Interference Analyzer (SA Mode) – Option 236

Record/Playback (SA Option)

— 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

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

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.

Although they are created in the same manner, Limit Line files and FreqMask

files can NOT be used interchangeably.
