Agilent / HP / Keysight 53131A
53131A 225 MHz Universal Frequency Counter/Timer
The Agilent 53131A high-performance counter gives fast, precise frequency measurements at an affordable price.
The Agilent 53131A counters feature an intuitive user interface and one-button access to frequently used functions so you can make accurate measurements quickly and easily.
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 counter offers built-in statistics and math functions so you can scale measurements and simultaneously measure and track average, min/max and standard deviation.
An analog display mode of the Agilent 53131A lets seeing at a glance whether a measurement is within pass/fail limits.
The 53131A 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 with 53131A counter provides printer support or data transfer to a computer through a terminal-emulation program.
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.
The Agilent 53131A counter captures precise frequency and time measurements. IntuiLink software allows that data to be put to work easily.
