1. After setting the CH1 waveform param-
eters, push the front-panel Channel
select button to select CH2.
2. Push the front-panel Top Menu
button, and then push the Output Menu
bezel button.
3. Push the CH1 Complement bezel but-
ton.
4. The CH2 waveshape and timing param-
eters are copied from CH1, and the CH2
amplitude settings are inverted from
CH1.
NOTE. When CH1 is selected in the AFG310x or AFG325x series instrument, the instrument displays External Add Off/On
in the Output menu.
