, a maximum resolution of 1 Hz can be selected using the
RESOLUTION key, together with the front panel INCREMENT and DECREMENT (arrow) keys,
HP 5350B/5351B/5352B
Operation and Programming
The displayed numerals of the measurement are grouped in four sections of three digits each for
ease in determining GHz, MHz, kHz, and Hz placement. Asterisks or blanks are used as piace
holders to improve interpretation of the display, depending on the resolution. For example, a
signal measured to 100 kHz resolution is displayed using asterisks, as shown below:
| kHz | Hz |
| СНЫ | MHZ
19 499 gx
- while a signal measured to 1 MHz resolution will be displayed using blanks, as shown
below:
GHz | MHZ | kHz | Hz |
1 490
3-15. When performing a low frequency, high impedance (INPUT 2, IMN) measurement, the
key labeled HIGH RESOL can be used to set a resolution greater than 1 Hz, up to .001 Hz. The
resolution obtained will depend on the input frequency.
3-16. Refer to paragraph 3-88 for information on using the RESOLUTION key, and to paragraph
3-98 for information on using the HIGH RESOL key.
3-17. Automatic Mode
3-18. The automatic mode of operation is selected by pressing the AUTO key. Input signais in
the 500 MHz-MAX GHz range are acquired, measured, and displayed automatically. When power
is initially turned on, the instrument goes into this mode automatically. Refer to paragraph 3-105
for a description of the Automatic measurement mode.
3-19. Manual Mode
3-20. The manual mode of operation is selected by pressing the MANUAL key. To operate in this
mode, input signals in the 1 GHz-MAX GHz range must be known to within 20 MHz (within 3 MHz
in the 500 MHz-1 GHz range), and this frequency {called the Manual Center Frequency) must be
specified prior to the measurement. After the MANUAL key has been pressed, the most recent
measurement becomes the Manual Center Frequency, or the operator may select a Center
Frequency by using the front panel entry keys. Refer to paragraphs 3-106 and 3-178 for detailed
information on using the Manual mode.
3-21. Sample Rate
3-22. The Sample Rate function sets the dead time between the end of one measurement and
the start of the next measurement. The duration of the measurement gate time is determined by
the resolution selected. The sample rate is adjustable in steps using the SAMPLE RATE key
together with the front panel INCREMENT and DECREMENT (arrow) keys. When the sample rate
is set to the minimum (FAST), the counter will measure as frequently as possible. The other
extreme (HOLD) will cause the counter to hold the last displayed measurement indefinitely, until
the TRIGGER key is pressed. Refer to paragraphs 3-95 and 3-188 for detailed information on
setting the sample rate.
3-23, FM Tolerance
3-24. The HP 5350B/518/52B will measure carrier frequencies which are modulated in
frequency, such as a microwave radio carrier. The FM tolerance specifies the worst case FM
Do deviations and rates which can be present without affecting the counter's ability to acquire the
Pr” signal. The counter averages out the deviations to measure the actual carrier frequency it can
tolerate, up to a maximum deviation of 20 MHz peak-to-peak {12 MHz peak-to-peak for the
HP 5350B/5351B/5352B
Operation and Programming
3-4
5352B |, at an FM rate equal to or greater than 1 kHz, when the counter is set for normal FM rate
tolerance.
3-25. FM Rate and Frequency Tracking
3-26. The HP 5350B/51B/52B is capable of measuring FM signals at various rates of deviation by
using the FM Rate/Track function. The FM RATE/TRACK key can be used to select Normal Rate,
Low Rate, or Track mode. Most measurements can be made with the counter set to Normal Rate
mode for signals with 1 kHz or greater rate of deviation. The Track mode uses a faster acquisition
time {with a corresponding loss of low FM rate tolerance) to increase the counter’s ability to track
signals with FM rates of 300 kHz or greater (for FM deviations up to the maximum specified in
Table 1-7). Conversely, the Low Rate mode uses a longer gate time for harmonic number
determination to allow measurements at FM rates as low as 45 Hz for the specified FM deviation.
Refer to Table 1-1 tor FM Rate/ Track and FM deviation specifications and to paragraphs 3-100 and
3-191 for information on using the FM Rate/Track function.
3-27. AM Tolerance
3-28. The HP 5350B/51B/52B is capable of measuring a signal with any modulation index as long
as the minimum signal level is greater than the sensitivity specification, and the maximum signal
level is less than the maximum operating level specification.
3-29. Automatic Amplitude Discrimination
3-30. The HP 5350B/51B/52B automatically acquires and displays the highest level signal within
its sensitivity range. The highest level signal must be at least 6 dB (typical) greater in amplitude
than any signal within 500 MHz, and 20 dB (typical) greater than any signal, within 500 MHz to
MAX GHz. This feature is useful for discriminating against spurious signals and harmonics.
3-31. Offset Frequencies
3-32. The Offset function allows the user to add or subtract a constant value to/from a frequency
measurement. For example, when measuring a radio IF and knowing the LO, the counter can be
set to display the RF input by entering the LO frequency as a positive offset. When tuning an
oscillator to a specific frequency, it may be easier to enter the desired frequency as a negative
offset and then tune the oscillator until the counter display reads zero. Offset frequencies are
entered using the OFFSET key together with front panel number keys, or the LST FRQ (Last
Frequency) key. Refer to paragraphs 3-82 and 3-194 for a detailed description of the Offset
Frequency function.
3- 33. Scale
3-34. The Scale function provides a means of multiplying the measured frequency by a scaling
factor selected on the keyboard. The scaling factor is set using the SCALE key together with front
panel number keys. When the factor is entered, the measured frequency is multiplied by this
factor, and the resulting product is displayed by the counter. The Scale function can also be used
together with the Offset Frequency function ((Fin X Scale) + Offset). Refer to paragraphs 3-84 and
3-197 for detailed information on using the Scale function.
3-35. Smooth
3-36. The Smooth function provides a means of “smoothing” the display for easier reading, and
is turned on or off by pressing the SMOOTH key. When the Smooth function is on, the counter
displays only the digits that are relatively stable, and keeps a running average of the
measurements to remove small deviations and increase displayed digits. Refer to paragraphs 3-85
and 3-199 for a detailed description of the Smooth function.
HP 5350B/5351B/5352B
Operation and Programming
3-37. Self Check
3-38. As a quick operation verification, the user may press the SELF CHECK key. Seif Check calls
up diagnostic subroutines to test the measurement circuitry. Refer to paragraphs 3-96 and 3-208
for detailed information on the Self Check function.
3-39. Diagnostics
3-40. In addition to the Self Check function, the HP 5350B/51B/52B has a variety of user-callable
diagnostic routines which perform various tests on the instrument for troubleshooting and
general information, The diagnostic mode is turned on by pressing the DIAGNOSTICS key, and a
particular diagnostic may be selected using the DIAGNOSTICS key together with front panel
number or arrow keys. Refer to paragraphs 3-92 and 3-204 for detailed information on using the
diagnostic functions.
3-41. Remote Operation
3-42. The HP-IB connector on the rear panel of the counter is compatible with the HP
10833A/B/C/D HP-IB cables, allowing the HP 5350B/51B/52B to be operated remotely within a
Hewlett-Packard Interface Bus system. In remote operation, all counter functions normally
available by front panel control (except POWER and STBY) are also available via HP-1B. The HP-IB
system allows interconnection of up to 15 HP-IB compatible instruments (including the
controller). The HP-1B connectors have identical “piggyback” connectors on both ends so that
several cables can be connected to a single source without special adapters or switch boxes.
System components and devices may be connected in virtually any configuration desired. Refer
to paragraph 2-19 for interconnection data concerning the HP 53508/51B/52B rear panel HP-IB
connector, and for restrictions on the Hewlett-Packard interface Bus connection,
3-43. Characteristics With Options Installed
3-44. The operating characteristics of the HP 5350B/51B/52B are affected by the addition of any
of the options described in the following paragraphs. Refer to Table 7-7 for all option
specifications.
3-45. Option 001 Oven Oscillator Timebase
3-46, With the addition of the Option 0091 Oven Oscillator, temperature and line voltage
variations are reduced, and short-term stability and aging rate are improved. Improved aging
allows extended calibration periods. The oven temperature is maintained when the HP
53508/518/528 POWER switch is in either the ON or STBY position (provided that ac power is
connected to the instrument). When the OVEN annunciator on the front panel display is lit, the
oscillator is warming. When the oven is at the proper temperature, the OVEN annunciator goes
out,
3-47. Option 002 Rear Panel Inputs
3-48. Option 002 provides rear panel inputs for both INPUT 1 and INPUT 2in place of the front
panel connectors on the 53508 and 5351B. The rear panel inputs are used for all the same
functional modes of operation as the front panel inputs. The specifications listed in Table 1-1 are
the same as for the front panel inputs, except for the sensitivity specifications listed under Option
002 Rear Panel Inputs. When equipped with Option 002, the HP 5350B INPUT 1 sensitivity is 1to 2
dB less than the standard instrument, and the HP 5351B INPUT 1 sensitivity is 1 to 3 dB less,
depending on frequency,

Operation and Programming
3-6
3-49. Option 006 Limiter
3-50. Option 006 provides additional input protection for the HP 5350B and 53518 by the
insertion of a limiter between the front panel high frequency connector (INPUT 1) and the input
circuitry. Option 006 increases the damage level specification of the instrument, as listed in Table
1-1 under Option 006 increased Damage Level. An HP 5350B/5351B equipped with Option 006 will
have its damage level increased by about 10 to 14 dB, depending on frequency.
3-51. Option 010 High Stability Timebase
3-52. The addition of the Option 010 High Stability Oven Oscillator improves the aging rate over
that of the Option 001 Oscillator, allowing further extended calibration periods of up to five years.
The oven temperature is maintained in exactly the same way as for the Option 001 Oscillator, and
the OVEN annunciator on the front panel display performs identically, lighting when the oven is
warming, and going out when the oven is at the proper temperature. |

