Description
When this softkey is selected, the swept signal generator waits for an
external hardware trigger to trigger a sweep. Connect the trigger
pulse to TRIGGER INPUT. It is activated on a TTL rising edge. An
asterisk next to the key lab el indicates that this feature is active.

Description
This softkey lets you designate the swept signal generator as the
master control in a dual swept signal generator measurement system.
A dual swept signal generator system (two-tone measurement
system) facilitates accurate device characterizations by providing
one timebase reference for b oth sources. This technique reduces
instabilities from temp erature or line voltage uctuations, or drift.
The swept signal generators can be op erated in either ramp
sweep or step sweep modes for b oth xed oset and sw
ept oset
measurements. Figure S-1 shows the connections required for a
two-tone system.
