Waveform Generator 20
Keysight InfiniiVision HD3-Series Oscilloscopes User's Guide 253
Note that adding noise affects edge triggering on the waveform generator
source (see
"Edge Trigger" on page 137) as well as the waveform generator
sync pulse output signal (which can be sent to AUX OUT, see "Setting the
Rear Panel AUX OUT Source"
on page 282). This is because the trigger
comparator is located after the noise source.
• Output Settings... — Opens the Output Settings dialog box where you can
specify the expected output load, invert the output, and output the
waveform generator sync pulse. See
"To specify the output settings" on
page 253.
• Edit Waveform... — Opens the "To edit arbitrary waveforms" on page 254
where you can edit arbitrary waveforms.
• Modulation... — Opens the Modulation dialog box where you can add
modulation to the waveform generator output. See
"To add modulation to
the waveform generator output"
on page 257.
• Default Wave Gen — Returns the waveform generator to its default settings.
The waveform generator factory default settings (1 kHz sine wave,
500 mVpp, 0 V offset, High-Z output load) are restored.

To specify the output settings
In the Waveform Generator dialog box, click Output Settings... to open the Output
Settings dialog box.
The Output Settings dialog box has these controls:
• Output Load — The expected output load can be 50 Ω or High-Z.
The output impedance of the Gen Out BNC is fixed at 50 ohms. However, the
output load selection lets the waveform generator display the correct
amplitude and offset levels for the expected output load.
If the actual load impedance is different than the selected value, the displayed
amplitude and offset levels will be incorrect.
• Invert Output — Lets you enable or disable an inverted output.