OVERLOAD INDICATION FOR THIS PURPOSE.
3-56. Low Frequency input (INPUT 2)
3-57. The 10 Hz-525 MHz Low Frequency input BNC connector contains a fuse to provide
protection from input levels which exceed the specified damage level for INPUT 2: 5.5V rms (+28
dBm). Refer to paragraph 3-134 for instructions on how to change the front panel fuse.
TE
The INPUT 2 damage level described above is only a simplified
form of the complete specification. Refer to Table 1-1 for the
complete Damage Level specification for INPUT 2,
HP 53508/5351B/5352B
Operation and Programming
3-58. INPUT CABLE CONSIDERATIONS
ee 3-59. Consideration should be given to input cable losses at higher frequencies. For example, a
6-foot length of RG-214/U coaxial cable has about 15 dB loss at 18 GHz. Such losses must be taken
into consideration along with the sensitivity specifications given in Table 1-1.
3-60. INITIAL POWER-UP SELF TESTS AND DIAGNOSTICS
3-61. An automatic internal check (Power-Up Self Test) is made of several major components,
including the microprocessor and related circuitry, when the counter is powered-up. During the
power-up cycle, the display will first show all segments and annunciators lit, and then the current
HP-iB address. At the same time, the instrument proceeds through a set of diagnostic routines to
verify instrument operation, including both analog and digital circuit verification.
3-62. During the Power-Up Self Test cycle, the HP 5350B/51B/52B performs the following:
a. A front panel display routine is performed, during which all LCD segments and annunciators
are lit for about 3 seconds, allowing visual verification by the operator.
b. The microprocessor performs a RAM check, initializes the counter’s measurement circuitry,
initializes RAM, and then performs a ROM check.
с. À Self Test sequence is performed which verifies proper operation of the timebase oscillator,
the counting circuitry (including interpolators), tne LO and {IF circuitry, and the low
frequency input circuitry.
d. The HP-1B interface is checked, and the address is read from the rear panel switch and
displayed, (If the counter is powered-up from Standby, the last address entered via the front
panel keyboard is recalled.)
e. The current instrument status is checked, and the front panel annunciators are restored
accordingly. A check is made for the presence of an external reference, and for overload,
HOLD, and lockout conditions. The front panel annunciators are updated, if necessary.
f. The Diagnostic number is set to 1, diagnostic mode OFF, and the counter begins a
measurement,
3-63. If any of the tests during the Power-Up Self Test fail, a failure message will be displayed and
remain until the RESET/LOCAL key is pressed, causing the next test to be executed (if possible). In
this way, a failure may be bypassed to allow the counter to perform all of the power-up
diagnostics.
3-64. FRONT PANEL FEATURES
3-65. The front panel features of the HP 5350B/51B/52B are shown in Figure 3-2. General
information on the front panel keyboard begins at paragraph 3-66, and a complete description of
all the keys and their functions begins at paragraph 3-76. A detailed description of the front panel
display and annunciators begins at paragraph 3-109.
3-66. Keyboard
3-67. The front panel keyboard contains 17 push-button switches for inputting commands to
Pos the microprocesser. The keyboard is used for function selection and data entry. The keyboard
Ko switches consist of a RESET/LOCAL key, a SET/ENTER key, three MATH keys, and twelve
FUNCTION/DATA keys, as shown in Figure 3-2.
HP 53508/5351B/5352B
Operation and Programming
3-68. All keys on the keyboard, except RESET/LOCAL and SET/ENTER, play the dual roles of
function selection and parameter (data) entry. Function selection assignments are labeled above
each key on the front pane! and the data entry assignments are labeled to the left of each key.
Refer to Table 3-7 for a summary of all key assignments. With a few exceptions (shown in lower
case), the assignment names in the table are shown exactly the way they appear on the front
pane!

3-69. After pressing the SET/ENTER key and selecting a function which requires data entry, such
as OFFSET, the user is prompted by the display and the keyboard becomes a numeric entry pad.
Numeric entry is terminated by pressing the SET/ENTER key a second time. In the OFFSET mode,
entry of the last measurement as an offset is simplified by the LST FRQ key; this function sets the
frequency offset as the negative of the last measurement. The LST FRQ key can also be used to set
the manual center frequency to the last measurement.
3-70. Keyboard Memory
3-71. Whenever the instrument is set to Standby, the microprocessor automatically stores the
front panel settings, as long as the instrument is connected to an ac power source. When the
instrument is turned back on, it will be set to the last front panel settings. This avoids having to re-
enter math constants, functions or data, whenever the instrument is switched to Standby. If ac
power is applied to the counter just prior to turn-on, all function parameters will be initialized to
their power-up default values. Parameter value ranges and default values are shown in Table 3-2.

3-72. Entering Parameter Values
3-73. Parameter value entry is always initiated by pressing the SET/ENTER key once, and
terminated by pressing the SET/ENTER key a second time. When entering a parameter value, the
entire sequence may be aborted atany time by pressing the RESET/LOCAL key. The counter then
returns to the state it was in before the SET/ENTER key was pressed.
3-74. After the SET/ENTER key has been pressed once, the display shows “SET”, and the counter
waits for a function key to be pressed. After the SET/ENTER and the function key have been
pressed, the keyboard is in the “parameter entry mode”, and the data entry assignment of each
key is accessible. (Refer to Table 3-2.) The response to each key depends on the specific function
involved. The INC (increment) and DEC (decrement) keys will repeat if held down. The function
name appears in the right hand portion of the display during entry of the parameter value. Refer
to paragraph 3-162, Operating Procedures.
3-75. Certain parameter values, such as offset frequencies or scale factors, are entered as
numeric data, using the Function/Data keys. Other parameter values can be selected from a
specific range using the INC (increment) and DEC (decrement) keys, as with the Sample Rate and
Resolution parameters. Still other parameters are simply toggle functions, as for example the
Smooth or FM Rate Tolerance parameters, If the user should attempt to enter the incorrect type
of data as a parameter value, the counter will display either “PLEASE USE ARROW KEYS” or
“PLEASE USE DIGIT KEYS” to indicate the type of data entry required. If data entry is attempted
for a toggle function, the counter will display “TOGGLE FUNCTION ONLY".
3-76. Key Functions
3-77. The following paragraphs explain the primary function of each of the 17 keys in the front
panel keyboard. Three of the keys, OFFSET, SCALE, and SMOOTH, are grouped together in the
MATH section, and the remaining keys, except for RESET/LOCAL and SET/ENTER, are grouped
HP 5350B/5351B/5352B
Operation and Programming
3-10
together in the FUNCTION/DATA section. The location of each key is shown in Figure 3-2, Refer
to paragraph 3-162, Operating Procedures, for examples of how to use each of the major
functional modes of the HP 5350B/51B/52B.
3-78. POWER, When the POWER switch is in the ON position, power is
supplied to the entire instrument. The STBY (Standby) position removes
normal operating power to the instrument, but supplies power for
certain microprocessor and timebase circuits, as well as for the Option
001 and 010 oven oscillators to maintain a constant temperature for the
crystal. The STBY LED indicator located to the left of the POWER switch
will remain on when the switch is in the standby position. The input to
the power transformer, and dc voltages to the microprocessor standby
RAM, the timebase buffer, and the oscillator oven circuitry are always
energized whenever power is connected, whether the POWER switch is
set to ON or STBY,
| WARNING |
BEFORE APPLYING AC POWER, THE INSTRUMENT AND ALL
PROTECTIVE EARTH TERMINALS, EXTENSION CORDS, AUTO
TRANSFORMERS, AND DEVICES CONNECTED TO THE INSTRU-
MENT SHOULD BE CONNECTED TO A PROTECTIVE EARTH
GROUNDED SOCKET, ANY INTERRUPTION OF THE PROTEC-
TIVE EARTH GROUNDING WILL CAUSE A POTENTIAL SHOCK
HAZARD THAT COULD RESULT IN PERSONAL INJURY,
3-79. The rear panel reference outputs are still available when the
instrument is in the standby mode, and the state of the instrument is
saved as long as ac power is connected to the instrument. All parameter
and function settings are stored in the processor standby RAM.
3-80. RESET/LOCAL. This key is generally used to abort any current
activity to return to counting, and will restart a measurement if the
counter is already in the measurement mode. Pressing RESET/LOCAL
will clear any Error messages which may appear, and will also exit the Self
Check or diagnostics modes. When entering data via the front panel
keyboard, pressing RESET/LOCAL aborts any partially entered sequence,
and the counter returns to the current measurement mode. If the
counter is in diagnostics mode, RESET/LOCAL will abort the diagnostic,
and return the counter to the current measurement mode.
3-81. if the instrument is in the remote operating mode, then the
RESET/LOCAL key also acts as a “return to Local” key. Itisthe only active
key when the counter is in the remote mode, and may be disabled using
the “Local Lockout” HP-IB function, or the “Keyboard Lockout”
diagnostic {Diag 98), (Refer to diagnostic descriptions in Section VIH,
Service.)
3-82. OFFSET. This function allows the user to enter a signed, constant
frequency value which will be automatically added to each measurement.
When the OFFSET key is pressed, the current offset value is displayed until
the key is released, after which the counter continues measuring,
displaying the sum of the input frequency plus the offset. A negative
offset is displayed with a minus sign immediately to the left of the digits.
HP 53508/5351B/5352B
Operation and Programming
For a positive offset, a blank is displayed to the left of the digits. Changing
the sign may be done at any time during parameter entry, and the sign
may be toggled as many times as the user wishes. The offset is entered in
megaHertz, down to 1 Hz resolution. After the decimal point is pressed,
subsequent digits are displayed to the right of the 1 MHz position in the
parameter section. The final, entered offset is displayed with no decimal
point, as it is fixed-point notation. To turn off the offset, press the OFFSET
key again.
3-83. The offset value may be entered using the Function/Data keys or
by pressing the LST FRQ (Last Frequency) key. When using the LST FRQ
key, the offset is set to the negated value of the last frequency measured,
exclusive of any math function that may be active.
SCALE 3-84. SCALE. This function allows the user to enter asigned, dimension-
less constant to be used as a multiplication factor, Pressing the SCALE key
turns on the Scale function, and the current scale value is displayed until
the SCALE key is released. After the key is released, the counter
continues measuring, displaying the product of the measured frequency
multiplied by the scale factor. When combined with the Offset function,
the counter will automatically compute and display the following:
| (Fin) X (SCALE) | + OFFSET
To turn off the Scale function, press the SCALE key again.
SMOOTH 3-85. SMOOTH. Pressing the SMOOTH key initiates the “automatic
resolution” algorithm, causing the counter to display only the digits that
are stable. The input frequency is averaged to remove small deviations
and increase resolution, and the unstable digits are masked in the same
manner as the RESOLUTION display. Pressing the SMOOTH key a
second time disables the Smooth function. There is no data entry
associated with this function.
SET / ENTER 3-86. SET/ENTER, This key is used for parameter value entry for various
keyboard functions. Parameter value entry is always initiated by pressing
Co) the SET/ENTER key once, after which the counter will display “SET”. The
counter then waits for a function key to be pressed. After a function key
has been pressed, the keyboard is in the “parameter entry mode”, and
the data entry assignment of each key is accessible (Refer to Table 3-21,
Parameter entry is terminated by pressing the SET/ENTER key a second
time (entering the value into memory).
3-87. When setting a parameter value, the entire sequence may be
aborted at any time by pressing the RESET/LOCAL key. The counter will
then return to the state it was in before the SET/ENTER key was pressed.
de RESOLUTION mM 3-88. RESOLUTION. This function allows the user to change the
E number of significant digits displayed after measurements. A higher
Г ( resolution results in a longer gate time; the lower the resolution, the
shorter the gate time. This parameter may be varied from 1 Hz (highest
resolution) to 1 MHz (lowest resolution) using the INC (increment) and
DEC (decrement) keys, in decade steps. Since the minimum gatetimeis 1
millisecond, resolutions of less than 1 kHz change only the displayed
resolution, not the measurement time.
3-11
HP 5350B/5351B/5352B
Operation and Programming
3-89. The current setting of the resolution may be displayed while
counting by pressing the RESOLUTION key. It will remain displayed until
the key is released. The nonsignificant digits of a measurement are
rounded off and, in the display, are either blanked or replaced by the
asterisk symbol ¥ , depending on the resolution.
HP-IB ADDRESS 3-90. HP-1B ADDRESS. This key allows the user to display and set the
E HP-1B address. At power-up, after reapplication of ac power, the HP-IB
4 ( address of the counter is determined by the switch settings on the HP-IB
board (rear panel address switch). Pressing the HP-IB ADDRESS key will
display the current address until the key is released, after which the
instrument resumes counting. The current address can be changed by
going to the parameter entry mode (using the SET/ENTER key). Addresses
0 through 30 are valid bus addresses. Address 31 is used to set the counter
to the TALK ONLY mode.
3-91, If the counter is switched to STBY and then back to ON, it will
remain set to the HP-IB address entered via the front panel keyboard. If
the ac power source to the instrument is disconnected and then
reconnected, the instrument will default to the address determined by
the setting of the rear panel address switch.
4 DIAGNOSTICS sp 3-92. DIAGNOSTICS. This function key allows the user to call up
Pu diagnostic routines which perform various tests on the instrument for
troubleshooting and measurement information. Pressing the DIAGNOS-
TICS key once turns on the diagnostic function, and the counter will
carry out the current diagnostic routine. The current diagnostic will be
that which was last entered by the user, or if the counter has just been
turned on, the diagnostic will default to Diag 1. To exit the diagnostic
mode, press the DIAGNOSTICS key a second time, or press the
RESET/LOCAL key.
3-93. The user may enter a new diagnostic number (from 1 to 99) in the
parameter entry mode, using the Function/Data keys for numeric entry.
Most of the diagnostics may also be entered using the INC (increment)
and DEC (decrement) keys. Other instrument functions may be set up
while in diagnostic mode (for example, measurement modes, resolution,
etc.). Refer to the diagnostic descriptions in Section VIH, Service,
3-94. There are 37 user-callable diagnostics available for testing instru-
ment circuitry. Since not all of the numbers between 1 and 99 are used,
the counter will show a “NOT AVAILABLE” message on the display if the
user should attempt to enter an invalid diagnostic number. To get out of
a “NOT AVAILABLE” diagnostic condition, the operator may use the INC
or DEC keys to move to the nearest valid diagnostic number, or use the
SET/ENTER key sequence to enter a valid number. The Diagnostic mode
may also be exited as described previously, using the DIAGNOSTICS or
RESET/LOCAL key.
dE SAMPLE RATE mp 3-95. SAMPLE RATE. This function sets the dead time between measure-
Pu ments. The minimum time (Fast) allows the counter to count as
frequently as possible. The other extreme (Hold) will keep the last
measurement until the TRIGGER key is pressed to start a new measure-
ment. When in “Hold”, the HOLD annunciator is lit. While setting the
sample rate, the GATE annunciator flashes at the currently selected
sample rate. Pressing the SAMPLE RATE key while the instrument is
3-12
HP 5350B/5351B/53528
Operation and Programming
counting causes the current sample rate to be displayed until the key is
released, after which the counter returns to counting.
SELF CHECK 3-96. SELF CHECK. As a quick operation verification, the user may press
nu the SELF CHECK key. Self Check calls up a sequence of diagnostic
subroutines to test the measurement circuitry. The tests have been
ordered such that no test depends on more than one untested circuit
assembly.
3-97. 1f the Self Check passes, a “PASS” message is displayed for about
3 seconds, and the counter returns to the measurement cycle, If Self
Check fails, a “FAIL” message is displayed. After a failure, the Self Check
sequence restarts and the failure message will continue to be displayed.
Self Check failures may be bypassed by pressing the RESET/LOCAL key.
The remaining tests in the Self Check sequence will be carried out, until
another failure occurs, or the last test is completed. If any failure occurs,
the last “FAIL” message (after the last test is done) will include the word
“SELF” at the right end of the display. Pressing the RESET/LOCAL key
again will return the counter to its previous measurement mode.
3-98. HIGH RESOL. This function allows the user to select a resolution
greater than 1 Hz for measurements below 10 MHz. The High Resolution
function applies only to INPUT 2, TMQ impedance measurements.
Pressing the HIGH RESOL key once turns on the function, and the HIGH
RESOL annunciator will light. Since this function is active only in the
TMQ Low Frequency measurement mode, the HIGH RESOL annunciator
will NOT light when the counter is in the Auto, Manual, or 500
measurement mode. Pressing the key a second time will turn off the High
Resolution function. There is no data entry associated with this function.
3-99. The resolution obtained using the High Resolution function
depends on the input frequency, and the gate time will remain constant
at 1 second. The Smooth function takes precedence over the High
Resolution function. The High Resolution function takes precedence
over the standard counter resolution, if the counter is in the INPUT 2,
1M measurement mode.
FMRATE/TRACK 3-100. FM RATE/TRACK. The FM Rate/Track function applies only
E when using the INPUT 1, AUTO mode. This function is used to select the
acquisition method during high frequency measurements to improve
signal tracking or to compensate for very low FM rates, Pressing the FM
RATE/TRACK key cycles the function through three states; Normal Rate,
Low Rate, and Track. When set to Low Rate, the measurement gate time
of the counter is increased to ensure an accurate measurement of signals
with FM rates as low as 45 Hz, and high deviation. When set to Track, a
faster acquisition time is used to improve signal tracking of frequencies
with FM rates equal to or greater than 300 kHz, and high deviation.
3-101. One of three front panel annunciators (FM NORM, LOW,
TRACK) will light to indicate which FM Rate/Track mode is currently
selected when in Auto mode. When the instrument is not in Auto mode,
none of the annunciators will appear. There is no data entry associated
with this function.
TRIGGER 3-102. TRIGGER. When the counter sample rate is set to HOLD,
pressing the TRIGGER key starts a new measurement. There is no data
entry associated with this function.
HP 5350B/5351B/5352B

