 :BUS<n>:PARallel:WIDTh
 :BUS<n>:PARallel:BITX
 :BUS<n>:PARallel:SOURce

:BUS<n>:PARallel:CLK
Syntax
:BUS<n>:PARallel:CLK <source>
:BUS<n>:PARallel:CLK?
Description
Sets or queries the clock source of the Parallel decoding.
Parameter
Name
Type
Range
Default
<n>
Discrete
{1|2|3|4}
——
<source>
Discrete
{D0|D1|D2|D3|D4|D5|D6|D7|D8|
D9|D10|D11|D12|D13|D14|D15|
CHANnel1|CHANnel2|CHANnel3|CHANnel4|
OFF}
OFF
Return
Format
The query returns D0, D1, D2, D3, D4, D5, D6, D7, D8, D9, D10, D11, D12, D13, D14,
D15, CHAN1, CHAN2, CHAN3, CHAN4, or OFF.
Example
:BUS1:PARallel:CLK D0 /*Sets the clock source of the Parallel decoding to D0.*/
:BUS1:PARallel:CLK? /*The query returns D0.*/
:BUS<n>:PARallel:SLOPe
Syntax
:BUS<n>:PARallel:SLOPe <slope>
:BUS<n>:PARallel:SLOPe?
Description
Sets or queries the edge type of the clock channel when being sampled by Parallel
decoding on the data channel.
Parameter
Name
Type
Range
Default
<n>
Discrete
{1|2|3|4}
——
<slope>
Discrete
{POSitive|NEGative|BOTH}
POSitive
Remarks
If no clock channel is selected, the instrument will sample when the channel data
jumps during the decoding.
Return
Format
The query returns POS, NEG, or BOTH.
