Low-temperature socket, fuse holder and line voltage selector
After selection of the voltage range, connect the V-network to the supply voltage using
the supplied power cable. If the V-network is correctly connected, one of the four green
LEDs for displaying the test path should light up (depending on the position of the LINE
SELECTION rotary switch).
If the V-network is connected to 230 V and the voltage selector is set to 115 V, the V-
network's internal F3/F4 fuses may blow. The internal F3/F4 fuses may be replaced
only by an authorized Rohde & Schwarz service center (two spare fuses are part of the
equipment supplied).
4.7 Connecting the Test Receiver
Connect the test receiver using a 50
coaxial cable to the test receiver output (50
N
female connector TO TEST RECEIVER).
The external conductor of the N female connector is connected to the grounding bars
of the V-network via the front panel.
