A family of universal and RF
counters to meet your needs
The Keysight Technologies, Inc.
53131A/132A/181A high-performance
counters give you fast, precise fre-
quency measurements at an afford-
able price. These counters feature an
intuitive user interface
and one-button
access to frequently
used functions so
you can make accurate measurements
quickly and easily.
Real-time digital signal processing
technology is used to analyze data
while simultaneously taking new read-
ings, speeding measurement through-
put. The technology, developed for
Keysight’s high-end line of modulation
domain analyzers, allows the counters
to gather more data for each measure-
ment, so you get higher-resolution
measurements in a fraction of the time
it takes other counters.
The 53131A/132A/181A counters offer
built-in statistics and math functions
so you can scale measurements and
simultaneously measure and track
average, min/max and standard devia-
tion. Automated limit testing lets you
set upper and lower limits for any mea-
surement. An analog display mode lets
you see at a glance whether a mea-
surement is within pass/fail limits. The
counters flag out-of-limit conditions
and can generate an output signal to
trigger external devices when a limit
is exceeded. For quick access to fre-
quently used tests, a single keystroke
recalls up to 20 different stored front-
panel set-ups.
For computer-controlled systems
applications, each counter includes
a standard GPIB interface with full
SCPI-compatible programmability and
a data transfer rate of up to 200 fully
formatted measurements per second.
The standard RS-232 talk-only interface
provides printer support or data trans-
fer to a computer through a terminal-
emulation program.
Keysight 53131A universal
counter
The two-channel 53131A counter offers
10 digits per second of frequency/
period resolution and a bandwidth of
225 MHz. Time interval resolution is
specified at 500 ps. An optional third
channel provides frequency measure-
ments up to 3 GHz, 5 GHz, or 12.4 GHz.
Standard measurements include fre-
quency, period, ratio, time interval,
pulse width, rise/fall time, phase
angle, duty cycle, totalize, and peak
voltage.
Keysight 53132A universal
counter
For applications requiring higher
resolution, the 53132A offers the same
features and functions as the 53131A,
with up to 12 digits/sec frequency/
period resolution and 150 ps time
interval resolution. In addition, the
53132A offers advanced arming modes
for time interval measurements.
Keysight 53181A RF counter
Optimized for RF applications, the
single-channel 10 digit/s 53181A
measures frequency, period and peak
voltage. A digit-blanking function lets
you easily eliminate unnecessary digits
when you want to read measurements
quickly. For higher-frequency measure-
ments, choose an optional second
channel that provides measurements
up to 1.5 GHz, 3 GHz, 5 GHz, or 12.4 GHz.
A self-guided shallow menu makes this
counter exceptionally easy to use.

Measurement Specications

Auto arming: Measurements are initiated
immediately and acquired as fast as possible,
using a minimum number of signal edges.
Timed arming: The duration of the measurement
is internally timed to a user-specified value
(also known as the “gate time”).
Digits arming: Measurements are performed
to the requested resolution (number of digits)
through automatic selection of the acquisition
time.
External arming: An edge on the external arm
Input enables the start of each measurement.
Auto arming, timed arming modes or another
edge on the external arm input may be used to
complete the measurement.
Time interval delayed arming: For time interval
measurements, the stop trigger condition is
inhibited for a user-specified time following the
start trigger. The 53132A offers advanced time
interval arming capabilities including use of user
specified time or Channel 2 events to delay both
start and stop triggers.
Measurement limits
Limit checking: The measurement value is
checked against user-specified limits at the
end of each measurement.
Display modes: The measurement result may
be displayed as either the traditional numeric
value or graphically as an asterisk moving
between two vertical bars.

Fractional time base error (see graph 3)
Time base error is the maximum fractional frequency variation of the time base due to aging or
fluctuations in ambient temperature or line voltage:
∆f ∆f ∆f
Time base error
= ( —
Aging rate
+ —
Temperature
+ —
Line voltage
)
f f f
Multiply this quantity by the measurement result to yield the absolute error for that measurement.
Averaging measurements will not reduce (fractional) time base error. The counters exhibit negligible
sensitivity to line voltage; consequently the line voltage term may be ignored.
Trigger error
External source and input amplifier noise may advance or delay the trigger points that define the
beginning and end of a measurement. The resulting timing uncertainty is a function of the slew rate
of the signal and the amplitude of spurious noise spikes (relative to the input hysteresis band).
The (rms) trigger error associated with a single trigger point is:
Trigger error
=
Input signal slew rate at trigger point
(in seconds)
+
(E )
input
2(E )
signal
2
where
Einput = RMS noise of the input amplifier: 1 mVrms (350 µVrms typical). Note that the internal
measurement algorithms significantly reduce the contribution of this term.
Esignal = RMS noise of the input signal over a 225 MHz bandwidth (100 kHz bandwidth when the
low-pass filter is enabled). Note that the filter may substantially degrade the signal’s slew rate at
the input of the trigger comparator.
For two-trigger-point measurements (e.g. rise time, pulse width), the trigger errors will be referred
to independently as start trigger error and stop trigger error.
Trigger level timing error (see graph 6)
Trigger level timing error results from a deviation of the actual trigger level from the specified level.
The magnitude of this error depends on resolution and accuracy of the trigger level circuit, input
amplifier fidelity, input signal slew rate, and width of the input hysteresis band.
The following equations should be summed together to obtain the overall trigger level timing error.
At the “High” sensitivity input setting, the hysteresis band can be assumed to be the sensitivity of
the counter input (see page 2). Reduction of input sensitivity or use of the attenuator will increase the size of this band.
Input hysteresis error: –
Trigger level setting error: ± ±
Differential channel error
The differential channel error term stated in several systematic uncertainty equations accounts for
channel-to-channel mismatch and internal noise. This error can be substantially reduced by performing
a TI calibration (accessible via the utility menu) in the temperature environment in which future
measurements will be made.

trigger error. To place an upper bound on the added
effect of this error term, determine the frequency
error from the appropriate graph and add a trigger

Available statistics
Mean, Minimum, Maximum, Standard Deviation
Number of measurements 2 to 1,000,000.
Statistics may be collected on all measurements
or on only those which are between the limit
bands. When the limits function is used in
conjunction with statistics, N (number of
measurements) refers to the number of in-limit
measurements. In general, measurement
resolution will improve in proportion to N,
up to the numerical processing limits of
the instrument.
Measurements
Statistics may be collected for all measurements
except peak volts and totalize.
Save and recall
Up to 20 complete instrument setups may
be saved and recalled later. These setups
are retained when power is removed from
the counter.
