Model 1120 - 1pS Time Interval Counter 1. NUT 012 Ed. 6 Date : 18/01/2011 GENERAL INFORMATION The BNC 1120 1pS Time Interval Counter measures time interval, frequency and events. The single-shot resolution and low jitter of the instrument make it the ideal for many test and measure application. Time intervals are measured with 1 ps resolution. Frequency and events are measured up to 10 MHz Trigger level and slope are adjustable on each input.
