16 Waveform Generator
To add noise to the waveform generator output
1 If the Waveform Generator Menu is not currently displayed on the
oscilloscope's softkeys, press the [Wave Gen] key.
2 In the Waveform Generator Menu, press the Settings softkey.
3 In the Waveform Generator Settings Menu, press the Add Noise softkey
and turn the Entry knob to select the amount of white noise to add to
the waveform generator output.
Note that adding noise affects edge triggering on the waveform generator
source (see "Edge Trigger" on page 115) as well as the waveform generator
sync pulse output signal (which can be sent to TRIG OUT, see "Setting the
Rear Panel TRIG OUT Source" on page 246). This is because the trigger
comparator is located after the noise source.
To add modulation to the waveform generator output
Modulation is where an original carrier signal is modified according to the
amplitude of a second modulating signal. The modulation type (AM, FM, or
FSK) specifies how the carrier signal is modified.
To enable and set up modulation for the waveform generator output:
1 If the Waveform Generator Menu is not currently displayed on the
oscilloscope's softkeys, press the [Wave Gen] key.
2 In the Waveform Generator Menu, press the Settings softkey.
