<CsNcs> Discrete {NCS|CS} NCS
Explanation
 NCS: low level is valid (
). The instrument starts transmitting data when the
CS is low.
 CS: high level is valid (
). The instrument starts transmitting data when the
CS is high.
 This command is only valid in the CS mode (:DECoder<n>:SPI:MODE).
Return
Format
The query returns NCS or CS.
Example
:DECoder1:SPI:SELect CS /*Set the CS polarity to high level is valid*/
:DECoder1:SPI:SELect? /*The query returns CS*/
