[:SOURce[<n>]][:MOD]:PSKey:POLarity
Syntax [:SOURce[<n>]][:MOD]:PSKey:POLarity {POSitive|NEGative}
[:SOURce[<n>]][:MOD]:PSKey:POLarity?
Description Set the PSK modulation polarity of the specified channel to positive (POSitive) or
negative (NEGative).
Query the PSK modulation polarity of the specified channel.
Parameter Name Type Range Default
[<n>] Discrete 1|2 1
{POSitive|NEGative} Discrete POSitive|NEGative POSitive
Explanation  When [:SOURce[<n>]] or [<n>] is omitted, the system sets the related
parameters of CH1 by default.
 In internal modulation ( [:SOURce[<n>]][:MOD]:PSKey:SOURce ), the signal
generator would output the carrier phase when the modulating waveform is logic
low level and output the modulation phase
( [:SOURce[<n>]][:MOD]:PSKey:PHASe ) when the modulating waveform is logic
high level if the polarity is set to positive. The situation is the opposite when the
polarity is set to negative.
 In external modulation ( [:SOURce[<n>]][:MOD]:PSKey:SOURce ), the signal
generator would output the carrier phase when the external input signal is logic
low level and output the modulation phase
( [:SOURce[<n>]][:MOD]:PSKey:PHASe ) when the external input signal is logic
high level if the polarity is set to positive. The situation is the opposite when the
polarity is set to negative.
Return Format The query returns POS or NEG.
Example :SOUR1:PSK:POL POS /*Set the PSK modulation polarity of CH1 to positive*/
:SOUR1:PSK:POL? /*Query the PSK modulation polarity of CH1 and the query
returns POS*/
