Furthermore, a male USB Device connector (USB-B) is provided optionally, for
example to connect the R&S
FSMR3 to a PC for remote control. The device con-
nector requires R&S
FSMR3-B114.
All USB connectors support standard 2.0.
5.2.5
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. This interface is part of the "Additional Interfa-
ces" hardware option.
For more details, refer to "Setting Up Remote Control" in the R&S
FSMR3 user
manual.
5.2.6
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
FSMR3-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.
5.2.7
Trigger 2/3 In/Out
The additional female BNC Trigger 2 In/Out connector and the optional Trigger 3
(output) connector allow the R&S
FSMR3 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).
5.2.8
REF Input / REF Output
The REF Input connectors are used to provide an external reference signal to the
R&S
FSMR3.
