4.2.7
Aux. Port
A 9-pole SUB-D male connector used to provide low-voltage TTL
control signals (max. 5
V). The output signals can be used to con-
trol external devices.
4.2.8
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 R&S
FSPN user
manual.
4.2.9
OCXO
The OCXO generates a 10
MHz reference signal with a very precise frequency. 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).
4.2.10
REF INPUT / REF OUTPUT
The REF INPUT connectors are used to provide an external reference signal to
the R&S
FSPN.
Various connectors are provided for different reference signals:
