3.3.2.4 USB
The rear panel provides 2 additional female USB (USB-A) connectors to connect devi-
ces like a keyboard, a mouse or a memory stick (see also
Chapter 3.3.1.2, "USB" ,
on page 59).
The USB connectors support USB standard 3.0.
3.3.2.5 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 Chapter 11, "Network operation and remote control" ,
on page 773.
3.3.2.6 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. This connector requires option
R&S
FSV3-B28V.
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.
For smart noise sources, use the Lemosa Noise source control / power sensor connec-
tor.
For details on noise source control, see "Noise Source Control" on page 440.
3.3.2.7 Trigger 2/3 in/out
The additional female BNC Trigger 2 In/Out connector and the optional Trigger 3 (out-
put) connector allow the R&S
FSV/A to receive additional external signals or to provide
signals to another device. The signals are TTL compatible (0 V / 5 V). You control the
connector usage in the "Trigger" settings ([Trigger] key).
3.3.2.8 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:
