SAFETY INFORMATION
WARNING |
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. (Grounding one
conductor of a two conductor outlet is not sufficient protection.)
Whenever it is likely that the protection has been impaired, the instrument must be made inoperative and be sacured
against any unintended operation.
If this instrument is to be energized via an autotransformer (for voltage reduction) make sure the common terminal is
connected to the earthed pole terminal {neutral} of the power source.
Instructions for adjustments while covers are removed and for servicing are for use by service-trained personnel only.
To avoid dangerous electric shock, do not perform such adjustments or servicing unless qualified to do so.
For continued protection against fire, replace the fine fuse(s) only with 250V fuse(s) of the same current rating and
type (for example, normal blow, time delay). Do not use repaired fuses or short-circuited fuseholders.
When measuring power line signals, be extremely careful and always use a step-down isolation transformer whose
output voltage is compatible with the input measurement capabilities of this product, This products front and rear
panels are typically at earth ground, so NEVER TRY TO MEASURE AC POWER LINE SIGNALS WITHOUT AN
ISOLATION TRANSFORMER.

Before connecting the instrument to ac power lines, be sure that
the voltage selector is properly positioned as described below.
2-9. The HP 5316B is equipped with a power connector module that has a plug-in printed-circuit
card line voltage selector to choose 100-, 120-, 220-, or 240-volt ac operation (see Figure 2-1).
Before applying power, the selector card musts 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 card in the module. When
the card is plugged into the module, the only visible markings on the card indicate the line voltage
to be used. The correct value of line fuse, with 250-volt rating, must be installed after the card is
inserted.
2-11. To convert from one line voltage to another, the power cord must be disconnected from the
power module before the sliding window covering the fuse and card compartment can be moved to
expose the fuse and circuit card.
2-12. Pull on the fuse lever to remove the fuse and then pull the card out of the module. The fuse
lever must be held to one side to remove and insert the card. Insert the card so the marking that
agrees with the line voltage to be used is visible.
2-13. Return fuse lever to normal position, insert correct fuse, slide plastic window over the
compartment, and connect the power cord to complete the conversion.

SECTION i
OPERATION
3-1. INTRODUCTION
3-2. This section provides operating information for the HP 5316B Universal Counter. Descriptions of
all front panel controls, connectors, and indicators, as well as an operator's check, operating
instructions, and operators maintenance, are provided.
3-3. OPERATING CHARACTERISTICS
3-4. The HP 5316B is a 100 MHz/100 ns full universal counter, capable of Frequency, Period, Time
Interval, Ratio, and Totalize measurements. To maximize resolution, the HP 5316B uses a reciprocal
counting technique for frequencies below 10 MHz, automatically switching to conventional frequency
counting for frequencies above 10 MHz. The gate time is continuously adjustable from 60 ms to 10s, via
the front panel. The internal microprocessor performs the calculations, and automatically takes into
account the selected gate time. The display is given in engineering notation {i.e., exponents of blank,
+3, 16, or £9, except in totalize modes). The input amplifiers are optimized for both time interval and
frequency measurements. In addition, the HP 5316B may be programmed via the HP-IB. The rear panel
external reference input can accept 1, 5, or 10 MHz as the reference due to a time base multiplier
(injection-lock-multiplier). With the addition of Option 801 TCXO or Option 004 Oven Oscillator,
increased temperature stability is gained, and this increased stability allows extended calibration
periods. -
3-5. When Option 003 Channel C is installed, the frequency counting range of the counter is
extended to 1 GHz. Signals on Input C are prescaled by 10, then routed to the Channel C input of the
MRC (Multiple Register Counter) integrated circuit on the HP 5316B motherboard. The input
sensitivity can be decreased, continuously, up to 20 dB nominally (in the range of 50 to 500 MHz) and 10
dB nominally (in the range of 500 to 1000 MHz).
3-6. MODES OF OPERATION
3-7. The HP 5316B provides 10 modes of operation and two CHECK functions. The resolution and
accuracy for each mode except A Armed by B is provided in Table 1-1. The modes of operation are
described in the following paragraphs:
FREQA A BY B (Gated Totalize)
PERA FREQ A ARMED BY B
TI. AB FREQ C (Option 003)
TA AVG. Â-B TOT (Manual Totalize START/STOP)
T.I. DELAY (Holdoff) CHECK
RATIO A/B Display Check
3-8. FREQ A
3-9. Frequency measurements are made by connecting a signal (up to 100 MHz) to INPUT A, and
pressing the FREQ A function (with the Blue Shift key OUT). Select the appropriate input signal
conditioning and adjust the LEVEL/SENS control (with TRIGGER LEVEL /SENSITIVITY key to TRIGGER
LEVEL) to the optimum trigger point. The optimum trigger point may be determined by centering the
LEVEL/SENS control within the triggering range, and triggering is indicated by the flashing TRIGGER -
light. The actual trigger voltage may be determined by monitoring the TRIGGER LEVEL OUT on the
front panel. The voltage at these points will be within +5% +15 mV of the actual trigger voltage overa
+2.0 volt range. The GATE TIME control determines the resolution of the measurement, and may be

