Modulation
8.5.1

Select ASK modulation

Press [Mod] >

When Mod
⚫
After ASK is enabled, the instrument will generate ASK waveform with the currently
specified carrier and modulating waveforms. To avoid multiple waveform changes,
enable modulation after configuring the other modulation parameters.
8.5.2

Carrier Waveform Shape

ASK carrier shape: Sine (default), Square, Ramp, Pulse, Arbitrary (except DC) or
Harmonic waveform.
⚫
Press [Wave] button on the front panel to select the desired carrier waveform.
⚫
Noise and DC could not be used as carrier waveform.
8.5.3

Carrier Waveform Amplitude

After selecting the carrier waveform, press [Setting] >
panel, use the numeric keypad or direction keys and knob to input the desired amplitude.
The amplitude range is limited by frequency. Please refer to the "Output Characteristics"
described in Specifications.
8.5.4

Modulation Source

Press [Mod] >
internal Source
When internal modulation source is selected, the modulating waveform is set as a
Square with 50% duty cycle, and the rate at which the output amplitude "shifts" between
"carrier amplitude" and "modulating amplitude" is determined by "ASK Rate".
external Source
When external modulation source is selected, the generator receives the external
modulating signal from the [FSK/Trig/Sync/Extmod] connector on the rear panel.
Note: The [FSK/Trig/Sync/Extmod] connector is different when controlling ASK
and AM/FM/PM modulations externally.
