Sync Mode
Set the output mode of the sync signal on the [Sync] connector at the front panel
to normal or carrier.
Press Utility  CH1Set  SyncMode to select "Normal" or "Carrier".
 Normal: there are default operations for the [Sync] output. The operations
differ for different operation modes.
 Carrier: only available in basic waveform mode (except noise and DC) and
infinite Burst mode. When the sync polarity is positive, [Sync] output is high
level within the first half of the period and is low level within the second half of
the period. When the sync polarity is negative, the [Sync] output is reverse
to that when the sync polarity is positive.
Output Polarity
Set the signal on the [Output1] connector as normal or inverted. Waveform
inverts relatively to the offset voltage.
Press Utility  CH1Set  Output to select "Normal" or "Invert". The default is
"Normal". In normal mode, the waveform is output normally; in invert mode, the
waveform is inverted and then output.
0 V Offset
0 V
Normal Invert Normal Invert
Pay attention to the following contents after the waveform is inverted:
 None of the offset voltage would change.
 Waveform is not inverted in graphic mode.
 Sync signal related to the waveform is not inverted.