displayed by pressing the GATE TIME function key and Blue Shift key. The gate time range when FREQ
À is pressed is 60 ms to 10's, typical. However a gate time range of 500 us to 30 ms is available by pressing
T.1. DELAY and TOT STOP/START simultaneously. When the Blue Shift key is QUT, the HP 5316B will be
in FREQ A. When the Blue Shift key is IN, the HP 5316B will be in PER A. PER A is discussed in the
following paragraph.
3-10. PER À
3-11. The Period À mode allows signal period measurements to be made over a range of 105s to 10 ns
into INPUT À. Select the appropriate input signal conditioning, and Trigger Level/Sensitivity. The gate
time range is 60 ms to 10 s, typical, when PER A is pressed. However, a shorter gate time is also available
for PER A (500 us to 30 ms) as described in FREQ A, paragraph 3-9.
3-12. ТА. А-В
3-13. T.I. A—B measures the time interval between a START signal at INPUT A and a STOP signal at
INPUT B. If both the START and STOP signals are derived from the same signal, connect the signal to
INPUT A and set the SEP/COM A key to the COM A position (IN). Separate Slope and Level/Sensitivity
controls for each channel allow variable triggering on either positive or negative going slope. A single-
shot time interval measurement may be made over a range of 100 ns to 105 s.
3-14, TA. AVG A—B
3-15. The T.l. Average mode provides greater resolution of time interval measurements than single-
shot T.I. mode provides. In the T.l. AVG mode, the gate time control varies the number of events of
time intervals averaged (approximately GATE TIME X REP RATE). The resolution of the measurement is
improved by the \/N, where N is the number of time intervals averaged. A limited range of negative
T.i. measurements (ie, B triggers before A} are possible in T1. AVG mode.
3-16. Inthe T.L AVG mode, there must be at least 200 ns dead time, Dead time is the time between the
preceding time interval stop event and the current time interval start event, as shown in Figure 3-1. This
means that in T.I. AVG mode, the repetition rate must be less than 5 MHz. Also time interval averaging
of high stability (synthesized) sources is not recommended because the displayed result may not be
accurate. Proper averaging requires that there be no coherence between the source and the counter
time base oscillator.

3-18. The T.i, DELAY mode of operation is similar to T.I. A—B, but with the following additional
control: The front panel GATE TIME control inserts a variable delay (from 500 us to 30 ms nominal)
between the START (INPUT A) event and the enabling of the STOP (INPUT B) event. Potential
STOP events are ignored during the specified delay or holdoff. The amount of delay time may be
continuously measured and displayed by simultaneously pressing the T.l. A—B, T.I. DELAY, and
Blue Shift keys. Figure 3-2 illustrates the T.I. BELAY function. It should be noted that both START
and STOP Slopes are positive in this illustration.

3-19. RATIO A/B
3-20. The RATIO A/B mode of operation measures and displays the frequency ratio of signals on
INPUT A tosignals on INPUT B. The GATE TIME control determines the resolution by selecting the
number of cycles of the INPUT B signal over which the ratio A/B is measured. Increasing the gate
time (towards MAX) or increasing the frequency of INPUT A results in an increased resolution of
the measurement. Frequencies up to 100 MHz are allowed on both channels.
3-21. ABYB

