:DECoder<n>:PARallel:POLarity
Syntax :DECoder<n>:PARallel:POLarity <pol>
:DECoder<n>:PARallel:POLarity?
Description
Set ro query the data polarity of parallel decoding.
Parameter
Name Type Range Default
<n>
Discrete
{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
: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.
 When the noise rejection is turned on, sending the
:DECoder<n>:PARallel:NRTime
command can set the desired rejection time.
Return
Format
The query returns 1 or 0.
Example :DECoder1:PARallel:NREJect ON /*Turn on the noise rejection function*/
:DECoder1:PARallel:NREJect? /*The query returns 1*/
