PROBE
The R&S
FSW provides a connector for supply voltages of +15 V to -12 V and ground
for active probes and preamplifiers. A maximum current of 140 mA is available. This
connector is suitable as power supply for high-impedance probes.
3.2.1.8
NOISE SOURCE CONTROL
The noise source control female connector is used to provide the supply voltage for an
external noise source, e.g., to measure the noise figure and gain of amplifiers and fre-
quency converting devices.
Conventional noise sources require a voltage of +28 V in order to be switched on and
0 V to be switched off. The output supports a maximum load of 100 mA.