3-23. A ARMED BY B
3-24, The HP 5316B has a measurement function, Frequency A, Averaged, Armed By B, for frequency
averaging. Called “A ARMED BY B”, this function allows the HP 5316B to average together multiple
frequency measurements, To do this a sampling signal synchronized with and of pulse width less than
the frequency bursts must be applied to the Channel B input. This signal performs two functions: one, it
tells the the HP 5316B when to count the incoming bursts and when to ignore the dead time between
bursts; and two, it opens the HP 53168 gate, The measurement interval is set from the front panel and its
length determines the number of bursts to be averaged. Figure 3-4 shows an example of function A
Armed By B. In this example, TMHz bursts, 10 us wide, ata 10 kHz repetition rate are applied to Channel
A input. A sampling signal of equal repetition rate and shorter pulse width is applied to Channel B. This
sampling signal must be synchronized with the Channel A frequency burst signal. When the first burst
occurs, the sampling signal at Channel B opens the gate, and tells the HP 5316B to begin counting the
events at Channel A. When the sampling signal disappears, the HP 5316B stops counting the events at
Channel A. If the gate is still open and another burst occurs, the HP 5316B will add these “new” events to
the previous events counted. This will continue until the measurement interval runs out, On the next
sampling pulse, after the gate closes, the HP 5316B will compute the average frequency of the signal
during the burst (in this example 1 MHz). A final sampling pulse must occur after the measurement
interval ends to terminate the measurement. The events that occurred during this final pulse are not
averaged in,
3-25. The length of the measurement interval and signal repetition rate determine how many bursts
will be averaged. Faster burst repetition rates allow shorter measurement intervals for a given number
of averages. The main limit is that no more than 100 million “events” can be counted (either input
frequency cycles or time base counts). in the case of Figure 3-4, each burst contains 10 “events”, with 10

thousand occurring in 1 second for 100 thousand “events” per second. Since 100 million events is the
limit, the HP 5316B could average for 1000 seconds before the events counter would overflow. And,
since the measurement interval determines the number of averages, a 1000-second measurement
interval would be necessary before the events count or time base count would overflow. This, of
course, is longer than that obtainable from the HP 5316B (maximum measurement interval of ~10
seconds). A specific case where the HP 53168 would overflow would be a 50 MHz signal pulsed for 200
ns at a 2 MHz rate. In this case 10 “events” occur during each burst, with 2 million bursts persecond, or
20 million “events” in 1-second. So, the HP 5316B would overfiow in 5 seconds, thus the gate time must
be less than 5 seconds, and 10 million bursts would be averaged, If the 100 miltion events límit is
exceeded the displayed answer will be inaccurate.
3-26. A ARMED BY B has two modes (two different measurement interval ranges) and is not labeled
on the front panel. For a measurement interval range of 500 us-30 ms, press T.I, DELAY and RATIO A/B
together. The measurement interval may be displayed by selecting the GATE TIME mode for the LONG
interval or by pressing T.i. A-B, T.I. DELAY, and Blue Shift key simultaneously for the SHORT interval.
For a measurement interval range of 60 ms to 10 seconds, press FREQ A and TOT STOP together. The
Channel A Trigger Slope is set by the front panel Channel A Slope switch, The sampling signal enable
siope (begin counting) is determined by the Blue Shift key. In the QUT position the counting will be
enabled on the sampling signal positive slope. In the IN position, the counting will be enabled on the
sampling signal negative slope. The gate will also be opened on the same slope as determined by the
Blue Shift key. The disable slope is determined by the Channel B front panel slope switch. The
measurement interval is controlled, as normal, by the front panel GATE TIME control. The gate will
close once the selected time has passed. There is no problem if the gate should close in the middle of
counting a burst. The following limits do exist in this mode.
4. 200 ns minimum dead time between bursts,
2. 100 ns minimum burst width. |
3. The enable slope can only be negative when using the short measurement interval (500 us-30
ms), but can be positive or negative when under remote control.

3-27. FREQ € (Option 003)
3-28. To make a frequency measurement on a CW signal in the range of 50 MHz to 1 GHz, select
FREQ C function and apply the signal to INPUT С.
| CAUTION |
Make sure that the amplitude of the signal does not exceed the 1V
rms dynamic range.
Set the GATE TIME control to MIN (but not hoidi. Set the SENS C control to MIN. Slowly move the SENS
C control in a clockwise direction {toward MAX) until the counter begins to gate. This represents the
optimum trigger sensitivity. To increase the displayed resolution, move the GATE TIME control toward
MAX,
NOTE
The Trigger Lights for INPUT A and INPUT B are inoperative and
extinguished when functions FREQ C or GATE TIME are selected.
This is normal. However pressing either Channel A or B Slope
switches will reset the counter.
3-23. TOT STOP/START
3-30. Totalize STOP/START is a manually gated, Totalize mode of operation. Pressing the Blue Shift
key (IN position) opens the main gate, allowing INPUT A events to be counted. Pressing the Blue Shift
key again (OUT position) closes the gate, stopping the count. The count is continuously displayed, and
cumulative from gate cycle to gate cycle. The RESET button clears the counter and resets the display to
zero.

Multiple Register Counter (MRC). It is used to verify the basic operation ofthe counter, GATE light and
GATE TIME control.

