ASK Rate
When internal modulation source is selected, press [Mod] >
at which the output amplitude shifts between "carrier amplitude" and "modulation
amplitude".
⚫
Use the numeric keypad or direction keys and knob to input the desired rate value.
⚫
The rate range is from 2mHz to 1MHz and the default is 100Hz.
Note: This menu will be grayed out and disabled when the external modulation
source is selected.
8.5.6
Modulation Amplitude
After enabling ASK modulation function, press [Mod] >
modulation amplitude.
⚫
Use the numeric keypad or direction keys and knob to input the desired amplitude
value.
⚫
The range of amplitude (HighZ) is from 2mV to 20V and the default is 100mV.
8.6
FSK Modulation
Users can configure the instrument to "shift" its output frequency between two preset
values using FSK modulation. The rate at which the output shifts between the two
frequencies (called the "carrier frequency" and the "hop frequency") is determined by
the internal signal level of the instrument or the signal level on the
[FSK/Trig/Sync/Extmod] connector on the rear panel.

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

Carrier Waveform Shape
FSK carrier shape: Sine (default), Square, Ramp, Pulse, Arbitrary (except DC) or
Harmonic waveform.
