An acCurale arid jitter-free delay-by-liTIeis very uselul when worklng wilh digtlallogic, pcm lelemetry, sonar, radar, shock tube testing. Ind delay ine measurements,to name a few. On r~t trigger, the 7011 in the delay-by-tiTle mode counts a ~ accurale clock; al the selected delay time, it deJivers a delayed trigger to its front-panel comector arid malnframe In both modes, deIay time or number of events to be counted is selected by a single front-panel contra!
When the 7011 is instalIed in avertical compartmenl, the CRT can display a waveform that lasts tor the duratkJn of the delay inlerval This waveform may be displayed together with the signal waveform the 7011 triggers on From a vertical
