occurs.
The sweep steps within the cycle are performed automatically, con-
trolled by the dwell time. If one cycle is completed, the instrument
waits for the next trigger event.

Refer to the description of the rear panel for information on the con-
nectors for external trigger signal input (see
Chapter 2.2, "Rear Panel
Tour" , on page 27).

SOUR:LFO:FREQ:MODE SWE
(External trigger)
