{1|2}
--
<pol>
Discrete
{NEGative|POSitive}
POSitive
Explanation
 NEGative: . The low level is 1.
 POSitive: . The high level is 1.
Return
Format
The query returns NEG or POS.
Example

Discrete
{1|2}
--
<edge>
Discrete
{RISE|FALL}
RISE
Return
Format
The query returns RISE or FALL.
Example
:DECoder1:SPI:EDGE FALL /*Set the instrument to sample data on the falling edge
of the clock in SPI decoding*/
:DECoder1:SPI:EDGE? /*The query returns FALL*/
