To set the CH2 channel output parameters, select CH2 (refer to "To Select Output Channel") and then set the channel according to the descriptions in this section.
Page 112 RIGOL Chapter 2 Front Panel Operations Note: When the waveform is inverted, the sync signal related to the waveform is not inverted. To set the invert of the sync signal, tap SyncSet  Polarity to select "Negative". 3. Output Impedance The output impedance setting affects the output amplitude and DC offset.
