:OUTPut[]:SYNC:POLarity
Syntax :OUTPut[]:SYNC:POLarity {POSitive|NEGative}
:OUTPut[]:SYNC:POLarity?
Description Set the output polarity of the sync signal on the [Mod/Trig/FSK/Sync] connector
of the specified channel at the rear panel to normal (POSitive) or inverted
(NEGative).
Query the output polarity of the sync signal on the [Mod/Trig/FSK/Sync]
connector of the specified channel at the rear panel.
Parameter Name Type Range Default
[] Discrete 1|2 1
{POSitive|NEGative} Discrete POSitive|NEGative POSitive
Explanation  When [] is omitted, the commands set and query the related parameters of
CH1 by default.
 The output polarity of the sync signal refers to that the sync signal on the
[Mod/Trig/FSK/Sync] connector of the channel at the rear panel is normal
(POSitive) output or inverted (NEGative) output. In the normal mode, the
instrument outputs the sync signal normally and in the inverted mode, the sync
signal is inverted and then outputted.
 After the waveform is inverted ( :OUTPut[]:POLarity ), the sync signal related
to the waveform will not be inverted.
Return Format The query returns POS or NEG.
Example :OUTP1:SYNC:POL POS /*Set the output polarity of the sync signal on the
[Mod/Trig/FSK/Sync] connector of CH1 at the rear
panel to normal */
:OUTP1:SYNC:POL? /*Query the output polarity of the sync signal on the
[Mod/Trig/FSK/Sync] connector of CH1 at the rear
panel and the query returns POS*/
