OPERATION
3-l. INTRODUCTION
3-2.
This section provides complete operating information needed for the HP 5314A Universal
Counter. This section includes a description of all front panel controls, connectors and indi-
cators, operating instructions,_operator’s checks, and operator’s maintenance.
3-3. OPERATING CHARACTERISTICS
3-4. The following paragraphs describe the operating ranges and resolution for frequency,
period, time interval, ratio A/B, totalize A, and self-check functions.
3-5.
Frequency Measurements
3-6. All frequency measurements are made through the A channel input. The frequency range
is 10 Hz to 10 MHz direct count and IO Hz to 100 MHz prescaled by 10, with a minimum input
level of 25 mV rms or 75 mV p-p (with a minimum pulse width of 5 ns) times the attenuator setting.
The resolution is 0.1 Hz for frequencies up to IO MHz. With frequencies above 10MHz (prescale
mode), the resolution is 10 Hz. See Figure 3-3 for a typical frequency measurement setup.
3-7. Period Measurements
3-8.
All period measurements are made through the A channel input. The signal can be a sine
wave, square wave, or a wave form with components faster than IO Hz. The period range is 100 ms
to 400 ns (10 Hz to 2.5 MHz). The sensitivity is 25
mV rms or 75 mV p-p. The resolution is 100 ns. See
Figure 3-4 for a typical period measurement setup.
3-9. Time Interval Measurements
3-10.
The counter measures time intervals from Channel A to Channel B; that is, Channel A
starts the measurement and Channel B stops the measurement. Time between points on a single
waveform can be measured by connecting the input signal to CHANNEL A jack and placing the
Input Amplifier Control switch to COM A. Under these conditions, the slope and level controls
of Channel A and Channel B allow variable triggering on either the + or
- slope. With the Input
Amplifier Control switch set to SEP, measurements can be made between points on separate
waveforms. The time interval range is 250 ns to 1 s. The sensitivity is 25 mV rms (75 mV p-p). The
resolution is 100 ns. See Figures 3-5 and 3-6 for typical time interval measurement setups.
3-11. INITIATING A MEASUREMENT. The HP 5314A does not internally arm itself in time
interval. Both Channels A and B must be externally armed before a time interval measurement
can be initiated, see Figure 3-1. Each channel is armed by the first positive or negative edge
(corresponding to the slope selection setting) of the input signal. Channel A is armed first.
Channel B ignores all input edges until Channel Ais armed. Once Channel Ais armed, the first
positive or negative edge (corresponding to the slope selection setting) arms Channel B. Until
Channel B is armed, Channel A ignores any further input edges. Once Channel B is armed, the
next
slope selected edge in Channel A starts the time interval measurement, and the next slope
selected edge in Channel B stops the time interval measurement.

3-20. OPERATING INSTRUCTIONS
3-21. General operating procedures with the HP Model 5314A Universal Counter connected in
typical measurement setups are shown in Figures 3-3, 3-4, 3-5, 3-6, 3-7, and 3-8. Many other
applications are possible but not shown because the general operating procedure is the same.
Description numbers match the numbers on the illustration.
3-22. OPERATOR’S MAINTENANCE
3-23. There is no operator’s maintenance for the HP 5314A. All maintenance should be per-
formed by qualified service personnel only.
3-24. Power/Warm-Up
3-25. The HP 5314A has a two position power switch, STBY and ON. For HP 5314A models with
Option 002, it is important that the instrument be connected to the power source in the STBY
mode when not in use. This supplies power to the battery charging circuitry.

stopped, the main counter is reset, and the
HP 5314A is held ready to make
a new measurement. The latches are not updated so the last complete
measurement is displayed.
When switched back to NORM, a new mea-
surement is initiated. In totalize, when placed in HOLD, the display is held
but the counters continue to increment. When the HOLD is released, the
display is updated and resumes counting.
With this switch IN,
the HP 5314A is placed in either frequency or totalize

There are two additional functions which are selected using
combinations of switches @and@. These two functions
are Self-Check and Ratio A to B. For self-check mode, place
both function switches
@ and @in the IN position. The
instrument is now making a frequency measurement on the
internal 10 MHz time base. Activating switches
causes 10 MHz to be displayed. Activating
causes 100 MHz to be displayed. Resolution selection

are dual purpose.
Depending on the function selected (Frequency, Period,
Ratio, etc.) the switches either represent the resolution and
bandwidth (gate time) or the sample size (N samples).
In frequency
(10 Hz to 10 MHz), this switch, when IN, gives a display with a
1 Hz resolution (1 second gate time). For frequencies between 10 MHz and
100 MHz, see the explanation for switch@. In period, this switch, when
IN, causes the HP 5314A to measure 100 periods and display the average
value
in microseconds. In ratio, this switch when IN, causes the HP 5314A to
make 100 measurements and display the average ratio. This switch does not
improve accuracy
beyond 100 nanoseconds for time interval
measurements!
0
I 10 Hz/N=10
In frequency (10 Hz to 10 MHz), this switch, when IN, gives a display with a
10 Hz resolution (100 millisecond gate time). For frequencies between
10 MHz and 100 MHz, see the explanation
for switch@ . In period, this
switch, when IN, causes the HP 5314A to measure 10 periods and display
the average value
in microseconds.
In ratio, this switch, when IN, causes the HP 5314A to make 10 measure-
ments and display the average ratio. This switch does
not improve accuracy
beyond 100 nanoseconds
for time interval measurements!
NOTE
There is another resolution available using switcheseand
0
I in addition to the two resolutions called out on the
front panel. It is 0.1 Hz N=1000 This is generated when
switches
q@and -6
are in the OUT position. In fre-
quency (10 z to 10 MHz), with these three switches out,
the
HP 5314A gives a display with 0.1 Hz resolution (10
second gate time). For frequencies between IO MHz and
100 MHz, see the explanation for switch @. In period,
with these three switches out, the HP 5314A measures 1000
periods and displays the average value in microseconds. In
ratio, with these three switches out, the HP 5314A makes
1000 measurements and displays the average ratio. This
switch combination does
not improve accuracy beyond
100
nanoseconds for time interval measurements.
