The Agilent/Keysight Technologies 53131A 225 MHz, 2-Channel Universal Frequency Counter, 10 digits/s, 500 ps, Refurbished high-performance counter gives you fast, precise frequency measurements. It features an intuitive user interface and one-button access to frequently used functions so that you can make accurate measurements quickly and easily. For a unit with an optional timebase for increased stability, please see Model 53131A-010.

Real-time digital signal processing technology is used to analyze data while simultaneously taking new readings, speeding measurement throughput. The technology, developed for high-end 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 counter offers built-in statistics and math functions so that 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 counter also flags 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.

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.

For computer-controlled systems applications, the 53131A 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 IntuiLink: Easy Access to Your Counter's Data from Your PC

The Keysight 53131A counter captures 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. Keysight IntuiLink lets you:

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

Choose display modes from real-time strip chart, histogram, readout, and table mode

Scale measurements data

Copy captured data to other programs
