3FSK
When 3FSK (3 Frequency Shift Keying) modulation is selected, you can configure
the generator to "shift" its output frequency among three preset frequencies
("carrier frequency" and two "modulating frequencies"). The "shift" frequency
(3FSK rate) is determined by the internal signal level of the instrument.
To Select 3FSK Modulation
Press
Mod

Type

3FSK to enable 3FSK function.

When Mod is enabled, Sweep or Burst will be automatically disabled (if
enabled currently).

After 3FSK is enabled, the instrument will generate 3FSK waveform with the
currently specified carrier and modulating waveforms.
To Select the Carrier Waveform Shape
3FSK carrier waveform could be Sine, Square, Ramp or arbitrary waveform (except
DC), and the default is Sine.

Press the front panel key
Sine, Square, Ramp or Arb

Select Wform
(or User, the pre-defined waveform cannot be DC) to select desired carrier
waveform shape.

Pulse (basic waveform), Noise and DC could not be used as carrier waveform.
To Set the Carrier Frequency
Different carrier waveforms have different frequency ranges as shown in the table
below. For all the carrier waveforms, the default value is 1kHz.
