Explanation
This command is only valid in the CS mode (:DECoder<n>:SPI:MODE).
Return
Format
The query returns D0, D1, D2, D3, D4, D5, D6, D7, D8, D9, D10, D11, D12, D13, D14,
D15, CHAN1, CHAN2, CHAN3, or CHAN4.

{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*/
