External Generator Connections
The external generator is controlled either via a LAN connection or via the EXT. GEN.
CONTROL GPIB interface of the R&S FSV/A supplied with the option.
For more information on configuring interfaces see Chapter 13.1.1, "Remote Control
Interfaces and Protocols", on page 644.
TTL synchronization
In addition, TTL synchronization can be used with some Rohde & Schwarz generators
connected via GPIB. The TTL interface is included in the AUX control connector of the
External Generator Control option.
Using the TTL interface allows for considerably higher measurement rates than pure
GPIB control, because the frequency stepping of the R&S FSV/A is directly coupled
with the frequency stepping of the generator. For details see "Coupling the Frequen-
cies" on page 332.
In Figure 8-3, the connection for an R&S SMW is shown.
