Table 7-34 Multitone Analyzer > Signal Generation settings menu description
Menu Description
Output Press the Output softkey to select the output channel.
Waveform Config
Press the Waveform Config softkey to set the waveform configuration.
– Track 1st Ch
If Track 1st Ch is enabled, the generator channel 1 waveform configuration settings will be copied to the other channels
and the waveform configuration settings for the other channels cannot be edited. Any changes made to channel 1
waveform configuration settings will be reproduced in the other channels waveform configuration settings. Disable the
Track 1st Ch to set the individual channels.
– Amplitude
Set the amplitude value.
Tones Config
Press the Tones Config softkey to set the tones.
– Start freq
The lowest frequency in the multitone waveform.
– Stop freq
The highest frequency in the multitone waveform.
– Freq Spacing
The frequency spacing between the tones.
– Tone Count
The number of signal frequency components. The maximum number of tones that can be generated is 60 for analog and
64 for digital/ Bluetooth .
– Length
The waveform length that determines the number of samples used to create one iteration of the multitone waveform.
Longer waveform length provides higher frequency resolution but will take more time to generate and process.
– Apply
Apply the multitone after it has been customized.
– Optimize
Optimize the multitone.
– Amplitude Dist: Zero
Set the amplitude of all tones to 0 dB.
– Phase Dist: Zero
Set thephase of all tones to 0 degrees.
– Phase Dist: Random
Set thephase of all tones to random phase in degrees.
– Edit Tones
Edit the individual tones frequency, amplitude, and phase.
– Active Channel
The active channel for the absolute amplitude for each tone to be displayed in a table.
