Chapter 2 Command System RIGOL
MSO5000 Programming Guide 2-13
Example
:BUS1:PARallel:SLOPe BOTH /*Sets the Parallel decoding to sample on any edge
of the clock channel.*/
:BUS1:PARallel:SLOPe? /*The query returns BOTH.*/
:BUS<n>:PARallel:WIDTh
Syntax
:BUS<n>:PARallel:WIDTh <wid>
:BUS<n>:PARallel:WIDTh?
Description
Sets or queries the data width of the parallel bus, i.g. the number of bits per frame.
Parameter
Name
Type
Range
Default
<n>
Discrete
{1|2|3|4}
——
<wid>
Integer
0 to 20
1
Remarks
 After you send this command to set the data width of the bus, send
the :BUS<n>:PARallel:BITX and :BUS<n>:PARallel:SOURce command to select
the bit respectively and set the channel source for the bit.
 Only when the bus source is set to User, can this command be valid.
Return
Format
The query returns an integer ranging from 0 to 20.
Example
:BUS1:PARallel:WIDTh 16 /*Sets the data width of Parallel decoding to 16.*/
:BUS1:PARallel:WIDTh? /*The query returns 16.*/
:BUS<n>:PARallel:BITX
Syntax
:BUS<n>:PARallel:BITX <bit>
:BUS<n>:PARallel:BITX?
Description
Sets or queries the data bit that the parallel bus requires to set for the channel source.
Parameter
Name
Type
Range
Default
<n>
Discrete
{1|2|3|4}
——
<bit>
Integer
0 to (data width - 1)
0
Remarks
 The data width is set by the :BUS<n>:PARallel:WIDTh command.
 After selecting the desired bit, send the :BUS<n>:PARallel:SOURce command to
set the channel source for the bit.
 The data bit should be smaller than or equal to the data width.
Return
Format
The query returns the current data bits in integer. Its unit is Hz.
Example
:BUS1:PARallel:BITX 2 /*Sets the current bit to 2.*/
:BUS1:PARallel:BITX? /*The query returns 2.*/
