Description This softkey lets you designate the synthesizer as the master control in a dual synthesizer measurement system. A dual synthesizer 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 synthesizers 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.
