GPIB Interface

The GPIB interface is in compliance with IEEE488 and SCPI. A computer for
remote control can be connected via this interface. To set up the connection, a
shielded cable is recommended. For more details refer to "Setting Up Remote
Control" in the User Manual.

5.2.10 External Generator Control (Optional)

The optional "External Generator Control" provides an additional GPIB interface
and AUX port.
The GPIB connector can be used to connect an external generator to the
R&S ESW.
The AUX port is required for TTL synchronization, if supported by the generator
(see Chapter 5.2.8, "AUX
For details on connecting an external generator see the "External Generator Con-
trol" section of the R&S ESW User Manual.
5.2.11

OCXO (Optional)

This optional OCXO generates a 10 MHz reference signal with a very precise fre-
quency. If installed, and if no external signal is used, this signal is used as an
internal reference. It can also be used to synchronize other connected devices via
the REF OUTPUT 10 MHz connector.
Warm-up time for OCXO
When the instrument is switched on, the OCXO requires an extended
warm-up time (see data sheet).

5.2.12 REF INPUT / REF OUTPUT

The REF INPUT connectors are used to provide an external reference signal to
the R&S ESW.
