Remarks
 Noise rejection can remove the data that last not enough time on the bus and
eliminate the burst glitch in the actual circuit.
 When the noise rejection is enabled, send the :BUS<n>:PARallel:NRTime
command to set the required rejection time.
Return
Format
The query returns 1 or 0.
Example
:BUS1:PARallel:NREJect ON /*Enables the noise rejection function.*/
:BUS1:PARallel:NREJect? /*The query returns 1.*/
:BUS<n>:PARallel:NRTime
Syntax
:BUS<n>:PARallel:NRTime <time>
:BUS<n>:PARallel:NRTime?
Description
Sets or queries the noise rejection time of Parallel decoding. The default unit is s.

Return
Format
The query returns the noise rejection time in scientific notation.
Example
:BUS1:PARallel:NRTime 0.01 /*Sets the noise rejection time to 10 ms.*/
:BUS1:PARallel:NRTime? /*The query returns 1.000000E-2.*/
