HP 53131A Universal Counter

Agilent 53131A/132A/181A
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.

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, an optional second channel can provide 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.
