4.3.2.3
LAN
The R&S
FSMR3 is equipped with a 1
GBit Ethernet IEEE 802.3u network interface
with Auto-MDI(X) functionality. The assignment of the RJ-45 connector supports twis-
ted-pair category 5 UTP/STP cables in a star configuration (UTP stands for
unshielded
twisted pair
, and STP for
shielded twisted pair
).

Chapter 11, "Network Operation and Remote Control"
4.3.2.4
USB
The rear panel provides four additional female USB (USB-A) connectors to connect
devices like a keyboard, a mouse or a memory stick (see also
Furthermore, a male USB Device connector (USB-B) is provided optionally, for exam-
ple to connect the R&S
FSMR3 to a PC for remote control. The device connector
requires R&S
FSMR3-B114.
All USB connectors support standard 2.0.
4.3.2.5
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. This interface is part of the "Additional Interfaces" hardware option.

4.3.2.6
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
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.
4.3.2.7
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
FSMR3 to receive additional external signals or to pro-
vide signals to another device. The signals are TTL compatible (0
V / 5
V). You control
the connector usage in the "Trigger" settings ([Trigger] key).
