When this
is selected, the swept CW 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 label indicates that this feature is active.

This
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
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
S-l
shows the connections required for a
two-tone system.
