:DECoder<n>:PARallel:CLK
Syntax :DECoder<n>:PARallel:CLK <clk>
:DECoder<n>:PARallel:CLK?
Description
Set or query the CLK channel source of parallel decoding.
Parameter
Name
Type
Range
Default
<n>
Discrete
{1|2}
--
<clk> Discrete {CHANnel1|CHANnel2|OFF} CHANnel1
Return
Format
The query returns CHAN1, CHAN2, or OFF.
Example
:DECoder1:PARallel:CLK CHANnel1 /*Set the CLK channel source of parallel
decoding to CH1*/
:DECoder1:PARallel:CLK? /*The query returns CHAN1*/
: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.
