Output mode is determined by a front-panel locking toggle switch. Their long-term stability is excellent, permitting their direct use in critical coincidence applications without any need for external clipping cables. In the Burst Guard mode the output duration is either equal to the time-overthreshold of the input signal or is equal to the preset output duration, whichever is greater. Input burst rates that exceed the DPR of the unit will cause an output for the duration of the burst. C over 20Deg.
Output falltimes slightly longer on wide output durations.
Other characteristics same as for Fast Negative Timing Output. Output duration is either equal to the time-overthreshold of the input signal or equal to the preset duration. For input burst rates greater than the DPR of the unit, the output is equal to the duration of the burst. Less than 9 ns at minimum output width setting. 9.5 ns typical.
