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.
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.
