:LA:BUS<n>:POLarity
Command format：

:LA:BUS<n>:POLarity
:LA:BUS<n>:POLarity
Functional description：

This command is used to set LA bus bit order of the oscilloscope, that is data polarity.
<n>: integer data {1|2}, it respectively represents bus 1~2.
NEGative represents bit order is from high to low; POSitive represents bit order from low to high.
Return format：

Query returns {NEGative|POSitive}.
For example：

:LA:BUS1:POLarity
:LA:BUS1:POLarity
:LA:BUS<n>:NREJect
Command format：

:LA:BUS<n>:NREJect
:LA:BUS<n>:NREJect
Functional description：

This command is used to turn on/off LA bus parallel decoding noise reject function of the oscilloscope.
<n>: integer data {1|2}, it respectively represents bus 1~2.
Return format：

Query returns 1 or 0, it respectively represents ON or OFF.
For example：

:LA:BUS1:NREJect
Turn on LA bus parallel decoding noise reject function.
:LA:BUS1:NREJect
:LA:BUS<n>:NRTime
Command format：

:LA:BUS<n>:NRTime
:LA:BUS<n>:NRTime
Functional description：

This command is used to set LA bus parallel decoding noise reject time. The default unit is s.
<n>: integer data {1|2}, it respectively represents bus 1~2.
Return format：

Query returns noise reject time, unit is s.
For example：

:LA:BUS1:NRTime
Set set LA bus parallel decoding noise reject time to 50us.
