External noise sources are useful when you are measuring power levels that fall below
the noise floor of the R&S
FSV/A itself, for example when measuring the noise level of
an amplifier.
In this case, you can first connect an external noise source (whose noise power level is
known in advance) to the R&S
FSV/A and measure the total noise power. From this
value, you can determine the noise power of the R&S FSV/A. Then when you measure
the power level of the actual DUT, you can deduct the known noise level from the total
power to obtain the power level of the DUT.

6.2.8 IF/Video output
Access : [Input/Output] > "Output" > "IF/Video" tab
Defines the type of signal available at the "IF" and "Video" output connectors of the
R&S
FSV/A.
For restrictions and additional information, see Chapter 6.2.1.3, "IF and video signal
output" , on page 356.

IF Out Frequency
Defines or indicates the frequency at which the IF signal level is provided at the "IF"
output connector if
IF Output State is enabled.
