:DECoder<n>:PARallel:EDGE
Syntax
:DECoder<n>:PARallel:EDGE <edge>
:DECoder<n>:PARallel:EDGE?
Description
Set or query the edge type of the clock channel when the instrument samples the data
channel in parallel decoding.
Parameter
Name
Type
Range
Default
<n>
Discrete
{1|2}
--
<edge>
Discrete
{RISE|FALL|BOTH}
RISE
Explanation
If no clock channel is selected (:DECoder<n>:PARallel:CLK), the instrument will sample
when the channel data jumps.
Return
Format
The query returns RISE, FALL, or BOTH.
Example
:DECoder1:PARallel:EDGE BOTH /*Set the oscilloscope to sample data on any edge
of the clock channel in parallel decoding*/
:DECoder1:PARallel:EDGE? /*The query returns BOTH*/
:DECoder<n>:PARallel:WIDTh
Syntax
:DECoder<n>:PARallel:WIDTh <wid>
:DECoder<n>:PARallel:WIDTh?
Description
Set or query the data width (namely the number of bits of each frame of data) of the
parallel bus.
Parameter
Name
Type
Range
Default
<n>
Discrete
{1|2}
--
<wid>
integer
1 to 16
8
Explanation
After setting the data width using this command, send the :DECoder<n>:PARallel:BITX
and :DECoder<n>:PARallel:SOURce commands to select each bit and set the channel
source for each bit respectively.
Return
Format
The query returns an integer between 1 and 16.
Example
:DECoder1:PARallel:WIDTh 16 /*Set the data width in parallel decoding to 16*/
:DECoder1:PARallel:WIDTh? /*The query returns 16*/