3-37. FUNCTION SELECTION CONTROLS
3-38. The function selection controls section of the front panel contains the POWER (STBY/ ON), and
RESET/LOCAL keys, the “Function” keys group (within the border outline} and Gate Time/Delay
control.
3-39. The POWER key sets the HP 5316B either to ON or STBY (standby). In the ON position (IN)
power is supplied to the entire instrument. In the STBY position (QUT) the unregulated voltages are
disconnected from the power supply voltage regulators. The RESET/LOCAL key clears and updates the

Remote Programming via the HP-1B paragraph 3-73.
3-40. Each of the keys within the outlined function group can select one of two functions, as follows:
With the Blue Shift key in the “OUT” position, the keys select the function labeled above (e.g., FREQ A,
TL A-—B, etc). With the Blue Shift key in the IN position, the keys select the function labeled in blue
below (e.g., PER À, T.l. AVG A-+B, etc.).
3-41. The GATE TIME/DELAY control determines the amount of gate time per measurement,
continuously adjustable over a range of 60 ms to 10 s. The selected gate time may be displayed by
pressing the GATE TIME function key, and the Blue Shift keys. In the T.I. DELAY mode of operation, the
control determines the amount of time the start channel is held off or “delayed” (see paragraph 3-17).
The amount of “delay” may be displayed by pressing the T.I. AB, T.l. DELAY, and Blue Shift key
simultaneously. In the T.I. A-B mode of operation, the GATE TIME/DELAY control determines the
“sample rate”.

3-42. SIGNAL CONDITIONING CONTROLS
3-43. A full complement of signal conditioning controls are provided for each channel (A and B} input
(see Figure 3-6), These controls allow the selection of Attenuation (X71, X20}, Slope (positive or negative)
and input coupling (AC or DC), The SEP/COM A switch allows the selection of separate Channel A and
B input in the SEP position. The COM A position disconnects the Channel B Input BNC, and connects
both Channel A and Channel B input amplifiers to the Channel A input.
3-44. A low pass filter for Channel A input is provided. With the FILTER NORM key in the 100 kHz (IN)
position, frequencies above 100 kHz are effectively attenuated. With the FILTER NORM key in the
Normal (OUT) position there is no effect,
3-45. TRIGGER LEVEL/SENSITIVITY CONTROLS
3-46. The Trigger Level/Sensitivity controls provided for each channel operate as follows: With the
TRIGGER LEVEL/SENSITIVITY key in the “OUT” position, the LEVEL/SENS control adjusts the trigger
level, (over a range of 2.5 volts dc in ATTN X1, or +50 volts dc in ATTN X20). With the TRIGGER
LEVEL/SENSITIVITY key in the “IN” position, the LEVEL/SENS control adjusts the input sensitivity from
MAX {10 mV up to 10 MHz, 25 mV up to 100 MHz; with control fully clockwise to MIN (greater than 500
mV) with control fully counterclockwise (see Figure 3-5). The trigger levels may be monitored at the
front panel TRIGGER LEVEL jacks. The voltage at this point is 45% £15 mV of the actual voltage over the
range of +2.0Y,

