To Output an FSK Waveform
You can configure the function generator 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 the rear-panel Trig In connector. 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.
Press and then press the Freq, Ampl, and Offset softkeys to
configure the carrier waveform.
For this example, select a 3 kHz sine wave
with an amplitude of 5 Vpp.
2 Select FSK.
Press and then select “FSK” using the Type softkey. Notice that a
status message “FSK” is shown in the upper-left corner of the display.
