R&S ESR
The difference between the two GPIB operating modes is the execution speed. While,
during GPIB operation, each frequency to be set is transmitted to the generator sepa-
rately, a whole frequency list can be programmed in one go if the TTL interface is also
used. Frequency switching can then be performed per TTL handshake which results in
considerable speed advantages.
Notes: Only one of the two generators can be operated via the TTL interface at a time.
The other generator must be configured via GPIB.
For Noise Figure measurements (K30), TTL synchronization has no effect.
This command is only available if the R&S FSV-B10 option (External Tracking Genera-
tor) is installed.

This command selects the type of external generator. For a list of the available genera-
tor types including the associated interface, see
tors Supported by the R&S
If no external generator type is currently configured, the query returns "NONE".
This command is only available if the R&S FSV-B10 option (External Tracking Genera-
