Features and Function
HDG2000 Series Arbitrary Waveform Generator 38
SCPI:
SOURce<n>:MOD:PM:DEViation <deviation>|MINimum|MAXimum
Modulating Source
The instrument accepts an internal, external or external trig modulation source.
Modulating source: Internal (default), Other Channel, or External. The External modulation
source may be up to 100 kHz.
With the External source, the carrier waveform is modulated with an external waveform. The ±5
V signal level present on the front-panel Mod connector controls the phase deviation.
When the External Trig source is selected, the +5 V signal level present on the front-panel TRIG
connector controls the phase deviation.

3.5 Frequency-Shift Keying (FSK) Modulation
You 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 rate generator or the
signal level on thefront-panel TRIG connector.
To Select FSK Modulation

Only one modulation mode may be enabled at a time. Enabling FSK turns off the previous
