Agilent Technologies 33120A User Manual

To output an FSK waveform
You can configure the function generator to “shift” its output frequency
between two preset values using
FSK (frequency-shift keying) 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 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.
2Enable FSK.
Notice that the
FSK annunciator turns on.
3 Use the menu to set the “hop” frequency.
After you enable the
FSK mode, the “recall menu” key will automatically
take you to the
FSK FREQ command in the MOD MENU.
