Format options are not available for AM Noise measurement.
When the downconverter is turned on, the RF input is set to Downconverter, and the external mixer is set to Not Used, the function to search for the carrier signal in the specified carrier frequency band and reflect the result to the nominal frequency is available.
Press Setup.
Press Carrier Search to execute the carrier signal search.
The detected signal frequency is reflected on the nominal frequency.
Press Marker to display marker 1 on the screen.
Move marker 1 to the point you want to confirm and read the measurement value displayed in the upper part of the graph. To confirm multiple values, press Marker > Marker x (x=1 to 10), which allows you to display up to marker 10.
Example of Measurement Screen (AM noise - offset frequency characteristics)
In this measurement, you cannot specify the sweep time. It will be determined automatically based on the selection of the offset frequency sweep range and the carrier frequency band.
