Hp 5315A portable universal frequency counter - as-is
* Exceptional resolution at both low and high frequencies
* Three time-interval modes solve more problems
* 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
* Proven reliability and excellent RFI protection
* 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.
* Flexible Signal Conditioning
* Choose ac or dc coupling, a sensitivity control (variable attenuator), and a switchable low-pass filter. Both channels have trigger level controls with easy setting.
