SAVE/RECALL
The R3131A allows you to store and recall measured waveform
data and measurement conditions. The R3131A unit offers up
to 10 dedicated files for storage. In addition, the built-in
standard floppy disk drive allows, you to store them on MS-
DOS formatted floppy disks.
MULTIPLE MARKERS
Up to 10 markers can be set. Therefore, this feature is useful
for applications that require the measurement of each level of
multiple carrier signals, filter cutoff characteristics, etc. at
multiple marked points.
PASS/FAIL
There is a choice of two types of limit tests for waves to be
measured. One is a simple method, in which either a signal
level or frequency is evaluated for wave shape in accordance
with a given window range. The other is a limit line method,
in which electromagnetic compatibility (EMC) and filter char-
acteristics are evaluated in accordance with the limit lines.
GATED SWEEP
Bursted signals could not directly be observed with former
spectrum analyzers. The R3131A allows spectrum analysis of
the burst signal by supplying a trigger signal synchronizing
with the burst transmission.

The window range set along the X and Y axes is the PASS area. The
signal level or frequency at a marked point is evaluated in accordance
with the range.
Any UPPER and LOWER limit lines can be set. Pass or Fail judge-
ment can be made in accordance with the limit lines.
