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 FSW is directly coupled with
the frequency stepping of the generator. For details see "Coupling the Frequencies"
on page 389.
In Figure 8-4 the TTL connection is illustrated using an R&S SMU generator, for exam-
ple.

The external generator can be used to calibrate the data source by performing either
transmission or reflection measurements.
Transmission Measurement
This measurement yields the transmission characteristics of a two-port network. The
external generator is used as a signal source. It is connected to the input connector of
the DUT. The input of the R&S FSW is fed from the output of the DUT. A calibration
