The results are displayed the same way as in the other measurements (two
traces in the diagram and results for the integrated measurements).
If no frequency or pulse could be found, a corresponding error message is dis-
played in the status bar below the diagram.
If required, you can also define the
manually.

The Pulsed Additive Noise Measurement
Additive noise measurements on pulses require the optional pulsed phase noise
measurements firmware application and the optional signal source output.
The test setup depends on whether you use internal or external modulation with a
pulse modulator.

How to measure pulsed additive noise with an internally modulated pulse
1. Connect the signal source (supplies the pulse) to the DUT.
The pulse is modulated internally and output on the signal source.
2. Connect the DUT to the RF input.
3. Perform a [PRESET].
4. Select the [MEAS] key and select the "Pulsed Additive Noise" measurement.
5. Enter the "Overview" dialog box, and from there, enter the "Output" dialog
box.
6. Select the "Signal Source" tab and turn on the "Pulse Modulator".
7. Configure the
.
8. Start the measurement with [RUN SGL] or [RUN CONT].
