Advantest TR5823 Universal counter

The Advantest TR5823 Universal Counter delivers precision frequency, period, and time interval measurements across a 1 mHz to 1300 MHz range. This instrument employs three independent measurement methods—reciprocal, direct, and prescale—to maintain accuracy from sub-hertz to microwave frequencies. Designed for R&D, production test, and signal analysis environments, it combines fast measurement throughput with exceptional time base stability and optional GPIB/BCD interfaces for automated system integration.