3-103. 500. This key selects the Low Frequency, 500 input mode
(INPUT 2) for measuring low frequency (10 MHz to 525 MHz) signals
from 500 sources. Pressing the 500 key turns on this mode, and disables
the INPUT 1 high frequency circuit by turning off the A12 Microwave
Assembiy. The measured frequency will be displayed in the parameter
section of the display; the message section will be blank. To exit the 500)
mode, press one of the three other measurement mode keys (AUTO,
MANUAL, TM}; pressing the 500) key a second time has no effect.
There is no data entry associated with this key.
3-104. IMA. This key selects the Low Frequency, TMQ input mode for
measuring frequencies from 10 Hz to 80 MHz. Pressing the 1M) key
turns on this mode, and disables the INPUT 1 high frequency circuit by
turning off the A12 Microwave Assembly. The measured frequency will
be displayed in the parameter section of the display; the message section
will be blank. To exit the TM mode, press one of the other measurement
mode keys; pressing the 1M() key again has no effect. There is no data
entry associated with this key.
3-705. AUTO. The instrument powers-up in the automatic measure-
ment mode, and the AUTO annunciator on the front panel will be lit. in
this mode, the counter will automatically acquire and measure the signal
at INPUT 1. Measurements are displayed in the parameter section of the
display; the message section of the display remains blank, or displays
“OVRLOAD” if an overload condition exists. To exit the Auto mode,
press one of the other measurement mode keys; pressing the AUTO key
a second time has no effect. There is no data entry associated with this
key.
3-106. MANUAL. A Center Frequency (CF) must be specified for the
counter to measure when in this mode. To enter this mode, press
MANUAL. The most recent measurement will then become the Manual
Center Frequency. The CF will be displayed until the key is released, then
the counter will begin counting in Manual mode. The measured
frequency will be shown in the parameter section of the display; the
message section will remain blank, or display “OVRLOAD” if an
overioad condition exists. To exit the MANUAL mode, press one of the
other measurement mode keys; pressing the MANUAL key a second
time has no effect. |
3-107. To enter a center frequency, press the SET/ENTER key, then
press MANUAL, The current center frequency is displayed, and may be
changed. The CF may also be entered using the LST FRQ key. In this case,
the CF is set to the value of the last measured frequency, exclusive of any
math functions that may be active. Pressing the SET/ENTER key a second
time enters the new CF into memory, and the counter will begin
counting using the new value.
3-108. If a manual CF is entered which is greater than 33 GHz [43 GHz,
5352B] or less than 500 MHz, then an error is displayed. After the user
clears the error, the counter returns to counting using the previous value.
if a CF containing fractional-megaHertz values is entered, the fractional
portion is truncated on pressing the SET/ENTER key. The CF entered
should be no more than 20 MHz from the input frequency for inputs in
the 1 GHz-MAX GHz range, and no more than 3 MHz from the input
HP 53508/5351B/5352B
Operation and Programming
frequency for inputs in the 500 MHz-1 GHz range. If the CF is too far from
the input frequency, the counter may display an incorrect measurement.
3-109, Front Panel Display and Annunciators
3-110. All HP 5350B/51B/52B display functions are performed by a Liquid Crystal Display
Assembly. Annunciation for all operating modes is indicated by arrows at the bottom of the
display which, when lit, point to the function names marked on the front panel just beneath the
LCD panel.
3-111. The front panel display consists of 24 LCD characters, as shown as shown in Figure 3-1.
During measurement and parameter entry, the characters are divided into a parameter section,
and a message section. The parameter display section has room for 12 digits, grouped in sets of
three by blank characters between each group. The message section has 8 characters available,
the first usualiy being blank to serve as a separator between the message section and the
parameter section. The content of the display will be different for each operating mode. The
various HP 5350B/51B/52B functions and their corresponding displays are described in the
Operating Procedures beginning at paragraph 3-162.

3-115: The various modes and functions of the HP 5350B/51B/52B are labeled on the front panel
just beneath the LCD, as shown in Figure 3-2. When an operating mode or function is selected, an
arrow-shaped annunciator ( ~ ) appears at the lower edge of the display, pointing to the name of
the selected mode or function. Table 3-4 contains a brief description of each of the front panel
annunciators.
Table 3-4. Front Panel Annunciator Descriptions
1) GATE
The GATE annunciator shows the status of the counter's gate. The GATE annunciator
flashes during measurements to indicate the opening and closing of the gate.
2 HOLD
The HOLD annunciator lights when the sample rate of the counter has been set to the
slowest possible rate. When.in HOLD, the counter keeps the last measurement until a
new measurement is triggered using the front panel TRIGGER key or the HP-IB
TRIGGER or TRG command. The annunciator remains on until the sample rate is
changed to a rate other than HOLD,
3) OFFSET
The OFFSET annunciator lights when the Offset Frequency function has been enabled.
The displayed frequency will be that of the measured frequency plus the value of the
entered offset frequency.
4) SCALE
The SCALE annunciator lights when the Scale function has been enabled. The
displayed frequency will be that of the measured frequency multiplied by the scale
factor.
5) SMOOTH
The SMOOTH annunciator lights when the Smooth function has been enabled. The
frequency displayed will have unstable digits masked.
6) REM
The REM annunciator lights when the counter is under remote control. Refer to
Remote Programming via the HP-IB, paragraph 3-225, for further information.

