Frequency Mask Trigger Configuration
Create or recall a Frequency Mask to be used with the FreqMaskTrigger feature.
NOTE The Mask file is saved to, and recalled from, the Save /Recall Storage Device location
– NOT from the Record Playback Storage Device location. These are two different

A mask that is in use during a recording is NOT saved with the recording and does

When used with Record Interval, a trace is recorded when a limit is exceeded,
then no recordings during the specified 'wait' interval, then the next trace is
recorded, followed by another time delay, and so forth. This pattern repeats
indefinitely if Segment Count is OFF, or (if ON) until Segment Count is reached.
