Menu Description
Amplitude
Amplitude can be expressed as Vrms, Vpeak, Vpp, dBV, dBu, and dBm for the analog generator.
Amplitude can be expressed as FFS, dBFS, or %FS for the digital and
Bluetooth generator.
For a perfect sine waveform without any DC offset, Vpp is twice Vpeak and Vrms is equivalent to Vpeak/ √ 2.
DC Offset
This is only available for the analog and Bluetooth generator.
DC Offset refers to the DC component of the waveform.
Start Freq Start Freq refers to the lowest frequency in the multitone waveform which is usually the frequency for the first tone.
Stop Freq Stop Freq refers to the highest frequency in the multitone waveform which is usually the frequency for the last tone.
Freq Spacing
Freq Spacing refers to the frequency spacing between the tones.
– Linear
– Log
– Custom
Tone Count
Tone Count refers to the number of signal frequency components. For analog generator, the maximum number of tones
that can be generated is 60. For digital and Bluetooth generator, the maximum number of tones that can be generated is
64.
Length
Length refers to 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.

Custom
Press the Custom softkey to access the custom multitone menu page. You can set the frequency, amplitude, phase, and
optimize the crest factor for each tone. Refer to “ Custom multitone ” on page 136 for more information on the custom
multitone menu page.
