Recording Configuration
Then choose from the following:
— Record Time Sets the amount of time to record traces. Default is MAX,
which is to record indefinitely. Enter a value between 1s and 1 Ms (million)
seconds using the numeric keypad, arrows, or the rotary knob. When
set, a timer appears during recording in the lower-left corner which counts
DOWN from the specified time.
— Record Source Sets where, in the FieldFox data flow, data is recorded.

“Record Source” on page 552. Choose from the following:
— RawMeas
Records raw measurement data.
—
Trace 1,2,3,4 Records data from the corresponding trace in its
current state.
— Record Interval
Sets the amount of time to wait between individual trace
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, arrows, or the rotary
knob.
—
Segment Count Sets the number of traces to record, after which the
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
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 749
.) 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.