Operation
3-54. During this cycle, the microprocessor performs a check sum of the internal program in ROM
and a bit pattern is written into RAM. Then it performs a partial check of the MRC and 1/0 ports, and
performs a link test between the microprocessors. Any failure during the cycle will produce a
numbered error (for a U7 microprocessor, MRC or 1/0 failure), or a flashing of the HP-IB status LEDs
(for a microprocessor link test failure). If a numbered error occurs, the ERROR LED will remain lit. Refer
to Error Messages, paragraph 3-59. If the HP 5316B is placed into STANDBY and then immediately
placed in ON again, the display will illuminate random segments during the power- up cycle, This is
normal,
3-55. MEASUREMENT PROCEDURES
3-56. Figures 3-13 through 3-27 show general operating procedures with the HP Model HP 53168
Universal Counter in typical measurement setups, Description numbers match the locator illustrations.
The following paragraphs provide recommended operating guidelines, to assist in making the most
accurate measurement possible,
3-57. Frequency, Period, and Ratio Measurements
1. For cw sine wave or symmetrical waveforms ( (triangle, square, etc.) use ac coupling and the
sensitivity mode,
2. For asymmetrical waveforms (pulse trains, TTL, ECL signals, ramps, etc.) use a combination
of dc coupling, Trigger Level, and fixed attenuator. AC coupling these types of signals tends to
distort them slightly, due to the charging of the capacitor. More important, the position of the
signal on the zero preset trigger level is determined by the average dc level of the input.
Depending on the pulse width and duty cycle, this dc average may be low enough to allow the
base line noise to trigger the counter, producing false counts (see Figure 3-7). DC coupling
tixes the dc level of the input signal, which allows the adjustable Trigger Level to be positioned
at the optimum point. Set the Trigger Level control to the approximate center of the triggering
range indicated by the trigger light (see Figure 3-8) The actual dc trigger level may be
monitored at the front panel test point. When programming via the HP-IB, it may be set
directly. |
Oe Е STE RESIS BAND
Figure 3-7. AC Coupled Measurements
3. When input loading is a problem (i.e., 1 MO load or cable capacitance) or when a more con-
venient method of probing is desirable, use a 10:1 oscilloscope probe. A probe is
recommended for ali logic applications.
4. For sine wave measurements <100 kHz, always use the low pass filter, selectable on the front
panel. Normally the input signal is integrated over the entire 100 MHz bandwidth. Use of the
Filter effectively removes noise and harmonics (above 100 kHz), that may affect the correct
measurement.
3-11
HP 53168
Operation
— | HYSTERESIS BAND
Figure 3-8. DC Coupled Measurements
Be very careful with input levels at higher frequencies (greater than 5 MHz). The counter front
end is protected to 6 volts rms at these frequencies.
WARNING |
WHEN MEASURING POWER LINE FREQUENCIES, BE EXTREMELY CARE-
FUL AND ALWAYS USE A STEP-DOWN ISOLATION TRANSFORMER
(WITH =10V OUTPUT). THE COUNTER’S PANEL IS TYPICALLY AT
SIGNAL GROUND, SO NEVER TRY TO MEASURE THE 50 OR 60 Hz LINE
WITHOUT AN ISOLATION TRANSFORMER.
3-58. Time interval Measurements
To insure waveform fidelity during T.I. measurements, always use dc coupling.
Measurements of pulse width, and time between pulses, are more conveniently made in the
COM A (common) position. | |
T.1. Average measurements of high stability (synthesized) sources are not recommended
The displayed result may not be accurate. Proper averaging requires that there be no
coherence between the source and the counter time base oscillator. (See Application Note
162-1, Time Interval Averaging.)
in general, use the GATE TIME control to vary the amount of resolution displayed. This con-
trol does not affect accuracy. It basically trades off longer measurement time for more
resolution,
3-59. TROUBLESHOOTING/ERROR MESSAGES
3-60. Two different type error messages exist in the HP 5316B. First is the numbered errors. Failures in
the power-up self-check will result in the momentary display of one of these messages. The ERROR
LED will remain on until the error is cleared and the instrument reset. The three error messages are:
ERROR MESSAGE
ET ies Possible failure in microprocessor ATU?
PAS Possible failure in 1/O ports
ES is Possible failure in A1U2 (MRC); rear panel oscillator switch in the
EXT position with no external signal; or a failure in the À7 oscil-
lator assembly.
If the ERROR annunciator is lit, verify the error number (1, 2, or 3) by repeating the power-up self-
check, and refer to Section VIII, Troubleshooting. Power-up self-check is initiated when the POWER
switch is placed from STBY to ON.
3-12
HP 53168
Operation
3-61. The two HP-IB status annunciators indicate a failure in the following ways:
Flashing in-phase ........... Possible failure in the HP-IB microprocessor ATU10.
Flashing out-of-phase ....... Possible link failure or defective HP-IB microprocessor.
if one of these failures occur when the POWER switch is placed in ON from STBY, refer to Section Vill,
Troubleshooting.
3-62. OPTIONS
3-63. The operating characteristics of the HP 5316B are affected by the addition of any of the options
described in the following paragraphs.
3-64. Time Base Options
3-65. Option 001 provides a Temperature Compensated Crystal Oscillator (TCXO) which results in
higher accuracy. The TCXO is a 10 MHz oscillator, capable of making minor frequency corrections to
compensate for offsets due to temperature variations. Option 004 Oven Oscillator provides increased
temperature stability and accuracy over Option 001. See Table 1-1 for complete specifications of
Options 001 and 004.
3-66. Channel C Option 003
3-67. Option 003 extends the frequency counting range of the HP 53168 from 100 MHz (in Channel A)
to 1 GHz (in Channel C). The input sensitivity and gate time are adjustable via front panel controls. See
Table 71-1 for complete specifications of Option 003. |
3-68. OPERATOR'S MAINTENANCE
3-69. The only maintenance the operator should normally perform is the replacement of the primary
power fuse. This fuse is located within the Line Module Assembly. For instructions on how to change
the fuse, refer to paragraph 2-8, Line Voltage Selection. |
FT a a а о, а
ii EEE
+
4
4
LE асы
Make sure that only fuses with the required rated current and of the
slow-biow type are used for replacement. The use of repaired fuses
and the short-circuiting of fuse-holders must be avoided.
3-70. When Option 003 Channel C is installed, the operator may be required to replace the input
BNC fuse (HP P/N 2110-0301). This is located within the INPUT C BNC connector (See Figure 3-9
for details). To replace the fuse, disconnect the power cord, unscrew the special BNC barrel and,
with needle-nose pliers, remove and replace the fuse. Reinstall the BNC barrel, and tighten using a
BNC cable connector. Be careful not to overtighten.

