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 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
Keysight’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 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 transfer 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 measurements up to 3, 5, 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.
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 measurements, choose an
optional second channel that provides measurements up to 1.5, 3, 5, or 12.4 GHz. A self-guided
shallow menu makes this counter exceptionally easy to use.
