: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*/
