Explanation Before sending this command, use the :DECoder<n>:PARallel:BITX command to select
the desired data bit.
Return
Format
The query returns CHAN1 or CHAN2.
Example
:DECoder1:PARallel:SOURce CHANnel2 /*Set the channel source of the current bit to
CH2*/
:DECoder1:PARallel:SOURce? /*The query returns CHAN2*/

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
:DECoder1:PARallel:POLarity NEGative /*Set the data polarity of parallel decoding to
negative*/
:DECoder1:PARallel:POLarity? /*The query returns NEG*/
:DECoder<n>:PARallel:NREJect
Syntax :DECoder<n>:PARallel:NREJect <bool>
:DECoder<n>:PARallel:NREJect?
Description Turn on or off the noise rejection function of parallel decoding, or query the status of the
noise rejection function of parallel decoding.
Parameter
Name Type Range Default
<n> Discrete {1|2} --
<bool> Bool {{1|ON}|{0|OFF}} 0|OFF
Explanation  Noise rejection can remove the data without enough duration on the bus to
eliminate the glitches of the actual circuit.