HP 5350B/53518/53528B
Operation and Programming
3-116. REAR PANEL FEATURES
3-117. The following paragraphs describe the rear panel features of the HP 53508/518/52B. All
rear panel features of the instrument are shown in Figure 3-3.
3-118. AC Power input Module
3-119. The AC Power Input Module (A13) accepts the three-wire ac power cable (W1),
permitting operation from 100-, 115/120-, 220-, and 230/240- volt ac sources. The power module
contains a printed circuit line voltage selector card, which must be positioned to agree with the
voltage of the power source, When the cardis pluggedinto the module, the number visible in the
module window indicates the nominal line voltage to which the instrument must be connected.
The correct value line fuse must be installed after the card is inserted (Refer to Section II,
paragraph 2-8, Line Voltage Selection, and Figure 2-1 for further information). The protective
grounding conductor connects to the instrument through this module.
3-120. TCXO Adjustment
3-121. This opening in the rear panel allows adjustment of the Temperature Compensated
Crystal Oscillator standard timebase (but not the optional oven oscillators} without requiring
removal of the instrument covers. Refer to Section V, Adjustments, for timebase calibration
instructions.
3-122, HP-IB Connector
3-123. This input/output interface connector provides remote control capabilities with the
Hewlett-Packard Interface Bus (HP-18). For a complete description of the HP-IB capabilities, refer
to paragraph 3-225, Remote Programming via the HP-1B.
3-124. HP-IB Address Switch
3-125. The HP-IB Interface Address Switch (ADDR) is a bank of seven switches used to manually
set the remote control address of the counter. The five rightmost switch positions are externally
accessible to the operator for setting the address. The two leftmost switch positions are not used
for normal operation. For a complete description of address selection, refer to Table 3-8 Address
Selection in the Remote Programming instructions in this section.
À 3-126. External Reference In
3-127. An external reference input is provided for a 1 MHz, 2 MHz, 5 MHz, or 10 MHz reference
source, If an external reference source is applied to this input, the counter automatically switches
to using the external reference as its timebase, and turns off the TCXO standard timebase. If an
oven oscillator is installed, power to the oven is maintained, but the internal oscillator signal is
disconnected. A detection circuit in the timebase buffer sends a control signal to the
microprocessor and the EXT REF display annunciator lights to indicate that an external source is
being used. External reference requirements are listed in Table 7-1, Specifications.
3-128. 1 MHz Out, 10 MHz Out
3-129. Two rear panel signal outputs, 1 MHz and 10 MHz, are available for reference and
calibration. The signals remain present when the instrument is in Standby and as long as ac power
is connected to the instrument. Refer to Table 1-1, Specifications for the output signal
specifications.
3-27.

3-130. IF Out
3-131. This output provides the IF signal resulting from the mixing of theinput and LO harmonic
frequencies for monitoring with a spectrum analyzer or oscilloscope. This signal is available only
when a high frequency (INPUT 1) measurement is being made. Refer to Table 7-7 for IF output
specifications.
3-132. Rear Panel Input Connectors {Option 002)
3-133. If Option 002 is installed in the 5350B or 5351B, the frequency inputs for the counter
(INPUT 1, INPUT 2) are located on the rear panel, and covers are placed over the front panel
openings. The rear panel inputs are used for all the same functional modes of operation as the
front panel inputs. The performance specifications for the HP 53508 or 5351B equipped with
Option 002 are listed in Table 1-1, Specifications.
3-134. OPERATOR’S MAINTENANCE
3-135. The only maintenance the operator should normally perform is replacement (when
necessary) of two fuses: the primary power fuse (F1) located within the AC Power Input Module
on the rear panel, and the Low Frequency Input fuse (12F1) located in the front panel INPUT 2
connector, For instructions on how to change the primary power fuse, refer to Section Il,
paragraph 2-8, Line Voltage Selection, and Figure 2-7.

To prevent damage to the instrument, make sure that the voltage
selector card is set to the voltage of the power source, and that
the correct fuse is installed, before connecting the instrument to
ac power lines. Refer to paragraph 2-8.
3-139. The HP 5350B/51B/52B has a two position (STBY/ON) power switch. For the Option 001
Oven Oscillator Timebase or the Option 010 High Stability Timebase, it is important that the
instrument remain connected to the power source in the Standby (STBY) mode when notin use,
This supplies power to the crystal oscillator oven, maintaining a constant oven temperature, thus
eliminating the need for a warm-up period. When the Standby mode is not used, and power is
disconnected from the instrument, allow 30 minutes from the application of external power in the
ON mode for the instrument (crystal oven) to warm-up.
| WARNING |
BEFORE APPLYING AC POWER, THE INSTRUMENT AND ALL
PROTECTIVE EARTH TERMINALS, EXTENSION CORDS, AUTO-
TRANSFORMERS, AND DEVICES CONNECTED TO THE INSTRU-
MENT SHOULD BE CONNECTED TO A PROTECTIVE EARTH
GROUNDED SOCKET, ANY INTERRUPTION OF THE PROTEC-
TIVE EARTH GROUNDING WILL CAUSE A POTENTIAL SHOCK
HAZARD THAT COULD RESULT IN PERSONAL INJURY.
3-140. OPERATOR'S CHECKS
3-141. The following procedures will verify the basic operation of the HP 5350B/51B/52B. These
tests are not intended to verify the overall accuracy or performance specifications of the
instrument. They should, however, provide the operator with a quick method of determining that
the counter is operating properly. Two operator tests are described below: a Power-Up Seif Test,
and a Keyboard Check. The operator should perform both tests.

3-142. Power-Up Self Test
3-143. To perform the Power-Up Self Test after the instrument has been turned on, cycle the
POWER switch to STBY (Standby), then back to ON. During the Power-Up Self Test, all front panel
LCD display segments and annunciators will light momentarily, followed by the momentary
display of the current HP-IB address. When all tests have been successfully completed, the
counter measurement status will be restored to the conditions that were set before the POWER
switch was cycled. (Note that the Power-Up Self Test is a more extensive test of the instrument
than that carried out when the front panel SELF CHECK key is pressed. Refer to the diagnostic
descriptions in Section VIII, Service, for details.)
3-144. If ac power was applied to the instrument just prior to turning it on, the counter will
initialize itself to the following conditions when the POWER switch is set to ON:
a. Measurement modes —
Auto: ON
Manual: OFF
Manual CF: 1 GHz
Low Frequency 500: OFF
Low Frequency TM: OFF
bh. Measurement modifiers —
Sample Rate: FAST

3-150. Pressing the RESET/LOCAL key will cause the instrument to display “RESET” momen-
tarily, and then exit from the test.
3-151. Power-Up Failures
3-152. A number of failure messages are possible during the Power-Up Self Test sequence.
Almost all of the messages will be in a form similar to the one shown below:
IT ww KI HT
Fria a ADJ
— In this example, Diagnostic 20 (Low Frequency Input, 500 Verification: 35 MHz) has failed,
indicating a possible problem in the A2 Low Frequency Input Assembly.
3-153. if any test during the Power-Up sequence fails, the “FAIL” message will remain until the
user presses the RESET/LOCAL key. At that point, the next test is executed (if possible). By
pressing the RESET/LOCAL key, most failures can be bypassed to allow the counter to proceed
with the Power-Up test sequence, When the last test is complete, the counter will proceed to the
normal operation mode, if possible.
3-154. Refer to Section Vii, Service, for troubleshooting information if a “FAIL” message appears

d. HP-IB, paragraph 3-200.
e. Diagnostic Functions (including Auxiliary Functions), paragraph 3-204.
3-167. Each operating procedure shows the key (or key sequence, as necessary) to be pressed to
perform the desired function, and the resultant display. A brief description of the effect of each
function is given, and the allowable range for any parameter values are described, if applicable.
The Power-up default conditions for each function are also given, with the term “Power-up’
referring to connecting ac power to the instrument and then turning it on, as distinct from
“Standby”, which assumes that ac power is continuously connected.
3.168. If the POWER switch is turned from ON to STBY, and then back to ON, the counter will
retain the setup conditions which were active before the POWER switch was toggled. The only
exceptions to this are the HP-IB interface, which is cleared, and the diagnostic mode, which will
default to its power-up conditions: DIAG 1, OFF. Refer to Table 3-2 for a list of all Power-up
default and Standby conditions.
3-169. Most of the procedures include an example of a typical display for the operation being
described. Some multi-key procedures show examples of displays that will occur at certain points
in the indicated key sequence. The actual contents of each function display will depend on the
function in progress, and on the frequency being measured.

3-172. Using certain functions, such as Offset or Scale, may involve the entry of numeric data
using the Function/Data keys. Other functions allow selection of their parameter values froma
specific range using the INC (increment) and DEC (decrement) keys, such as Sample Rate and
Resolution. Still other functions simply toggle, such as the Smooth function. If the user should
attempt to enter the incorrect type of data as afunction parameter value, the counter will display

OPERATING PROCEDURES
3-212. Special Diagnostic Exit Procedures
3-213. Most diagnostic functions can be exited by pressing the DIAGNOSTICS key or the
RESET/LOCAL key. Some diagnostics require special exit procedures, as follows:
а.
To exit from a Diag 1 failure, press the DIAGNOSTICS key; pressing the RESET/LOCAL key
will only scroll through the tests.
To exit Diag 51 (LO Synthesizer Verification - User-Entered Frequency) or Diag 70
(Keyboard Test), press the RESET/LOCAL key; the DIAGNOSTICS, INCREMENT, and
DECREMENT keys cannot be used to exit.
The only way to exit from Diag 97 (IF 175 MHz Filter Adjust) is to switch the counter to STBY.
When the counter is powered-up again, the Diagnostic number defaults to 1.
The only way to exit Diag 98 {Keyboard Lockout}, and Diag 99 (Display Lockout) is by
entering a special key sequence (7, 4, 0, RESET/LOCAL), or by removing ac power to the
instrument. After exiting Diag 98 or 99, the diagnostic number defaults to 1.
When pressing the special key sequence to exit Diag 98 or 99, the operator should allow a
short amount of time (about 1 to 2 seconds} to elapse between each key press. Pressing the
keys too quickly prevents the counter from responding properly to each key in the
sequence, causing the counter to remain in the diagnostic mode.

Operation and Programming
3-214. AUXILIARY FUNCTIONS
3-215. Eight of the front panel diagnostics, Diag 2 through 9, are referred to as auxiliary
functions. When an auxiliary function is activated, the counter continues to carry out a normal
measurement cycle, but does not display the measured input frequency. Instead, each auxiliary
function causes the counter to display a particular measurement parameter used to compute the
measured input frequency. The following paragraphs contain brief descriptions of the auxiliary
functions. Unless otherwise noted, a given auxiliary function will display a measurement
parameter for either an INPUT 1 or INPUT 2 measurement.
3-216. The auxiliary functions are selected using the Diagnostic Function operating procedures
beginning at paragraph 3-209. When the counter is in the auxiliary function mode, it does not
display a pass or fail message, but displays only the measurement parameter. The contents of each
auxiliary function display depend on the particular parameter involved. During any auxiliary
function display, an overload condition, if present, will be indicated by the letters “OVLD”
replacing a portion of the display. Refer to Section VIII, Service, for detailed descriptions of all
diagnostics, including auxiliary functions, and for information on the various measurement
parameters displayed.
3-217. Display If

Effect: The counter will display the value of the IF, showing one digit greater than the
chosen resolution (two digits for 1 Hz). The chosen resolution and sample rate will affect the
display, and also the Smooth function, if enabled. The IF will be displayed only when the
counter is set to INPUT 1; when set to INPUT 2, the counter will display the low frequency
measurement.
3-218. Display MRC E & T Register Contents

Effect: The counter will display the contents of the MRC Events (E) and Time (T) registers,
including overflow. The chosen resolution will affect the contents of the Time register (gate
time), but the selected sample rate will not affect register contents. Math functions, if
enabled, also have no effect. The T register portion of the display includes the fraction {in
decimal form) calculated from the interpolator data.

sweep. In Manual mode, the display of the LO value will be stable. If the counter is switched
to INPUT 2, the last LO value from either of the INPUT 1 modes {Auto or Manual) will
appear.

