6. Repeatedly press MENU until the instrument returns to normal operation.
CAUTION. This function is used mostly for troubleshooting by qualified techni-
cians. It is not recommended that you use the 1502C as a stand-alone monitor-
ing device. The input circuitry is very sensitive and can be easily damaged by
even moderate level signals.
NOTE. In this mode, the 1502C is acting as a detector only. Any pulses detected
will not originate from the instrument, so any distance readings will be invalid.
If you are listening to a local area network, for example, it is possible to detect
traffic, but not possible to measure the distance to its origin.
Pulse is: Off can be used in conjunction with Max Hold is: On.
7. To exit Pulse is: Off, access the Acquisition Control Menu again, turn the
pulse back on, then repeatedly push MENU until the instrument returns to
normal operation.
The single sweep function will acquire one waveform only and display it.

6. Repeatedly press MENU until the instrument returns to normal operation.

also be initiated when you change any of the front-panel controls. This
allows you to observe front panel changes without exiting the Single Sweep
mode.
As in normal operation, averaged waveforms will take longer to acquire.
