external hardware trigger to trigger a sweep. Connect the trigger
pulse to TRIGGER INPUT. It is activated on a TTL rising edge. An

This softkey lets you designate the swept CW generator as the
master control in a dual swept CW generator measurement system.
A dual swept CW generator system (two-tone measurement
system) facilitates accurate device characterizations by providing
one timebase reference for both sources. This technique reduces
instabilities from temperature or line voltage fluctuations, or drift.
The swept CW generators can be operated in either ramp
sweep or step sweep modes for both fixed offset and swept offset
measurements. Figure
