HP 5315A UNIVERSAL COUNTER 100 MHz

• Flexible signal conditioning optimized for both frequency and time interval measurements

• Selectable gate time from 60 ms to 10 s

• 100 MHz A and B input channels, Optional 1 GHz C channel

• Below 10 MHz, the counter measures the input signal period, then computes and displays the reciprocal frequency with 7 digits of resolution in one second for signals as low as 0.1 Hz. Above 10 MHz, the counter automatically performs as a conventional counter. Three Time-Interval Modes

• The 5315A offers 100 ns single-shot time-interval resolution. Time-interval averaging boosts performance to 10 ps resolution. A time-interval delay ignores spurious signals that would normally cause the counter to trigger.
