1-19, DESCRIPTION
1-20. The 5355A plug-in unit, when used with a 5345A Electronic Counter provides measure-
ments of CW or burst frequencies from 400 MHz to 1.6 GHz, Since the 5345A has a range of 0 to
500 MHz, the 5345A/5355A combination offers frequency measurement capability from 0—1.6
GHz, Frequencies up to 40 GHz may be measured by use of the accessories described in the
following paragraph.
1-21. For higher frequency measurements, the 5356A, 53568, or 5356C Frequency Converter
Head is used. The heads use thesingle sampler, harmonic heterodyne technique to downconvert
the input signal frequency. The 5356A allows measurements from 1.5 to 18 GHz, the 5356B allows
measurements from 1.5 to 26.5 GHz, and the 5356C allows measurements from 1.5 to 40 GHz. The
head connects to the signal source and the attached 5% foot cable connects to the multipin
connector on the front panel of the 5355A,
1-22. Signalsin the 0.4 to 1.6 GHz range are sent through a prescaler (divider) in the 5355A to the
IF circuits. Signals in the 1.5 to 40 GHz range are sent through the down-converter head to the IF
circuits. The 5355A automatically acquires the input CW or pulsed rf signal and under control of
its microprocessors algorithm, routes the down-converted signal to the 5345A mainframe to be
counted and displayed.
1-23, SERVICE EQUIPMENT AVAILABLE
1-24. A kit of extender boards is available to allow servicing printed circuit assemblies while
extended from the instrument. The extender boards allow the assemblies to be extended from
their plug-in connectors for monitoring with appropriate test equipment. The HP part number of
the kit is 05355-60100. Refer to paragraph 8-183 for detailed information.
1-25. RECOMMENDED TEST EQUIPMENT
1-26. The test equipment listed in Table 1-3 is recommended for use during performance tests,
adjustments, and troubleshooting. Substitute test equipment may be used if it meets the required
characteristics listed in the table,

etc.), If the 5355A is damaged, notify the carrier and the nearest Hewlett-Packard Sales and
Service Office immediately (offices are listed at the back of this manual). Keep the shipping
carton and packing material for the carrier’s inspection. The HP Sales and Service Office will
arrange for repair or replacement of your instrument without waiting for the claim against the
carrier to be settled.
2-5. PREPARATION FOR USE
2-6. Power Requirements
2-7. The5355A does notrequire external ac power. All necessary power is supplied by the 5345A
when the 5355A is plugged in.
2-8. Operating Environment
2-9. The operating temperature range is 0°C to 55°C, If these limits are exceeded at the
installation site, auxiliary cooling or heating should be used to keep environment within limits.
2-10. Installation
2-11, To install the 5355A, proceed as follows:
On the 5345A, set POWER switch to STANDBY.
b. Pull the locking handle on the left side of the 5355A up to the horizontal position,
c. Slide the 5355A into the 5345A. Use caution to prevent damage to interface con-
nectors at rear of unit.
d. Push locking handle down and toward the instrument until it is parallel with the front
panel,
e. For operating information, address switch settings, and connections to rear panel BNC
connectors, refer to Section II!
2-12. Compatibility with 5345A
2-13. The 5345A must be in EXT GATE mode when the 5355A is in PULSE mode and must be in
INT GATE mode when the 5355A is in CW mode. If the GATE CONTROL switch on the rear panel
of the 5345A is left in INT position, then the proper gating mode is selected automatically in
5345A's that have Serial Prefix 1808A or higher. Older 5345A's with serial prefix 1744A and below
require manual selection of EXT GATE mode (for PULSE) and INT GATE mode (for CW), However,
a minor modification can be added (see paragraph 8-13) which updates these units.

