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
FSMR3 is directly coupled
with the frequency stepping of the generator. For details see
In
the TTL connection is illustrated using an R&S SMU generator, for exam-
ple.
