To output an FSK waveform

To output an FSK waveform
You can configure the function generator to "shift" its output frequency
between two preset values using
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 the rear-panel FSK
terminal. For this example, you will set the "carrier" frequency to 3 kHz and
the "hop" frequency to 500 Hz, with an FSK rate of 100 Hz.
1 Select the function, frequency, and amplitude of the carrier.
For the carrier waveform, you can select a sine, square, triangle, ramp,
or arbitrary waveform. For this example, select a 3 kHz sine wave with
an amplitude of 5 Vpp .