3-73. REMOTE PROGRAMMING VIA THE HP-IB
3-74. Introduction
3-75. The HP 5316B Universal Counter is compatible with the Hewlett-Packard Interface Bus (HP-IB).
Remote programming is installed as standard equipment and allows the counter to respond to remote
control instructions and to output measurement data via the HP-IB. At the simplest level, with no
system controller, the HP 5316B can output data, in the talk only mode, to other devices such as a
printer or a digital-to-analog converter. In more sophisticated systems, a computing or other type of
controller can remotely program the HP 5316B to perform a specific type of measurement, trigger the
measurement, and output the results.
NOTE
HP-1B is Hewlett-Packard's implementation of IEEE Std. 488-1978,
“Standard Digital Interface for Programmable Instrumentation”.
3-76. The operator must be familiar with the selected controller, the HP-1B, and the manual operation
and functional capabilities of the HP 5316B. The following HP manuals should provide useful
background information:
HP-85 Owners Manual and Programming Guide (P/N 00085-90002)
Condensed Description of the Hewlett-Packard Interface Bus (P/N 59401-90030)
HP-1B Programming Hints For Selected Instruments (P/N 59300-90005)
3-77. BUS COMPATIBILITY
3-78. Interface Function
3-79. The capability of a device connected to the bus is specified by its interface functions. These
functions provide the means for a device to receive, process, and send messages over the bus. Table 3-2
lists the HP 5316B interface functions using the terminology of the IEEE 488-1978 standard. These
functions are also listed below the rear panel HP-IB connector, as follows:
SH1, AH1, T1, L2, SRT, RL1, PPg, DCT, DT1, Co
The number following the interface function code indicates the particular capability of that function.
Table 3-2. HP-1B Interface Functions

Operation
3-80. The HP 5316B operates {as listed in Table 3-2} as both a talker and listener. The HP 5316B output
format is the same regardless of the mode (talk only/addressabie.
d.
3-81.
TALK: The HP 5316B can be addressed to Talk by a controller or by the TALK ONLY switch for
use in system without a controller. When addressed as a Talker, the HP 5316B will send data out
to other devices on the bus, This data is the result of a measurement in progress when
addressed, or the next measurement, depending on the function selected. The Talk Only
witch and the HP-1B address switches are located on the rear panel. (See Figure 3-11).
NOTE
To remove the HP 5316B from the TALK ONLY mode, set the
ADDRESSABLE/ TALK ONLY witch to ADDRESSABLE and press
RESET (front paneli. When RESET is pressed the HP 5316B will exit the
TALK ONLY mode.
LISTEN: When addressed as a Listener, the instrument can accept any number of commands
from the controller via the bus. These commands are used to program the instrument
operation.
SERVICE REQUEST SRQ:: SRQ can be sent active on the bus at the end of the measurement.
The HP 5316B has the capability to request service asynchronously from the controller in
charge of the bus. See “SR” described in Binary Command section, paragraph 3-91.
REMOTE/LOCAL: Normally the HP 5316B is under front panel (local) control. in order to
program the HP 53168, it must be placed into Remote. Once in Remote, the programmable
functions cannot be affected by front panel control, except the RESET/LOCAL key, which may
he used manually to return the HP 53168 to local control, The RESET/LOCAL key may be
disabled with Local-Lockout (LLO In LLO, the bus command GTL (Go To Local) must be sent
to disable LLO.
PARALLEL POLL: The HP 5316B does not respond to a paraliel poll.
DEVICE CLEAR: When a group or selected device clear is received, the instrument resets and
makes a new measurement.
DEVICE TRIGGER: When a device trigger is received, the HP 53168 will reset and make anew
measurement.
CONTROLLER: The HP 5316B cannot act as a controller.
BUS MESSAGES
3-82. Through bus messages, devices on the bus can exchange control and measurement infor-
mation. There are 12 basic messages which can be sent over the interface. Table 3-3 lists each bus
message, giving a description of the HP 53168 response, and examples of the various controliers imple-
mentations of the messages.

