Timing In The Waveform Comparison / Waveform And Displacement Comparison Mode - Unipulse f395 Operation Manual

13.Waveform Comparison / Waveform and Displacement Comparison Mode
13-6. Timing in the Waveform Comparison /
Waveform and Displacement Comparison Mode
After the indicated value crosses over the Waveform Start Level, and the rising edge of
the START signal is input, when sampling enters the comparison area, waveform
comparison starts, and comparisons are made until the comparison area ends, or
waveform capturing is completed (See "9. Method of Starting Measurement" P43.)
Sampling is performed until inputting of the STOP signal, excess of 2048 points, or
crossing over the Waveform Terminal Level (when the signal "Waveform termination
level operation" is ON).

t1: Delay time between the instant when the indicated value exceeds the waveform start
level and the instant when the hold is detected. Ts msec (max.)
t2: Delay time between the instant when the START signal is input and the instant when
the comparison starts. Ts+0.8msec (max.)
t3: Minimum START signal width Ts+0.8msec (min.)
t4: Standby time to start the next comparison Approx. 300msec
t5: Delay time between the instant when the STOP signal is input and the instant when
the area ends Ts+0.8msec (max.)
t6: Delay time between the instant when the START signal is input and the instant when
the judgment output and COMPLETE change. Ts+1.6msec (max.)
t7: Delay time between the instant when NG occurs and the instant when the judgment
output and COMPLETE change. Ts+1.6msec (max.)
