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. This interface is part of the "Additional Interfaces" hardware option.

REF Input / REF Output
The REF Input connectors are used to provide an external reference signal to the
R&S
FSV/A.
The REF Output connectors can be used to provide an external reference signal (or
the optional OCXO reference signal) from the R&S
FSV/A to other devices that are
connected to this instrument.
Various connectors are provided for different reference signals:
Connector
Reference signal
Usage
REF Output 2
640 MHz
10 dBm
To provide the internal reference signal from the R&S
FSV/A
to another device continuously.
Also used to provide OCXO reference signal to another
device.
REF Input 2
10 MHz - 1280 MHz
3 dBm - 13 dBm
To provide an external reference signal to the R&S
FSV/A.
REF Output 1
1 MHz - 100 MHz
> 0 dBm
To provide a 640 MHz reference signal from the R&S
FSV/A
to another device.
REF Input 1
1 MHz - 100 MHz
0 dBm - 15 dBm
To provide an external reference signal to the R&S
FSV/A.
5.2.2.12
Noise Source Control
The Noise Source Control female connector is used to provide the supply voltage for
an external noise source. For example, use it to measure the noise figure and gain of
amplifiers and frequency converting devices.
Conventional noise sources require a voltage of +28
V to be switched on and 0
V to be
switched off. The output supports a maximum load of 100
mA.
5.2.2.13
OCXO Option (R&S
FSV3-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 640
MHz connector.
