SCPI Command Reference
5
Example
The below mentioned SCPI command sets the method used to modulate
clock frequency and data to ‘DOWN’ for M8041A/M8045A:
:SSCL:TYPE ‘M1.ClkGen’, DOWN
The below mentioned SCPI command queries the method used to
modulate clock frequency and data for M8041A/M8045A:
:SSCL:TYPE? ‘M1.ClkGen’
DOWN
[:SOURce]:SSCLocking:PROFile[?]
Syntax
[:SOURce]:SSCLocking:PROFile ‘identifier’, <TRIangular|ARBitrary>
[:SOURce]:SSCLocking:PROFile? ‘identifier’
Input
Parameters
‘identifier’: 'M1.ClkGen'
<TRIangular|ARBitrary>: Set spread spectrum clocking profile.
Return Range
TRI|ARB
Description
This command sets up the spread spectrum clocking (SSC) using a
triangular or arbitrary profile.
This SCPI is applicable for M8041A and M8045A.
It is also applicable for M8195A but only in query mode.
Example
:SSCL:PROF ‘M1.ClkGen’,TRI
[:SOURce]:SSCLocking:SHAPe[?]
Syntax
[:SOURce]:SSCLocking:SHAPe ‘identifier’, <“Filename”>
[:SOURce]:SSCLocking:SHAPe? ‘identifier’
Input
Parameters
‘identifier’: 'M1.ClkGen'
<“Filename”>: Set up spread spectrum clocking shape specified in
“Filename”.
Return Range
“Filename”
Description
This command sets up the spread spectrum clocking (SSC) using the
specified shape in “Filename”. A simple text file contains the data points
which define the arbitrary waveform of the SSC profile.
