Anritsu MF1602A Frequency Counter

The Anritsu MF1602A is a dual-channel frequency counter engineered for high-speed, high-resolution RF measurements across communication and test applications. It delivers 10-digit display resolution in one second using reciprocal and vernier techniques, with a measurement throughput of 80 ms. The instrument performs frequency, period, pulse width, and totalizing measurements with specialized capabilities for burst signals, noisy environments, and delayed-gate analysis.
