SAVE/RECALL

The R3131 allows you to store and recall measured waveform

data and measurement conditions. The R3131 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.

PASS/FAIL

Sets the limited judgment value for the level axis using a

window. If the marker falls within the window, the PASS

judgment results; otherwise, the FAIL judgment results. Since

the limit value is set as an absolute value, you can make

measurement with the same judgment value with different

REF levels. In addition, by setting the limit window for the

frequency axis, the portion where the X and Y axes overlap is

judged as the PASS region.

GATED SWEEP

Bursted signals could not directly be observed with former

spectrum analyzers. The R3131 allows spectrum analysis of the

burst signal by supplying a trigger signal synchronizing with

the burst transmission.
