Interference Analyzer (SA Mode) – Option 236
Record/Playback (SA Option)
When set, a counter appears in the lower-left corner which counts UP to
the specified number of recordings.
— FreqMaskTrigger OFF ON
Sets the power level which will trigger a recording. Set these power levels
(mask) exactly as you would set Limit Lines. (See “All about Limit Lines” on
page 499.) With Record ON, when 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 (SA Mode Only)
Create or recall a Frequency Mask to be used with the FreqMaskTrigger
feature.
A mask that is in use during a recording is NOT saved with the recording and
does NOT automatically appear during playback. Like Limits Lines, it is saved
and recalled with a state file.
Frequency Mask Trigger only applies to SA mode.
— 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 settings. Learn how to set the Save
/Recall Storage Device in “Set File Type and Select Device” on
page 549.
