Waveform Generator
3 In the Waveform Generator Settings Menu, press the Trig Out softkey and
turn the Entry knob to select Waveform Generator Sync Pulse .
To specify the expected output load
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
Out Load
softkey
and turn the Entry knob to select:
• 50
Ω
•
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.

Waveform Type Sync Signal Characteristics
All waveforms except
DC, Noise, and
Cardiac The Sync signal is a TTL positive pulse that occurs when the waveform
rises above zero volts (or the DC offset value).