Operation
3-83. Address Selection
3-84. To use the HP 5316B in an HP-1B system, first set the rear panel address switches to the desired
address. The leftmost switch sets the counter to the ADDRESSABLE mode or the TALK ONLY mode.
The ADDRESSABLE mode is used whenever a calculator or other controller is used within the system.
TALK ONLY mode is used when the counter is operating under its own control (no controller on bus)
and sends its measured result to another device on the bus, such as a printer set to LISTEN ALWAYS, 0
3-85. The five rightmost switches, As through A 1, set the TALK and LISTEN addresses of the HP 53168
when it is used in the ADDRESSABLE mode. Table 3-4 shows all possible address settings and the и
corresponding ASCII codes for talk and listen. The HP 5316B is factory set to address 20 as shown in Е
Figure 3-22.
L.. ADDRESSABLE
Figure 3-22. HP 5316B Address Switches (20)
3-86. Front Panel HP-IB Status LEDs.
3-87. The two HP-IB Status LEDs on the front panel are to indicate if the counter is in REMOTE and/or
ADDRESSED. The REMOTE light is on when the HP 5316B is in the remote mode. The ADRSD lightis on
when the HP 53168 is addressed to talk or listen. When the HP 5316B goes to local mode, the front panel
REMOTE indicator goes off. The ADRSD indicator stays illuminated if the HP 53168 is still addressed.
When in the TALK ONLY mode the ADRSD LED is always illuminated.
NOTE
The TALK ONLY mode may be entered by the rear panel switch, but
can be exited only by setting the switch to ADDRESSABLE and
pressing the front panel RESET key.
3-88. Device Command D
3-89, A device command is a string or sequence of two or more ASCH-coded bytes (upper or lower
case), ending with a delimiter. (A delimiter is either a comma, semicolon, space, carriage return, or
linefeed.) This command causes the counter to perform a specific function. For the HP 5316B these
commands can be classified as either Terse, Binary, or Numeric commands.

3-90. TERSE COMMANDS: À sequence of two ASCH-coded alphabetic characters NOT
followed by a numeric or binary number.
RE
IN
Reset Causes display to blank and a new measurement to be made. All
functions and parameters remain the same. RESET (RE) also occurs
after the HP 5316B is placed inte Remote. The “RE” command is
equivalent to the bus Device Clear and Trigger commands. The
RESET (REI command may be used to initiate a new measurement.
Initialize Causes the HP 5316B to go to the default state: Function goes to
FREQUENCY A, A and B slopes go to +, and all of the Binary
commands go to the @ state. For example, Initialize (IN) sets the
following codes:
FNTASOBSSTROW ABSREGAS
The HP 5316B will blank the display and make a new measurement
in FREQ A. INOTE: Even if the HP 5316B'was in FREQ A already, “IN”
will still set the Binary commands to 8 and make a new measure-
ment. initialize is commonly sent asthe leading code in a command
string. This will clear all functions ¡to default states) and then only
the codes following in the command string change the operating
mode from the default states..

Channel B triggers on POSITIVE slope of signal.
Channel B triggers on NEGATIVE slope of signal.
The A and B trigger levels are set by front panel controls.
The A and B trigger levels are set by the internal D-to-A Converters. If no numeric
values are specified after a TR1 the DACs go to nominal zero volts DC. (See
Numeric Commands paragraph 3-92b).
Continuous gating mode; output only if addressed to talk.
Gate once, wait for talk address; output data; then make new measurement.
In the Wait state {WA1), the HP 5316B will make a measurement and hold the data
until it has been addressed to talk. At that time, it will output the data and then
make a new measurement. None of the functions or parameters are changed.
Note that WAT allows you to make a measurement and then get the data from
that measurement. Simply addressing it to Talk, in WAG, will send you the results
of the next measurement completed. WAS will continue gating and not hold
the measurement,
HP 53168 WILL NOT pull SRQ at end of measurement.
HP 5316B WILL pull SRQ at end of measurement.
The HP 5316B will request service only to indicate that a measurement is complete
and the data is available. Service Request will occur only if:
1. the “SR1” command has been sent.
2. the WAIT state (WAT) has been enabled.
Reading a device status will return the value 64 (seventh bit active) indicating
that service has been requested. The service request line is cleared when the
НР 53168
HP 53168 is addressed to TALK or when the status is read. Even though SRQ is
cleared during a read device status, the status will remain “64” until the data
is read or a front panel RESET is sent,
Once the data is read {when service has been requested) SRQ will go inactive
and the HP 5316B will start a new measurement. The service request can only
be cleared by reading the measurement data.

