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.
3.2.2.14
External Generator Control Option (R&S
FSW-B10)
The external generator control option provides an additional GPIB connector and AUX
port.
The GPIB connector can be used to connect the external generator to the R&S
FSW.
The AUX port is required for TTL synchronization, if supported by the generator. It is
identical to the standard AUX port (see
For details on connecting an external generator see the "External Generator Control"
section of the R&S
FSW User Manual.
3.2.2.15
OCXO Option (R&S
FSW-B4)
This option generates a 10 MHz reference signal with a very precise frequency. 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). No warm-up time is required when starting from standby mode.
3.2.2.16
REF INPUT / REF OUTPUT
The REF INPUT connectors are used to provide an external reference signal to the
R&S
FSW.
The REF OUTPUT connectors can be used to provide an external reference signal (or
the optional OCXO reference signal) from the R&S
FSW to other devices that are con-
nected to this instrument.
Various connectors are provided for different reference signals:
