• 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.
To use waveform generator logic presets
With logic level presets, you can easily set the output voltage to TTL, CMOS
(5.0V), CMOS (3.3V), CMOS (2.5V), or ECL compatible Low and High levels.
1 If the Wave Gen menu is not currently displayed on the oscilloscope's softkeys,
press the [Wave Gen] key.
2 In the Wave Gen menu, press the Settings softkey.
3 In the Wave Gen Settings menu, press the Logic Presets softkey.
4 In the Wave Gen Presets menu, press one of the softkeys to set the generated
signal's Low and High voltages to logic compatible levels:
