The Keysight/Agilent 53181A Counter provides fast, precise results with the core measurements needed for RF tests. It provides the same signal processing and test automation features as the 53131A and 53132A universal counters, along with 10 digits/second resolution.
The 53181A 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.
