Use the
function to determine the required measurement parameters automat-

The following settings are determined:
●
Peak markers
●
Center frequency of 2 narrowband signals creating intermodulation products

The marker positions can be edited; the TOI is then recalculated according to the new
marker values.
To reset all marker positions automatically, use the

How to Determine the Third Order Intercept
The precise TOI for the R&S
FSV/A in relation to the input signals is provided in the
data sheet.
For remote operation, see
Chapter 14.5.11.2, "Programming Example: Measuring the
1. Apply a two-tone signal with equal carrier levels to the R&S
FSV/A input.
2. On the R&S
FSV/A, press the [MEAS] key.
3. Select the "Third Order Intercept" measurement function from the "Select Measure-
ment" dialog box.