b. Programming Trigger Levels:
Commands of the form AT [value] and BT [value] set the D-to-A converters to
DC voltages such that the trigger levels of the A {and B) channels are the value
(in volts) specified. Note that TR1 must also be sent at the beginning of the DAC
programming sequence. (TR1 enables the AT/BT command and need be sent
only once.) The trigger level voltage range is +2.50V dc to -2.50V de, in steps of
3-35
HP 53168
3-36
Ope ration
0.01V dc. The trigger level voltages may be monitored at the front panel
TRIGGER LEVEL jacks. The measurement error at these points is 5% of the
actual voltage +15 mY over the range of +2.0V de. For example all three of
the following formats set the Channel A trigger level to 0V de:
AT 0 (Here the space is ignored)
ATO.00
AT +00
Channel B is exactly the same. To set Channel B to -1.53V:
BT-1.53
Unless specified as negative, the polarity is assumed to be positive.
Sending trigger level commands (AT and/or BT) will cause the HP 53168 to reset.
¢. Programming Gate Time:
GA There are 2 gate time ranges available. The LONG gate time range is 60 ms-
10 s, typical. The SHORT gate time range is 500 us-30 ms, typical. These two
gate time ranges can be controlled by either the front knob or rear panel
adjustment (see Figure 3-11). The rear panel gate time control is essentially the
same as the front panel GATE TIME control WITHOUT the HOLD position.
Commands for the gate time ranges are as follows. Bold indicates the
default states.
GAB Gate time range is LONG, controlled by front knob.
GAT Gate time range is SHORT, controlled by front knob.
GAZ Gate time range is LONG, controlled by rear panel adjustment.
GA3 Gate time range is SHORT, controlled by rear panel adjustment.
NOTE
Placing the GATE TIME/DELAY control in the HOLD position will
cause the bus to stop all operations whenever an attempt is made
to read data from the HP 5316B. When a read data statement is
sent, the HP 5316B cannot send out its data until the GATE
TIME/DELAY control is removed from the HOLD position.
3-93. INPUT CODE FORMAT
3-94. The HP 5316B will accept the program codes in either upper case or lower case. For example:
output 720, INFN7WATSR1” OR output 720, infn7wa1sr1”
Either way will produce the same results. Depending on the controller, this feature can help speed the
writing of programs.
3-95. QUTPUT FORMAT
3-96. After a measurement is complete, the HP 5316B will output the data to the HP-IB. The output
string contains 19 characters, followed by a carriage return and line feed. Table 3-5 shows the output
format of the string. |

PROGRAMMING EXAMPLES
3-99. The examples listed in this section assume a HP 5316B address setting of 10100, The HP 5316B is
addressed to talk and listen by using the code 720, where 20 is the HP 5316B address and 7 is the
interface select code of the 82937A HP-IB for the HP-85.

Special Programming Considerations
To clarify the programming of the HP 5316B, the following considerations should be noted:
If the HP 5316B is currently in REMOTE and new commands are sent, the HP 5316B will reset
and begin a new measurement.
If the HP 5316B is sent back to local from remote and then returned to remote again, all
previous remote functions (slopes, trigger levels, output mode, etc.) will be retained and
reactivated. The gate time, however, is dominated by the locally selected range and
must be programmed again if different.
H a trigger command (group or select) is sent to the HP 5316B while under remote control,
and the HP 53168 is currently making a measurement, a new measurement will begin but
the gate time is shortened. The gate time will be approximately the amount of
time remaining from the interupted measurement. The resolution obtained will be
correct for the shortened gate time,
If a slope command is sent to the HP 5316B and no previous function command was sent,
the HP 5316B will default to Frequency A.
If new commands are sent to the HP 5316B while it is waiting to output data (WAT is active),
the new commands will not become active until the data is read from the counter
(HP 5316B addressed to talk).
The HP 5316B will remember the trigger level values set during remote control when sent to
local. However, if the front panel Reset is pressed while in Local, the trigger level values
stored will default to nominal zero and the Trigger Level/DAC selection will default
to TRE {front panel control).
When writing instructions, the HP 5316B will generally ignore the delimiters in the instruction
string, as long as they occur BETWEEN complete instructions.
To enable Service Request, BOTH WAT and SRT must be sent. WAT can be used alone if
Service Request is not desired.
When operating in FN10, “A gated by B”, the “measurement complete” status is not set.
— SRQ is set at the beginning of the measurement. In order to tell when the measurement is
complete, loop the READ routine and notice when the measurement stops changing.
Or, if the B timing is known, insert a program delay to make sure that the measurement is
complete before the reading is taken.
