Unipulse f395 - Relative Maximum Value; Relative Minimum Value Hold

10.Multi-Hold Mode
56
10-3-8. Relative Maximum Value / Relative Minimum Value Hold
Detection is performed while the H/M signal is ON from the instant when the indicated
value crosses over the Waveform Start Level. The hold can be cancelled by turning on
the T/H signal as a reset signal.
Example: Relative Maximum Value Hold
t1: Delay time between the instant when the indicated value exceeds the hold start level
and the instant when the hold is detected.
Ts msec (max.)
t2: Delay time between the instant when the H/M signal is input and the instant when it is
detected that the indicated value exceeds the hold start level.
Ts+0.8msec (max.)
t3: Delay time between the instant when the T/H signal is input and the instant when the
indicated value returns to tracking.
Ts+0.8msec (max.)