3-225. REMOTE PROGRAMMING VIA THE HP-IB.
3-226. Introduction
3-227. The HP 53508/51B/52B Microwave Frequency Counter is compatible with the Hewlett-
Packard interface Bus (HP-1B). The HP-1B interface is installed as standard equipment and allows
the instrument to respond to remote control instructions and output measurement data via the
HP-IB. At the simplest level, the HP 5350B/51B/52B can output data in the “talk only” mode to
another device, such as a printer. In more sophisticated systems, a computing controller can
remotely program the counter to perform a specific type of measurement, trigger the
measurement, and collect the results.
NOTE
HP-1B is Hewlett-Packard's implementation of IEEE Std, 488-1978,
“Standard Digital Interface for Programming instrumentation”.
3.228. To remotely program the counter, the operator must be familiar with the selected
controller, the configured interface, and the local operation and functional capabilities of the HP
5350B/51B/52B. Typical controllers for the HP-IB are the 9825A/B, 9826A, 9835A, 9836A, 9816A,
9845A, or HP-85. The following manuals should provide useful background information:

3-229. HP-IB Description
3-230. The Hewlett-Packard Interface Bus (HP-IB) is a high speed parallel interface bus. All
devices on the bus are capable of being addressed at one time. However, only one device may
respond at a time, The controller is used to command a specific device to respond, and maintain
the flow of data and interface functions.
3-231. The HP-IB system uses a party-line structure {devices share signal lines). A maximum of 15
devices may be connected in an HP-IB system, in virtually any configuration desired. There must
be an uninterrupted path to every device operating on the bus. Sixteen signal lines and eight
control lines are used to interconnect devices in parallel arrangement and maintain an orderly
flow of device and interface related information.

"3.232. Interface System Terms
3-52
3-233. The following paragraphs define terms and concepts used to describe HP-1B system
operations.
a. Address: Each device on the interface is assigned an address. The address is used to specify
which device will receive information or send information.
b. Byte: A byte is a unit of information consisting of eight binary digits called bits.
c. Device: Any instrument or unit that is HP-IB compatible is called a device.
d. Device Independent Command: A command predefined by the interface standard to have
a specified bit pattern and resulting action.
e. Device Dependent Command: A command that is specific to a particular instrument or
family of instruments, which is not predefined by the interface standard. Device dependent
commands are usually sent as ASCH strings of characters,
f. Polling: Polling is a process typically used by a controller to locate a device that requires
service from the controller, There are two types of polling, Serial Poll and Parallel Poll:
1. Serial Poll: When the controller executes a serial poll, the addressed device sends one
byte of operational information called a status byte. If more than one device on the
interface is capable of requesting service, each device on the interface must be polled
until the device that requested service is located.
2. Parallel Poll: The HP 5350B/51B/52B does not have parallel poll capability.
3-234. Major Interface Functions
3-235. Each device on the interface may have one or more of the following major device
capabilities: Controller, Talker, or Listener. The controller has the responsibility of controlling
interface activity, and must be equipped with the proper interface module. Controllers transmit
all device independent commands to other devices in the interface and usually have Talker and
Listener capabilities. Only one device on the interface may be the active controller at any one
time. The HP 53508/518/52B Counter has no controller capabilities,
3-236. Talkers are devices that have the ability to send data or device dependent commands
through the interface. Note that a talker will not actually send data or information until the
appropriate command is sent by the controller. The HP 5350B/51B/528 Counter has Talker
capabilities, When the counter is talking on the interface, or is addressed to talk, the TLK
annunciator will turn on, in special situations, a device may be classified as a Talk Only device, and
send information to Listen Only devices. Such a system has no controller. For example, the
counter can be configured to TALK ONLY andsend measurement results to a printer by setting the
HP 5350B/51B/528 HP-IB address to 31.
HP 5350B/5351B/5352B
Operation and Programming
FD,
3-237, Listeners are devices with capability to receive information over the interface. When the
counter is listening, or addressed to listen, the LSN annunciator turns on. Listeners must also be
enabled by the controller to receive data or information.
3-238. Interface Capabilities
3-239. The capabilities of a device connected to the bus are specified by its interface functions.
These functions provide the means for a device to receive, process, and send messages over the
bus. Table 3-7 lists the HP-IB interface functions defined by the IEEE 488-1978 standard, including
the name, mnemonic, and a brief description. A subset identifier (the interface function
mnemonic followed by a number) indicates the specific HP-IB interface function capabilities of a
particular instrument. The specificinterface capabilities of the HP 5350B/51B/52B are also listed in
Table 3-7, including the complete subset identifiers. |

3-240. Nearly all controls on the counter can be programmed remotely, and data from the
measurements can be sent to the controller through the HP-1B. The HP 53508/51B/52B operates
as both a talker and a listener, as described in Table 3-7. The counter's output format is the same
regardless of the mode (Talk Only/Addressable). The following paragraphs describe the basic
programming capability of the HP 5350B/51B/52B Microwave Counter,
TALK: The 5350B/51B/52B can be addressed to TALK by a controller or by
entering the TALK ONLY address, 31. When addressed as a Talker, the
counter will send data to other devices on the bus, This data may be the
result of a measurement, error messages, diagnostic resuits, etc,
LISTEN: | When addressed as a Listener, the instrument will accept any number of
commands from a controller on the bus. These commands are used to
program the instrument operation.
SERVICE REQUEST: SRQ will be generated on the interface when an enabled status bit is set.
The 5350B/518/52B has the capability to request service asynchronously
from the controller in charge of the bus. Refer to paragraphs 3-261and 3-
268 for a description of the Service Request Mask (SRQMASK) command.
REMOTE/LOCAL: At power-up, the counter is under front panel (local) control. To program
| | the 5350B/518/528, it must be placed in Remote, Once in Remote,
programmable functions cannot be affected by the front panel controls.
The RESET/LOCAL key may be used to manually return to local control
only ¡f the Local Lockout (LLO) is off. if Local Lockout is on, the
RESET/LOCAL key isignored, and the bus command LOCAL must be sent
to disable LLO.
PARALLEL POLL; The 5350B/51B/528 does not respond to parallel poll.
DEVICE CLEAR: When a universal or selected device clear isreceived, the 5350B/51B/52B
clears any errors present, clears all input and output buffers, and resets
the hardware for a new measurement.
DEVICE TRIGGER: When a device trigger is received, the counter will start a new
measurement, if the sample rate is set to HOLD, If the sample rate is not
set to HOLD, the device trigger command is ignored.
CONTROLLER: The 5350B/51B/52B cannot be used as controller,
3-241. Front Panel Interface Status Annunciators
3-242. The remote status of the HP 5350B/51B/52B is indicated on the front panel by four
interface Status annunciators in the liquid crystal display. To indicate the Interface Status
function, an arrow {+ ) appears atthe bottom of the display just above the name of one of the four
status labels on the front panel: REM, LSN, TLK, or SRQ. The REM annunciator lights to indicate
the counter is under remote control. The LSN annunciator lights to indicate the counter is
addressed to listen (receive commands). The TLK annunciator lights to indicate the counter is
addressed to talk (send data). The SRQ annunciator lights to indicate that a service request
condition exists (as determined by a set service request mask bit).

3-243. Address Selection
3-244. To use the HP 5350B/51B/52B in an HP-1B system, the counter must be set to the desired
address, as described in Table 3-8. The ADDRESSABLE mode is used whenever a calculator or
other controller is used with the system, and the HP 5350B/51B/528 functions as a talker and a
listener. The TALK ONLY mode is used when the counter is operating under its own control (no
controller on bus) and outputting results to another device on the bus, such as a printer. In the
TALK ONLY mode, the HP 5350B/51B/52B functions only in an output condition, and the
receiving device must be set to LISTEN ONLY,
3-245. The HP-18 address for the HP 5350B/51B/52B can be set in one of two ways: by front panel
entry or by setting the rear panel HP-IB address switch. The address set using the rear panel switch
is a default address which the counter will be set to if ac power has been removed and then
restored to the instrument. If the counter has been switched to STBY (using the POWER switch),
the address set by front panel keyboard entry will be retained as the HP-IB address. Refer to Table
3-8 for all possible address settings and the corresponding ASCII codes for Talk and Listen, in the
ADDRESSABLE mode and in the TALK ONLY mode.
3-246. To set or change the HP 5350B/51B/52B HP-IB Address via the front panel, refer to the
front panel operating procedure for entering the HP-IB address, at paragraph 3-203.
3-246A. To avoid unintentional HP-IB address change, do not interrupt power-up sequence, i.e.
toggling STBY/ON power switch of 5350B/5351B/5352B.

Note: Be sure that the instrument address is not set to the same address as the controller. Typical HP controilers use
address “21” as a preset address, thus the use of address “21” as the HP 5350B/51B/52B address code should be
avoided, |
3-247. The examples used in this section assume an address setting of 14. When using a
controller such as an HP 9826A, 9836A, 9845A, or HP-85 calculator, the controller addresses the HP
5350B/51B/52B by using select code 7, plus the instrument address. Therefore, all examples in this
manual will use the code 714 to address the HP 5350B/51B/52B to talk or listen. The ASCII
characters for this same address setting are “N”’ for a talk address, and ‘“’’ for a listen address, The
ASCH characters are used when the controller is an HP 9830A calculator.

3-248. Interface Commands
3-249. The commands the counter recognizes can be separated into two classes: device
independent commands and device dependent commands. Device independent commands are
defined by the interface standard document and are the same in all instruments. These commands
are identified by a three letter mnemonic such as GTL, which represents Go to Local. Device
independent commands are sent as encoded bytes on the interface and not as ASCII strings. Thus
these commands cannot be sent using the OUTPUT statement on the HP-85. However, many
controllers do incorporate a command of the form SEND7;CMDnnn, where nnn is the decimal
equivalent to the bit pattern corresponding to a particular device independent command. A
detailed description of Device Independent Commands begins at paragraph 3-251.
3-250. Device dependent commands are unique to the instrument and are defined by the
instrument designer. They are normally sent to an instrument as ASCII strings. A detailed
description of Device Dependent Commands begins at paragraph 3-273.
3-251. Device independent Commands
3-252. A list of supported independent command mnemonics, and the full name of each
command, is given in Table 3-9,

HP 5350B/5351B/5352B
GET If the instrument is addressed to listen, GET aborts the current measurement, and triggers
the next measurement immediately. It is equivalent to pressing the TRIGGER key.
CTL If the instrument is addressed to listen, GTL returns the instrument to (local) front panel
| operation. Local Lockout is not cleared. |
IFC The instrumentuntalksandunlistens, and the interface initializes to anidlestate (no activity
on the bus).
LADn If n matches the instrument address, the instrument becomes a listener.
LLO The front panel RESET/LOCAL key is disabled, if the instrument is in remote.
MLA MLA is the listen address (LADn) that matches the instrument address,
MTA MTA is the talker address (TADn) that matches the instrument address.
NRE The instrument returns to (local) front panel operation; Local Lockout is cleared.
NUL No effect when received by the instrument.
REN The instrument enters the remote state, and is enabled to respond to interface commands
when addressed as a listener,
SDC If the instrument is a listener, will cause the same response as DCL.
SPD Terminates serial polling, and returns the instrument to a normal talker state, to output
device dependent data rather than status information.
SPE Establishes serial polling, and enables the instrument to send the serial poll status byte,
when addressed to talk.
TADn If n matches the instrument address, the instrument becomes a talker,
UNL The instrument is unaddressed and terminates listening. A single device cannot be
unaddressed without unaddressing all listeners,
UNT Unaddresses the instrument, if currently a talker, and terminates talking. Addressing
another talker on the interface automatically unaddresses any current talker.
3-254. Meta Messages
3-255. To simplify the use of the HP-1B interface, Hewlett-Packard has developed what is called
the Meta Message concept. Rather thanrequiring the user to remember allthe deviceindependent
messages and their interactions, useful sequences of these commands have been integrated into a
single command on many of HP’s controllers. For example, to clear the instrument at address 14
using the device independent commands, it is necessary to send the sequence ATN, UNL, MTA,
LAD 14, SDC. The HP-85 command, CLEAR714, sends the same sequence with no further user
interaction. This greatly simplifies the use of the interface.
3-256. Many of the meta messages implemented on the HP-85 may be sent in either of two forms,
with addressing or without addressing. The form with addressing will normally address a particular
device to listen. For example, the command REMOTE7 will send REN without making any device a
listener; while the command REMOTE714 will send REN, and then make the device at address 14 a
listener. In the following tables, the form with addressing is shown.

