4.1 Setting Criteria to Start and Stop Recording
70
An input signal level “window” within which recording
will (or will not) occur can be defined by upper and
lower threshold levels. You can select whether record-
ing starts or stops when the input signal level enters
(In) or exits (Out) of this window.
Upper and lower thresholds can be verified in the level
monitor or on the Waveform screen. When scaling is
enabled, the scaled threshold values are displayed.
