A7021 – COUNTER FREQUENCY – AN/USM-495A

The 1992 Universal Counter provides Frequency, Period, Time Interval, Ratio, Totalize, Phase, and Peak Amplitude measurements. It covers the frequency range of DC to 1.3GHz. Channel A’s sensitivity is 25 mV rms to 100MHz and 50 mV rms to 160MHz. Channel B: Same sensitivity as Channel A except that the frequency range is 10Hz to 100MHz. Channel C’s sensitivity isless than 15 mV rms from 40MHz to 1GHz and less than 75 mV up through 1.3GHz.