information. A description of these messages, and the response of the HP 5350B/518/52B to each
message is provided in Table 3-70. Also included is the typical interface message sequence that
corresponds to each meta message. The interface message sequences are typical in that different
controllers may send different sequences for a given meta message, but will produce the same
results,

3-259, Remote Versus Local Measurements
3-260. The measurement cycle performed by the HP 5350B/51B/52B when in Remote differs
from that performed when the instrument is making a Local measurement. When in Local,
harmonic number determination takes place once every measurement cycle. In Remote,
harmonic number determination takes place every 10 measurements. The “HARMDET”
command may be used to set the harmonic number determination to take place after a desired
number of measurements (when in Remote), as described in paragraph 3-327. If the counter is
returned to Local after a “HARMDET” command has been passed, the number of measurements
set by the “HARMDET” command are lost, and the counter returns to determining the harmonic
number every measurement (in Local}, or every 10 measurements (if returned to Remote
operation).
3-261. SRQ and Status Byte
3-262. The counter can send a service request (SRQ] to the controller to indicate the need for
attention, and can interrupt the current sequence of events. Typically, SRQ indicates data is ready
to transmit and/or an abnormal condition exists. The counter sends an SRQ to the controller after
a 0 to 1 transition of an enabled condition, as defined by the Service Request Mask. The Service
Request Mask (SRQMASK command) must be set prior to the conditions, as described in
paragraph 3-268. The HP 5350B/51B/52B can send an SRQ to the controller under any, or all, of the
following conditions:
Power On: The POWER switch has been set to ON, and the power-up test is completed,
Local: The counter is under local control,
Overload: An overload condition exists on INPUT 1,
Error: An Error condition exists.
Measurement Complete: À measurement has been completedandis available for collection.
Most useful when the sample rate is set to HOLD (for triggered measurements).
Data Ready: Query resultready. The counter has responded to arequestfor data, andis ready
to output the data.
3-62
HP 5350B/5351B/53528
Operation and Programming
3-263. In general, the controller can read the counter Status Byte, shownin Table 3-12, atany time
to check selected operating conditions. During remote operation, the Service Request Mask
command (SRQMASK,n) may be usedto identify the conditions which you fee! may require service
or data collection, by masking selected bits of the Status Byte.

128 64 32 16 8 4 2 1
3-264. Once SRQ has been sent, the controller identifies which condition or conditions caused
the Service Request by conducting a Serial Poll of all devices on the bus, reading the Status Byte
from each device. For example, with the HP-85, “A=SPOLL (714) requests the 8-bit binary Status
Byte, and sets the variable “A” equal to the value of the Status Byte. When the HP 53508/51B/528
Status Byte is read, conditions that exist will be set to 1, whether or not they were enabled as a
condition to generate SRQ.
3-265. The number returned will be a decimal equivalent to the sum of the different status bits
that have been set. For example, the instrument sends a service request (SRQ), and reading the
Status Byte returned a value of “70”, This number (64+4+2=70) signifies: the RQS FLAG (Request
for Service) is set, there is an error, and the measurement is complete. All bits of the Status Byte
(except D6 and D7) are set (bit = 1) or cleared (bit = 0) regardless of the Service Request Mask. Bit
D7 is not used (i.e. itis always zero), and bit D6 (RQS FLAG) is only setif one of the other bits in the
Status Byte is enabled as a condition to generate an SRQ by the setting of the Service Request
Mask. The special function of the RQS FLAG bit is explained in the Service Request Mask
description, beginning at paragraph 3-268.
3-266. The Status Byte can be displayed by executing the “DISP A” statement after the
: “A=SPOLL (714)” command (if using the HP-85). The display will be the decimal equivalent to the
sum of the different status bits that have been set. With the HP 9825A, the command “rds 714--A”
requests the Status Byte, and “dsp A” sends the status to the HP 9825A display.
3-267. Status Byte Bit Descriptions
POWER ON: The Power On bit (D5) is set after the power-up self test and HP-IB
initialization is completed.
LOCAL: The Local bit (D4) is set when the instrument is in local, and cleared when the
instrument is in remote. This bit may be used to detect that the user has
returned the counter to local by pressing the front panel RESET/LOCAL key.
OVERLOAD: The Overload bit (D3) is set when the INPUT 1 detector signals an overload
condition exists. When the input power drops below the overload threshold,
the overload bit is cleared,
ERROR: The Error bit {D2) is set whenever an error has been detected. itis cleared only
after the error has been cleared by a “RESET”, “INIT”, “CLR” or Selected
Device Clear command (via HP-1B), or by pressing the front panel RESET/
LOCAL key.

MEASUREMENT
COMPLETE: The Measurement Complete bit (D1) is set at the end of a measurement, and
cleared when a new measurement is begun. When the sample rate is set to
“FAST”, this bit will be set only briefly. To guarantee that the controller will
“catch” this bit, the counter sample rate should be set to “HOLD”. In this case,
the Measurement Complete bit is set at the end of the measurement, and is
cleared after a trigger initiates a new measurement. The Measurement Com-
plete bit is also cleared by a serial poll.
DATA READY: - The Data Ready bit (DO) is set whenever the interface output buffer contains
data to be sent over the bus. Note that the Data Ready bitis set for any output,
while the previously described Measurement Complete bit (D1) applies to
measurements only,
3-268. Service Request Mask
3-269. To select the conditions which may require service or data collection, the SRQMASK
command can be used to determine which of the bits in the Status Byte will generate an SRQ. Any
bit in the Status Byte, with the exception of the RQS bit (D6) and the POWER ON bit (D5), can be
masked so it will not generate an SRQ, even though the condition exists. To specify the service
request mask, send the SRQMASK command followed by a decimal number (SRQMASK,n),
representative of the binary sum of the bits that you want enabled (unmasked). The value о ‘п’
may be any number from 0 to 255. All SRQ conditions can be masked (disabled) by sending
“SRQMASK,0”. Hf all SRQ conditions are masked, none of the conditions will generate an SRQ.
3-270. Upon receipt of the “SRQMASK,n” command, the instrument will load the binary value
of “n” into the service request mask register. Each bit in the ‘n”’ value corresponds to abitin the
Status Byte, as shown in Table 3-13.

3-271. For example, sending the command “SRQMASK,137 will generate a service request
(SRQ) and set Bit 6 (RQS), after an overload or error condition is generated, or when data is ready
(8+4+1). The RQS bit (D6) in the Service Request Mask is labeled “don’t care” because the SRQ
line/RQS bit will be settrue ONLY if one of the other bits in the Status Byte becomes true, and the
corresponding bit in the Service Request Mask is set. Therefore, the command “SRQMASK, 77” is
equivalent to the command “SRQMASK,13.”
3-272. SRQ is asserted when one of the enabled (unmasked) conditions changes from 0 to 1.
SRQ is negated (released) after a serial poll. However, the RQS bit in the Status Byte (and the front
panel SRQ annunciator) remains set as long as the enabled condition(s} is true (1).

и 3-273. Device Dependent Commands
© 3-274. A device dependent command is a sequence of ASCH-coded bytes sent to the HP
5350B/51B/52B over the HP-1B that causes the counter to perform a specific function. There are
two types of device dependent commands: “program messages”, which change the state of the
instrument and/or the instrument function settings, and “queries”, which do not change
function settings, but cause the instrument to return data to the controller (instrument
identification, measurement setup data, etc.). The following paragraphs describe how to use the
device dependent commands to program the HP 53508/51B/52B.
3-275. HP-1B COMMAND CODES
3-276. Almost all counter local functions are programmable with individual command codes via
the HP-IB. In general, functions operate the same in remote as in local (For an exception, refer to
paragraph 3-259, Remote Versus Local Measurements). The counter may also be programmed to
perform a number of functions for which there are no front panel keyboard equivalents. The
following paragraphs contain a description of the HP-1B command syntax for programming the
HP 5350B/51B/52B, and a listing of all programming commands for the counter.
3-277. All local functions, except for POWER, SET/ENTER, and HP-iB ADDRESS, are program-
mable via the HP-1B. Most of the programmable functions have the corresponding HP-1B com-
‘mand mnemonic underlined on the front panel key label {for example, RESOLUTION). Those
functions which are not underlined are shown below:
Function Key | HP-IB Mnemonic
5000 LOWZ
TMQ HIGHZ
3-278. HP-18 Command Syntax Diagrams
3-279. Inthe following paragraphs, HP-IB command syntax is represented pictoriaily, to explain
the format in which HP-IB programming commands should be sent to the instrument. All
characters enclosed by a rounded envelope must be entered exactly as shown. Words enclosed
by a rectangular box are names of items used in the commands, and are described in the text.
Items contained within circles indicate required literals which must occur in the command syntax
exactly as shown,
NOTE
Spaces are not shown in all places where they may occur. Spaces
between command mnemonics and data are allowed in the
command string to gain greater clarity, but spaces within
command mnemonics, and within data are NOT ALLOWED.
3-280. Command elements, connected by lines, can be followed in only one direction, as
indicated by the arrowhead at the end of the line. Any combination of command elements that
can be generated by following the lines in the proper direction is syntactically correct.
3-281. Command Syntax Overview
3-282. There are four possible types of command elements: command mnemonics (referred to
as “headers”, data, program message separators, and data separators. A command can consist of
a header alone or a header followed by one or more fields of data. A separator is required
between headers and data, between data fields, and between each command, as shown in Figure
3-5.

Figure 3-5. Program Command Syntax
3-283. Command Headers
3-284. All HP-IB commands require a command header. Command headers, where possible,
consist of the full English word for the corresponding function, up to a maximum of eight
characters in length. Functions which would require more than eight characters, or more than
one word, are abbreviated. Commands which cause data to be returned to the controller
(queries) include a question mark (2) as the last character of the header.
3-285. Table 3-14 contains a summary of all the command headers for the HP 5350B/51B/528. The
table is divided into two parts: program message headers, and query headers.

3-287. Data Separators
Data separators ARE REQUIRED between headers and data, and between data fields. A
<comma> is the preferred separator, but a <space> may also be used as a separator. In the
detailed command syntax diagrams, both types of separators are represented by “ds”, as
shown above.
3-288. Command Separators
Command separators ARE REQUIRED. In the detailed command syntax diagrams, the
command separators are not shown.
NOTE
The END command separator is only sent with the last byte of the
command.
3-289. Data
3-290. Commands may have none, one, or two pieces of data sent as part of the command.
There are three types of data associated with program messages: numeric, character, and string.
Numeric data is used for function settings which require the entry of a number, while character
data is used for function settings which are notinherently numeric. Character data is also used for
binary conditions (i.e. On/Off settings). String data is used for displaying messages on the 24-
character Liquid Crystal Display on the front panel, and for sending the setup information (“SET”)
command.
3-291, Numeric Data
3-292. Numeric data applies to those functions which require the entry of a number, such as
Manual Center Frequency, Offset Frequency, Scale, and others. Numeric data entry is a “free-
format” input, with spaces allowed before and after a numeric character is entered. Spaces are
NOT allowed within a number. A decimal point and an exponent are allowed, but not required.
HP 53508/5351B/5352B
Operation and Programming
3-293. Numeric data, if required by a program message, may be entered in integer, real, or
floating point form. These numeric forms correspond to the data types (nr1, nr2, and nr3,
respectively) described in IEEE-728 Codes and Formats Guidelines. For example, the following
command strings are permitted, and are equivalent:
OUTPUT 714; MANUAL, 500000000”
OUTPUT 714; "MANUAL, 5E+08”
3-294. Program messages requiring the integer form of numeric data (for example, “RESOL” or
“DIAG”) will round any non-integer data to the nearest integer. For example, the following
command strings are permitted, and are equivalent:
QUTPUT 714; RESOL, 0.3”
OUTPUT 714;“RESOL, 1”
3-295. Figure 3-6 shows the preferred syntax for each numeric data type.

3-296. Character Data
3-297. Character data is used for those function settings which are notinherently numeric, such
as the FAST or HOLD setting for the Sample Rate function. Character data is also used for setting
binary conditions, such as the ON/OFF setting of the Smooth function. Table 3-15 lists all the
allowable character data which may be included in a command to the HP 5350B/51B/52B.

NORMAL Set FM Rate/Track function for NORMAL FM rate.
LOW Set FM Rate/Track function for LOW FM rate.
TRACK Set FM Rate/Track function for TRACK rate.
FAST Repeat measurement as quickly as possible.
HOLD Hold last measurement until new measurement is triggered.
3-298. String Data
3-299. String data is similar to character data except that the characters are enclosed in quotes.
This format allows special characters, such as <comma>, <space>, and <semicolon>, to be passed
as data. String data is used with the “DISPLAY” command for displaying messages on the front
panel LCD, and by the “SET” command to allow passing of ASCII hexidecimal characters over the
HP-IB. Refer to the descriptions of the “DISPLAY” and “SET” commands in the detailed
command descriptions beginning at paragraph 3-302.
3-300. Frequency Specifier
3-301. A frequency may be specified by an explicit number or “LASTF” (the last measurement).
All frequencies entered are in Hertz units,

Each program message and query listed is accompanied by a syntax diagram, as described in
paragraph 3-278.
3-304. All query commands return data to the controller, as discussed in the query descriptions
beginning at paragraph 3-328. Each query description includes information on the output format
resulting from a given query. Refer to paragraph 3-338, HP-1B Data Output, for a general

3-307. INIT: Instrument initialization
( INIT } 5
This program message sets the instrument to the same state as the plug-in power-up state
except that the HP-1B interface is unaffected. Errors are cleared, input and output buffers are
cleared, DUMP mode is turned off, SLEEP mode is turned off, and keyboard and display
lockouts (Diag 98,99), if active, are cleared. The “INIT” command is the only command
(other than the “DUMP OFF” command) that should be sent to the counter when DUMP
mode is enabled; any other commands will give unpredictable results.
NOTE
Since the “RESET”, “CLR”, and “INIT” commands clear the input
buffers, they should be sent so that no new input will be
handshaken in until the last command is processed. Typically,
this means the command should be sent by itself as a separate
command, as in the following HP-85 examples:
OUTPUT 714; “RESET”
OUTPUT 714; “CLR”
QUTPUT 714; “INIT”
Placing the command at the end of a string of commands, as
shown below, would have the same effect:
QUTPUT 714; “OFFSET, ON; AUTO; RESET”
OUTPUT 714; “OFFSET, ON; AUTO; CLR”

This program message is used to turn the Offset function on or off, and to set the offset
frequency. Setting the offset frequency without specifying “ON” or “OFF” turns the Offset
function ON automatically. The frequency may be positive or negative, to add or subtract
the value from the measured frequency. If “LASTF” is passed, the last measured frequency,
negated, is entered as the offset value. Frequencies entered are in Hertz units.
3-317. SCALE: Scale
This program message turns the Scale function on or off, and/or sets the value. Setting the
Scale value without specifying “ON” or “OFF” automatically turns ON the Scale function.

Most diagnostics may be set up over HP-1B using this program message. All diagnostics
except Diag 1, 41, 42, 43, 44, and 80 are available over the bus. Some diagnostics return data
over the bus, while others require an oscilloscope or additional equipment. To get a
diagnostic result over the bus, send the query DIAG? Refer to paragraph 3-344 for a
description of the diagnostic data returned to the controller.
NOTE
Diagnostic failures are not treated as errors. The Error bitin the
serial poll byte is not set.
NOTE
There are three diagnostics which cannot be exited using the
“DIAG,OFF” command. Diag 97 (IF 175 MHz Filter Adjust) can
only be exited by powering down the counter (POWER switch to
STBY). Diag 98 (Keyboard Lockout) and Diag 99 (Display Lockout)
an also be cleared by powering down the counter, or by sending
the “INIT” command.
3-321. DIAGPARM: Diagnostic Parameter
Diag 51 (Synthesizer Verification - User-Entered Frequency) requires a parameter after the
“DIAG” program message is passed. As many “DIAGPARM” program messages as
necessary may be entered immediately following the enabling of Diag 51. Refer to the

CD,
This program message allows an arbitrary string of up to 24 uppercase letters, numbers, or
punctuation to be displayed on the counter’s front panel LCD. Embedded string delimiters
are not allowed. To display a single quote, the string must be surrounded by double quotes.
To display a double quote, the string must be delimited by single quotes. Embedded spaces,
commas, and semi-colons are allowed. Periods are combined with the characters to the left,
when displayed, so they are not counted in the 24-character limit. Up to 48 characters,
including periods, will be accepted without error, but only the first 24 characters are
displayed. The remainder of the string is ignored. The string is left-justified in the display
area. Extra places are filled with blanks.
To turn off the message and return to normal display, a null (empty) string is sent. The
“INIT” command also turns off the the remote display. To blank the display, a single blank,
“7 may be sent.
The ‘DISPLAY message supersedes all others while it is enabled, thus providing “display
concealment” {equivalent to Diag 99 - Display Lockout). No measurements or error
messages will be displayed while the remotely provided string is active. !f the user goes to
Local by pressing the RESET/LOCAL key, the remote message remains displayed. To return
to the normal display, press the special key sequence 7, 4,0, RESET/LOCAL, or momentarily
disconnect the ac power to the instrument.

This program message sets the Service Request mask to cause a Service Request whenever
an enabled condition changes from 0 to Tin the Status Byte. To enable a condition, set the
corresponding bit in the Service Request Mask to “77, and to disable, set the bit to “0”, as
shown below:

Conditions may be enabled singly or in any combination desired. For example, setting
binary 0000 0110 (decimal 6) will cause a Service Request if either an error occurs or a
measurement is completed. Any number between 0 and 255 may be sent. Refer to
paragraph 3-268, Service Request Mask.
3-324. DUMP: Dump Mode
The DUMP mode provides faster reading capability. At least 100 measurements per second,
at 10 kHz resolution, may be read. When DUMP is ON, the instrument displays “DUMP-
ING---", No annunciators are displayed, and the display is not updated. (The display will
blank after 10 minutes. After DUMP is turned OFF, the display will behave normally.) Serial
poll status is not updated.
The format of the frequency returned when in DUMP mode is optimized for speed. The data
format is a 7-character numeric ASCII string, with no spaces or decimal points, of the form:
GGMMMkk ^ ЕО!
Where G = gigaHertz digits
M = megaHertz digits
k = kiloHertz digits
EOI = End or Identify
isent with last digit as message terminator)
Leading zeros are not blanked. The returned value must be multiplied by 10 kHz to get the
frequency value in Hertz.

COMMAND SYNTAX DESCRIPTIONS
NOTE
The DUMP mode will work in both Auto and Manual modes.
Before activating the DUMP mode, the instrument MUST be set
as follows:
RESOL, 4
OFFSET, OFF
SCALE, OFF
SMOOTH, OFF
If DUMP is to be used in Manual mode (using the “MANUAL”
program message), a manual center frequency may be specified
or the last measurement may be selected as the center frequency,
as described in paragraph 3-309.
In addition to the required settings listed above, there are certain
optional settings. In Auto mode, measurement speed can be
optimized by setting the counter’s FM Rate/Track function to
TRACK. The “HARMDET” command may also be used when in
Auto mode. When performing a DUMP in either mode, the
SAMPLE rate may be set to either FAST or HOLD.
When DUMP mode is ON, the only commands that should be
sent to the counter are “DUMP OFF”, “INIT”, or (if SAMPLE is set
to HOLD) the Group Execute Trigger command (example:
TRIGGER 714). Any other commands will give unpredictable
results.
3-325. SET: Instrument Setup
This program message sets up the instrument according to the data passed. The data is
determined by a previous instrument setup saved using the “SET?” query. By using the
“SET” and “SET?” commands together, different configurations may be saved, then
restored with a single command. Measurement results are not saved.

3-326. SLEEP: Disable INPUT 1 Circuit
The “SLEEP” program message disables the high frequency input (INPUT 1) by turning off
the A12 Microwave Assembly, thus minimizing the effect of having an input connected to
the counter. This mode may be useful when several instruments are connected to one
signal, and the 5350B/51B/52B is temporarily not being used for signal measurements.
INPUT 1 measurements cannot be made when the SLEEP function is on, Passing the “OFF”
parameter turns the A12 Assembly back on.
3-327. HARMDET: Harmonic Number Determination
The “HARMDET” program message allows the user to select how often the harmonic
number (N) determination occurs during measurements. In normal remote operation,
harmonic number determination takes place every 10 measurements; in local operation, it
occurs every measurement. The numeric data passed with the “HARMDET” command
causes the N determination to take place after the chosen number of measurements. If the
counter is returned to Local after the command is passed, the number of measurements set
by the “HARMDET” numeric data are lost, and the counter returns to determining the N
number every measurement (in Local}, or every 10 measurements (if the counter is returned
to Remote).
3-328. TEST?: Send Self Check Results
(TEST? } go
This query has an effect similar to pressing the SELF CHECK key on the front panel. After the
self check is performed, the pass or fail result is sent to the controller over HP-1B. The result
returned over the bus consists of 24 ASCH characters. The format is similar to the front panel
display that would appear during a local Self Check, except that no decimal points are
passed over HP-1B. (Refer to the Self Check display shown in paragraph 3-208.) If one or
more failures occur, only the first failure is caught, after which the counter exits Self Check.
3-329. DIAG?: Send Diagnostic Results

This query will cause the current diagnostic result to be sent to the controller. The result
returned over the bus consists of 24 ASCII characters, arranged in a format similar to the
front panel display that would appear during a local diagnostic, except that no decimal
points are passed over the HP-1B. Some of the displays contain measurements, such as the iF
measurement during Diag 2. These measurements may be extracted from the Pass/Fail
result by controller software. Refer to the diagnostic descriptions in Section VIII, Service.

