5 SCPI Command Reference
[:SOURce]:SSCLocking:DEViation[?]
Syntax [:SOURce]:SSCLocking:DEViation ‘identifier’, <NRf>
[:SOURce]:SSCLocking:DEViation? ‘identifier’
Input
Parameters
‘identifier’: 'M1.ClkGen'
<NRf>: Set spread spectrum clocking deviation.
Return Range 0% to 1%
Description This command sets the spread spectrum clocking (SSC) deviation in
percent. The effective deviation is ±0.5% (or 1% peak-to-peak).
This SCPI is applicable for M8041A, M8195A, M8196A and M8045A.
Example The below mentioned SCPI command sets the spread spectrum clocking
(SSC) deviation to ‘0.2’ percent for M8041A/M8045A:
SSCL:DEV ‘M1.ClkGen’, 0.2
The below mentioned SCPI command queries the spread spectrum
clocking (SSC) deviation for M8041A/M8045A:
SSCL:DEV? ‘M1.ClkGen’
0.2
[:SOURce]:SSCLocking:TYPE[?]
Syntax [:SOURce]:SSCLocking:TYPE ‘identifier’,
<DOWNspread|UPSPread|CENTerspread>
[:SOURce]:SSCLocking:TYPE? ‘identifier’
Input
Parameters
‘identifier’: 'M1.ClkGen'
<DOWNspread|UPSPread|CENTerspread>: Set spread spectrum clocking
type.
Return Range DOWN|UPSP|CENT
Description This command sets method used to modulate the clock frequency and
data. Choose between center spread, down spread, or up spread.
This SCPI is applicable for M8041A, M8095A and M8045A.
It is also applicable for M8195A but only in query mode.
