A family of universal and

RF counters to meet your needs

Agilent Technologies 53131A/132A/ 181A high-performance counters give you fast, precise frequency measurements at an affordable 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 readings, speeding measurement throughput. The technology, developed for Agilent’s high-end line of modulation domain analyzers, allows the counters to gather more data for each measurement, 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 deviation. Automated limit testing lets you set upper and lower limits for any measurement. An analog display mode lets you see at a glance whether a measurement 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 frequently used tests, a single keystroke recalls up to 20 different stored frontpanel 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 transfer to a computer through a terminalemulation program.

Agilent 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 measurements up to 3 GHz, 5 GHz, or 12.4 GHz. Standard measurements include frequency, period, ratio, time interval, pulse width, rise/fall time, phase angle, duty cycle, totalize, and peak voltage.

Agilent 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.

Agilent 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 measurements, 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.

Agilent IntuiLink provides easy access to the counter’s data from your PC

The Agilent 53131A/132A/181A counters, capture precise frequency and time measurements. IntuiLink software allows that data to be put to work easily. You work in a familiar environment at all times, using PC applications such as Microsoft Excel® or Word® to analyze, interpret, display, print, and document the data you get from the counter.

It gives you the flexibility to configure and run tests from your PC making data gathering more convenient.

Agilent IntuiLink lets you:

•Configure tests, including measurement type, number of readings, measurement speed, and more.

•Choose display modes from realtime strip chart, histogram, readout, and table mode.

•Scale measurements data.

•Copy captured data to other programs.

Optional timebases offer increased stability

Optional timebases are available for 53131A/132A/181A counters to

increase measurement accuracy. Option 010 provides a high stability oven timebase with aging of less than

5 x 10-10 per day.

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.

Out-of-limits Indications:
• The limits annunciator will light on the front
panel display.
• The instrument will generate an SRQ if
enabled via GPIB.
• The limits hardware signal provided via the
RS-232 connector will go low for the duration
of the out-of-limit condition.
• If the analog display mode is enabled, the
asterisk appears outside the vertical bars,
which define the upper and lower limits.

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:
Time base error =

(

)

∆f
∆f
∆f
— 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 =

(E input ) 2 + (E signal ) 2
Input signal slew rate at trigger point

(in seconds)

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: ±

0.5 x hysteresis band
Input signal slew rate at start trigger point

0.5 x hysteresis band

–

Input signal slew rate at stop trigger point

15 mV ± (1% x start trigger level setting)
Input signal slew rate at start trigger point

15 mV ± (1% x stop trigger level setting)
Input signal slew rate at stop trigger point

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.

The graphs may also be used to compute errors
for period measurements. To find the period
error (DP), calculate the frequency of the input
signal (F = 1/P) and find the frequency error
(DF) from the chart.
Then calculate the period error as:
