5315A - Keysight / Agilent Frequency Counters

Keysight / Agilent 5315A Overview

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 Exceptional Resolution 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
