14.1.3 Modulation Settings
Modulation is the variation of properties of an original periodic waveform according to a
second modulating signal. The type of modulation determines which properties are
changed.
Modulation
Enables or disables modulation.
Remote command:
WGENerator:MODulation[:ENABLE] on page 445
Modulation Type
Selects the modulation type, which defines how the carrier signal is modified.
"AM"
Amplitude modulation. The amplitude of the carrier signal is varied
according to the modulation signal.
"FM"
Frequency modulation. The frequency of the carrier signal is varied
according to the modulation signal.
"ASK"
Amplitude shift keying (ASK) modulation. The amplitude switches
between 100% and the "ASK Depth" amplitude with a defined modu-
lating "Frequency".
"FSK"
Frequency shift keying (FSK) modulation. The signal frequency
switches between the carrier "Frequency" and the "Hop. Frequency"
at a "FSK Rate".
Remote command:
WGENerator:MODulation:TYPE on page 445
Function
Selects the type of the modulating signal for AM or FM modulation.
Remote command:
WGENerator:MODulation:FUNCtion on page 445
Frequency
Sets the frequency of the modulating waveform for AM/FM/ASK modulation.
Remote command:
WGENerator:MODulation:AM:FREQuency on page 446
WGENerator:MODulation:FM:FREQuency on page 446
WGENerator:MODulation:ASK:FREQuency on page 446
AM Depth
Sets the modulation depth, the percentage of the amplitude range that is used for AM
modulation.
Remote command:
WGENerator:MODulation:AM:DEPTh on page 446
Deviation
Sets the frequency deviation, the maximum difference between the FM modulated sig-
nal and the carrier signal.
