Multitone Analyzer - Keysight U8903B User Manual

Multitone analyzer

Multitone analyzer measurement uses the FFT analysis with a multitone stimulus
waveform. The multitone stimulus signal is the combination of two or more sine waveforms.
The multitone signal is applied to the DUT, and the DUT output is acquired for
measurement. You can create a multitone from the Tones Config menu page in the signal
generation settings.
The result for the multitone analyzer measurement for all the selected channels are
displayed in a graph (Spectrum, Waveform, Level, and Gain) and in a bar chart (Max Tone
Level, Min Tone Level, TD+N Level, TD+N Ratio, and Tone Level). Refer to "Measurement
Results" on page
arrow keys to navigate through the respective tabs and to display the menu page.
This measurement requires a closed-loop configuration in which both the generator and
NOTE
the analyzer are used in the test setup. If None is selected for the output configuration
channel, this measurement is unavailable. This measurement is also unavailable if a
different interface is selected for the output and input configuration channel.
Signal generation
The signal generation is disabled if None is selected for the output configuration channel.
NOTE
The multitone analyzer signal generation settings menu page is displayed as shown in
