To specify the expected output load
1 If the Waveform Generator Menu is not currently displayed on the
2 In the Waveform Generator Menu, press the Settings softkey.
3 In the Waveform Generator Settings Menu, press the Out Load softkey
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.

Sync Signal Characteristics
The Sync signal is a TTL positive pulse that occurs when the waveform
rises above zero volts (or the DC offset value).