2.14, HP-IB Interconnections
2-15. HEWLETT-PACKARD INTERFACE BUS. Interconnection data concerning the rear panel
HP-IB connector is provided in Figure 2-1. This connector is compatible with the HP 10833A/B/
C/D HP-1B cables. The HP-1B system allows interconnection of up to 15 (including the controller)
HP-IB compatible instruments. The HP-18 cables have ¡dentical “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 fromthe calculator (or other 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 great 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. ’
2-16. CABLE LENGTH RESTRICTIONS. To achieve design performance with the HP-IB, proper
voltage levels and timing relationship must be maintained. If the system cable is too long, the
lines cannot be driven properly and the system will fail to perform properiy. 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. The total cable length for the system must be equal to or lessthan 2 metres (6.6 feet) times
the total number of devices connected to the bus.
c. The total number of instruments connected to the bus must not exceed 15.
2.17, 5355A Listen Address
2.18. The 5355A contains a rear panel HP-1B instrument address selection switch. There are five
switches designated (As, Ад, Аз, А2, Ач) which are used to select the address. Instructions for
setting and changing the listen address are provided in Section 11 of this manual along with
programming codes.
2.19. HP-IB Descriptions
2-20. A description of the HP-1B is provided in Section 111 of this manual. A study of this infor-
mation is necessary if the user is not familiar with the HP-IB concept. Additional information
concerning the design criteria and operation of the bus is available in IEEE Standard 488-1975,
titled “IEEE Standard Digital Interface for Programmable Instrumentation”.
2-21. Operational Check
2-22. To determine if the instrument is operating properly, refer to the performance check in
Section IV. Contact the nearest HP Sales and Service Office (see manual back cover) for infor-
mation relative to warranty claims. |
2-23. PACKAGING FOR RESHIPMENT
2-24. Original Packaging
2-25. The same containers and materials used in factory packing can be obtained through the
Hewlett-Packard Sales and Service Offices listed at the rear of this manual.
2.26. If the instrument is being returned to Hewlett-Packard for service, attach a tag indicating
the type of service required, return address, model number, and full serial number. Mark the
container FRAGILE to assure careful handling.
Model 5355A
installation
2-27. In any correspondence refer to the instrument by model number and full serial
number.
2-28. Other Packaging Methods
2.29. If it becomes necessary to reship an instrument, good commercial packing should be
used. Contract packaging companies in many cities can provide dependable custom packaging
on short notice. The following general instructions should be followed when repackaging with
commercially available materials.
a. If shipping to a Hewlett-Packard Office or Center, attach a tag indicating the type of
service required, return address, model number, and full serial number.
b. Wrap the instrument in heavy paper or plastic,
c. Use a strong shipping container. A double-wall carton made of 350-pound test material is
adequate.
d. Use enough shock-absorbing material (3- to 4-inch layer) around all sides of the instru-
ment to provide a firm cushion and prevent movementinside the container. Protect the
control panel with cardboard.
e. Seal the shipping container securely.
f. Mark the shipping container FRAGILE to assure careful handling.
2-30. STORAGE
2-31. If the instrument is to be stored for an extended period of time, it should be enclosed in a
clean, sealed container.

SECTION III
OPERATION AND PROGRAMMING
3-1, INTRODUCTION
3-2. This section contains descriptions of operating characteristics and modes, operating
procedures, descriptions of front and rear panel controls and indicators, keyboard test
procedures, and Hewlett-Packard Interface Bus (HP-1B) programming information.
3-3. The 5355A is a plug-in for the 5345A Electronic Counter. Operating and programming
characteristics of the 5345A must be understood before attempting to operate and program the
5355A, For complete information on the 5345A, refer to the 5345A Operating and Service Manual.
When appropriate, the 5355A programming explanations that follow contain notes on the
interrelated 5345A programming instructions.
3-4. The 5355A is programmed via the HP-1B. The HP-1B is a carefully defined instrumentation
interface which simplifies the integration of instruments, calculators, and computers into
systems. The HP-1B is Hewlett-Packard's implementation of ¡EEE Standard 488-1975, “Standard
Digital Interface for Programmable Instrumentation”.
3-5. OPERATING CHARACTERISTICS
3-6. The following paragraphs describe the operating ranges and modes, AM and FM tolerance
and automatic amplitude discrimination.
3-7. Operating Ranges
3-8. The two operating ranges are 0.4 to 1.6 GHz and 1.5 to 40 GHz. Frequencies in the lower
range are measured by use of a prescaler technique while frequencies in the higher range are
measured by use of a harmonic heterodyne down-conversion technique. A separate front panel
input connector is provided for each range (see Figure 3-7). Selection of the two ranges is

the 0.4—1.6 GHz input (BNC) is routed to the prescaler. When the key indicator is not
lit, the RF HEAD INPUT (multipin connector) is sent to the IF circuits. The multipin connector
input requires the use of the 5356A/B/C Frequency Converter Head. The 5356A covers the
range of 1.5 to 18 GHz, the 5356B covers 1.5 to 26.5 GHz, and the 5356C covers 1.5 to 40 GHz, See

