— Record Interval
recordings. Default is MIN, which is to wait 0 seconds (record traces as fast
as possible). Enter a value in seconds between 0 (no delay) and 10,000
seconds - about 3 hrs) using the numeric keypad,
knob.
— Segment Count
recording will automatically pause. Press Pause/Resume or Record to
capture another N traces, or Stop to end recording. Default is OFF, which is
NO limit to the number of traces to be recorded.
When set, a counter appears in the lower-left corner which counts UP to
the specified number of recordings.
— FreqMaskTrigger OFF ON
recording. Set these power levels (mask) exactly as you would set Limit
Lines. (See
any data point measurement is higher than an upper limit, or lower than a
lower limit, recording begins. See Frequency Mask Trigger Configuration in
the following section to learn how to configure the mask.
Typically you would use FreqMaskTrigger with Segment Count, but it can also
be used with Record Time and Record Interval.
When used with Segment Count:
— When a mask limit is exceeded, subsequent traces are recorded until the
specified segment count is reached. Once segment count is reached,
exceeding another mask limit will again cause traces to be recorded until
the segment count is reached, and so forth.
— To record only those traces that exceed the limit, set Segment Count to 1
— To record ALL traces after a limit is exceeded, set Segment Count OFF.
When used with Record Time, the timer counts down even when traces are not
being recorded (limits are not being exceeded). Recording starts when a limit is
exceeded and stops when the timer reaches 0.
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.
Frequency Mask Trigger Configuration
Create or recall a Frequency Mask to be used with the FreqMaskTrigger
feature.
The Mask file is saved to, and recalled from, the Save /Recall Storage
Device location – NOT from the Record Playback Storage Device location.
