Keysight-Agilent 5316B

* 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
* Full frequency range (to 100 MHz) on both input channels
* 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 Modes