3-338. HP-IB DATA OUTPUT
3-339. Frequency Measurements
3-340. The counter, if not in HOLD, continuously makes measurements. At the end of each
measurement cycle, the HP-1B status is checked and, if the counter is addressed to talk, the latest
measurement is sent to the interface. After the next measurement cycle, the previously sent
measurement will be overwritten if it has not been read by a controller, or otherwise handshaken
onto the bus. If the counter is not addressed to talk, no measurements are sent to the interface.
3-341. When the counterisin HOLD, no measurementis made until atriggerisreceived. After the
trigger, a single measurement will be made. This result is then sent to the interface if addressed to
talk. While waiting for the next trigger, the counter continuously checks for beingaddressed to talk
and, ifaddressed, sends the last measurement to the interface. Multiple reads of the counter bythe
controller without intermediate triggers will return the same frequency.
3-342, To read a measurement into an HP-85, execute the statement “ENTER 714: F”. This
statement will read the measurement, and convert the frequency output format into the HP-85's
internal numeric format. To preserve the counter format, read the measurement into a string:
“ENTER 714; F$”.
3-343. DUMP mode measurements use the same output method as normal frequency
measurements, except for two differences: the output formatis different (7 characters, and EOI is
sent with the last byte), and the counter cannot be in HOLD.
3-344. Diagnostic Results
3-345. Diagnostics behave similarly to measurements in that the diagnostics continuously cycle.
The data is sent to the counter’s interface at the end of a cycle after a “DIAG?” query, in a “wait
until addressed” mode. in this mode, the interface holds the data until itis read by the controller,
and will not allow the data to be overwritten by frequency measurements. The interface receives
the data regardless of whether the counter is addressed to talk or not. A “DIAG?” query must be
sent to the counter for each result desired. Diagnostic failure results are sent back in the same way
as diagnostic pass results.
3-346. Other Outputs
3-347. All other outputs must be requested by the controller throughaquery command. The data
is sent to the counter’s interface immediately, in a “wait until addressed” mode, as previously
described. Refer to the syntax for the individual query commands, beginning at paragraph 3-328,
for details on output format and content.

The decimal point is omitted if itis the last character preceding the exponent “E” in the output
string. The first digit will be zero only if the data output is zero.
The sign is “-” or <space> (implied positive}, and is placed immediately to the left of the first
digit of the mantissa. The sign may be preceded by blanks to make the total string length
constant. The returned frequency returns all significant digits. The number of significant
digits depends on the resolution to which the measurement was made.
3-350. MEASUREMENT DATA FIELD. The data field consists of 17 characters. The number begins
with the sign, followed by the digits in descending order of significance. The number is right-
justified within the data field. To keep the number of characters constant within the total string,

3-356. ERROR HANDLING
3-357. Certain conditions will produce an error in the HP 5350B/51B/52B. Refer to paragraph 3-
155 for further details on error messages.
3-358. Errors produce a static error condition. Normal operation is suspended until the error is
cleared. In the error state, the instrument processes all HP-IB commands. Errors are cleared by a
Device Clear, Selected Device Clear, the “INIT”, “RESET”, and “CLR” commands, and the
RESET/LOCAL key. (Pressing the RESET/LOCAL key will also return the counter to local
operation.) Error messages are listed in Table 3-5,
3-359. Error numbers can be read via the bus by sending the “FRR?” command. When the
"ERR?" command is received, the instrument will send the error message to the controller. The
instrument will remain in the error state. For example, the following command strings are
required to transmit the error number to the HP-85 display: |
OUTPUT 714; “ERR?”
ENTER 714:X$
DISP X$
3-360. The Status Byte (refer to paragraph 3-261) contains an error bit to flag an error condition.
When an error condition occurs, the set flag reflects the message displayed by the counter. The
error flag is cleared when the error is cleared as described previously. Note that there is a slight
delay between the “INIT” command and the clearing of the Status Byte flag. If a serial poll is
performed during this time, the Status Byte flag will still show an error.

This program sets the 5350B/51B/52B to remote, followed by commands to enable the DUMP
mode with the counter set for a Manual measurement: Manual measurement mode is selected
{with a chosen center frequency of 4 GHz), sample rate set for the fastest possible measurements,
10 kHz resolution, and all Math functions off. The DUMP mode is then turned on. The controller
enters the data from a series of measurements into 100 strings, after which the DUMP mode is
turned off. The content of each string is converted into a numeric value, multiplied by 10,000, and
printed out by the controller (in Hz units). Finally, the counter is returned to local operation.

This program illustrates the use of interrupts to detect the end of a measurement, The
53508/51B/52B sample rate is set to HOLD so that a triggered measurement may be made. The
Measurement Complete bit of the service request mask is enabled as a condition to cause a
service request. The controller is set up to call a subroutine (“Display”) to handle the service
request interrupt when it occurs. The counter is triggered and begins a measurement. A two
second wait loop is executed during which the counter completes the measurement and causes
an SRQ interrupt. The Display subroutine is called; this subroutine proceeds to read and print the
serial poll status byte and the just completed measurement. The Measurement Complete bit in
the status byte is automatically cleared after the serial poll. The subroutine sets up the controller
to accept interrupts, and then returns to the main program. When the wait loop is finished, the
counter is returned to local.

Performance Tests
SECTION IV
- PERFORMANCE TESTS
4.1. INTRODUCTION
4-2. This section contains procedures for testing the electrical performance of the HP 53508, 53518
and 5352B Microwave Frequency Counters, using the specifications listed in Table 1-7 as performance
standards. All test procedures in this section apply to all three models unless otherwise indicated.
Specifications which apply only to an individual model are indicated in the following procedures by
being enclosed in brackets, [ ]. |
4.3. OPERATION VERIFICATION
4-4. The Operation Verification procedure, beginning at paragraph 4-17, is an abbreviated series of
tests that may be performed to give a high degree of confidence thatthe instrument is operating properly
without performing the complete Performance Test. An Operation Verification should be useful for
incoming inspection, routine maintenance, and after instrument repair.
4.5. PERFORMANCE TEST
4.6. The complete Performance Test procedures begin at paragraph 4-30. All tests can be performed
without access to the inside of the instrument.
4.7. HP-1B VERIFICATION
4-8. An HP-IB verification program, described in paragraph 4-24, exercises the instrument through
the majority of its command set via the HP-IB interface. The program is written for an HP 85B as the
controller, If the instrument successfully completes all phases of the verification program, there is a
very high probability that the HP-IB interface and the counter are working properly.
4-9. EQUIPMENT REQUIRED
4-10. The equipment required for all test procedures in this section is listed in Table 1-5. Any
equipment that satisfies the required characteristics given in the table may be substituted for the
recommended models.
4-11. CALIBRATION CYCLE
4-12. The HP 5350B/518/52B requires periodic verification of operation. Depending on the use and
environmental conditions, the counter should be checked using the Operation Verification procedure
at least once every year. A full calibration procedure, including adjustments and a full Performance
Test, should be performed at least once every 6 months for instruments equipped with the standard
TCXO timebase, at least once a year for instruments equipped with the Option 001 Oven Oscillator
Timebase, and once every 5 years for instruments equipped with the Option 010 High Stability
Timebase, in order to maintain kHz accuracy of the HP 53508/51B/52B.

Performance Tests
4-13. TEST RECORD
4-14. Results of the operation verification should be recorded on a copy of the Operation Verification
Record, Table 4-3, located at the end of the procedure, Results of the Performance Tests should be
recorded on a copy of the Performance Test Record, Table 4-4, located at the end of this section.
4-15. OPTION TEST SPECIFICATIONS
4-16. The Operation Verification and Performance Tests described in this section are intended for
testing of the standard HP 53508/51B/52B. If Option 002 (Rear Panel Inputs) or Option 006 (Limiter)
is installed in the 53508 or 53518, the sensitivity specifications of the counter will be different from
the standard instrument. An HP 5350B or 5351B equipped with either, or both, options should be tested
using the same procedures as for the standard instrument, using the option specifications listed in
Section | as performance standards. Refer to Table 1-1, Specifications, and Section 111, paragraphs
3-47 and 3-49, for information on Option 002 and 006 specifications.
NOTE
The following operation verification and performance test proce-
dures require measurement of the actual input sensitivity of the
5350B/5351B/5352B. The actual sensitivity MUST be measured as
follows:
1. Before measuring, be sure to calibrate the power meter accord-
ing to the frequency calibration data provided on the power
sensor to be used in the test.
2. To measure actual sensitivity, decrease the input level to the
counter until it stops counting, then slowly increase the input
level until the counter measures the input properly (as defined
by the particular procedure being performed).

4-17. OPÉRATION VERIFICATION PROCEDURE
4-18. Power-Up Self Test
a. — Before connecting the power cord and switching on the instrument, be sure thatthe line voltage
selector is properly set, the correct fuse is installed, and all safety precautions have been
observed.
b. Setthe POWER switch tothe ON position and verify the Power-Up Self Test routine, as follows:
1. immediately after switching the power on, the counter performs a display test in
which all segments of the liquid crystal display are turned on. The display should
remain in this state for about three seconds. Check that no segments are missing.
2. ifanyofthe internal tests fail, the results of the first test failing will be displayed after
the display test. Pressing the RESET/LOCAL key will display the next test, if any,
failing. When all failing tests have been displayed, the HP-IB address will be
displayed for about two seconds. if all tests pass, the HP-1B address will be displayed
immediately after the display test.
3. After the HP-1B address is displayed, the counter should go into the measurement
mode last selected (if the counter had previously been left in Standby), or into the
Auto mode with FM Rate/Track set to NORMAL (if AC power had previously been
disconnected from the counter).
4. Ifa FAIL message is displayed during the Power-Up Self Test, refer to troubleshooting
procedures in Section VIii, Service, for information about specific diagnostic failures.
c. Enter results of the Power-Up Self Test on the Operation Verification Record (Table 4-3).
4-19. INPUT 2, Gating and Counting Check
a. Set the counter to the INPUT 2, 509 impedance mode by pressing the 500 key.
b. Connect the rear panel 10 MHZ OUT BNC to the front panel INPUT 2. Verify that the
instrument displays: 10 000 000 (+1 Hz).

4-25. The HP-85 program listed in Table 4-1 exercises the HP 5350B/51B/52B through various
operating modes via the counter’s HP-IB interface. If the counter successfully completes all phases of
the verification program, there is a high probability that the HP-18 interface (A11 Assembly) is operating
correctly. This program is not intended to be an automated test system for operation verification of the
entire counter, but rather an aid to verify that the HP-IB interface is handshaking properly, sending valid
data to the controller, and controlling the counter properly. If the HP 5350B/51B/52B does not respond
as described, refer to A11 HP-1B Interface Assembly troubleshooting in Section VII
4-26. To perform the verification, set up the HP 5350B/51B/528, HP-85B, and signal source as shown
below, The program will function with any valid HP-IB address set for the counter.

Performance Tests
4-27. The program listed in Table 4-1 may be keyed into the HP-858.
4-28. The program goes through 16 checkpoints, including a test to verify remote response at ail legal
addresses {Checkpoint 16). Atthe conclusion of each checkpoint, the operator is requested to enter the
results of the current checkpoint. These results are stored and can be printed upon completion of the
program. Table 4-2 is a sample printout of the results of the HP-IB Verification program. The printed
listing of results should be attached to the operation Verification Record (Table 4-3).
4-29. Various checkpoints throughout the program ask the operator to verify that the counter’s GATE
annunciator is on, as well as other annunciators. Note that if a signal is present at the appropriate input,
the GATE annunciator should be flashing at a rate proportional to the sample rate.
4-29a. To avoid unintentional HP-IB address change, do not interrupt power-up sequence, i.e. toggling
STBY/ON power switch of 53508/5351B/5352B.