3-25. The LISTENING indicator on the front panel, when illuminated, indicates the 5355A is
addressed and monitoring the interface bus.
3-26. AM Tolerance
3-27. The 5355A/5345A will measure carrier frequencies containing amplitude modulation to
any modulation index provided the minimum voltage of the signal is greater than the sensitivity
specification of the 5355A.
3-28. FM Tolerance
3-29. The 5355A/5345A will measure carrier frequencies which are modulated in frequency
such as a microwave radio carrier. The FM tolerance is the worst case FM deviation which can be
present without affecting the counters ability to acquire the signal. If the deviations about the
carrier are symmetrical, then the counter averages out the deviations to measure the actual
carrier frequency, The FM tolerance is determined by the mode of operation. See Table 1-1, The
auto mode provides FM tolerance of 15 MHz peak-to-peak. A special FM mode is selected by
il purses
LIMITES
simultaneousiy (in CW auto mode), The special FM mode
provides a tolerance of 60 MHz peak-to-peak but results in slower acquisition time (1,1 second
compared to 400 milliseconds for CW position).
NOTE
Most measurements should be made without using the special
FM mode, The special FM mode should be used only when the
input signal has significant amounts of FM (>15 MHz p-p).
3-30. Automatic Amplitude Discrimination (CW Mode)
3-31. The automatic amplitude discrimination feature allows the 5355A to acquire and display
the highest level signal within its sensitivity range. The highest level signal must be 8 dB greater in
ой amplitude than any other signal present within 500 MHz and 20 dB greater than any signal over
the full range. This feature is useful for discriminating against spurious signals and harmonics.

3-60. The capability of a device connected to the HP-IB is specified by the interface functions
that it has. Table 3-6 lists the interface functions included in the 5355A. The “Interface Function
Subset Identifier” refers to the particular capability of the interface function as listed in
Appendix C of IEEE Standard 488-1975,

NOTE: Interface functions provide the means for a device to receive,
process and send messages over the bus.
3-61. Bus messages are of 12 types. Table 3-7 lists each bus message, a brief description of the
message, and the response of the 5355A/5345A to the message. The last column shows typical
examples of how to send/receive each message using the 9825A computing controller, For
complete details on sending bus messages using the 9825A refer to the “9825A Extended 1/0

3-63. The 5355A must be assigned a bus address, Table 3-8 gives the allowable address switch
settings. The setting of switches A1 through As defines the addresses. The listen address
(Table 3-8) is used to program the functions of the 5355A,
3-64, Before learning the programming details of the 5355A, some knowledge of 5345A
programming is required, as described below,
3-65. Programming the 5355A/5345A
3-66. The 5355A is programmed for remote control of all its operating modes by the codes
shown in Table 3-9. The 5355A operates remotely only in the listen function and does notoutput
to the HP-IB.
3-67. Measurement data from the 5355A is sent to the 5345A for processing and display. This
information is sent to the HP-IB via the talk output of the 5345A which must be programmed by
the codes shown in the 5345A Operating and Service Manual, except as described in paragraph
3-68 below.
NOTE
5345A program codes E9 and JT are invalid when the
5355A is plugged in, as detailed in the following
paragraph, |
3-68. INVALID 5345A PROGRAM CODES. The 5345A program codes E9 (Sample Rate Hold)
and J1 (Sample Trigger Command) are invalid when the 5355A is plugged into the 5345A. These
functions are performed by programming the 5355A plug-in using the Hold code, i.e., HD9
selects the 5345A Sample Rate and HD1 is used in place of the normal 5345A code E9 for Sample
Rate Hold. (Refer to Table 3-9),
NOTE
When the 5345A is operating in remote control, the
rear panel GATE CONTROL INPUT switch function
must be programmed according to the operating
mode of the 5355A. The 5345A must be programmed
for External Gate (E;) when the 5355A is in the pulse
mode of operation. The 5345A must be programmed
for Internal Gate (E3) when the 5355A is in the CW
mode of operation.
3-69. Status Display
3-70. The status of the 5355A operation is shown on the display of the 5345A when program
code R {Read Status) is sent to the 5355A. The display contains a digit in each position that
indicates the mode of operation (first 8 digits) the head code (9th digit) and the error code or
diagnostic mode (10th and 11th digits) as illustrated in Table 3-70. The head code indicates which
Frequency Converter Head is installed. The error codes are described in paragraph 3-54.
Diagnostic modes are described in Table 3-11.
