172 Keysight M8070A Programming Guide
5 SCPI Command Reference
Description This command enables/disables the low frequency periodic jitter source.
This SCPI is applicable for M8041A, M8051A, M8061A, M8062A and
M8045A.
Example :JITT:LFR:PER ‘M1.ClkOut’, off
[:SOURce]:JITTer:LFRequency:PERiodic:AMPLitude[?]
Syntax [:SOURce]:JITTer:LFRequency:PERiodic:AMPLitude ‘identifier’, <NRf>
[:SOURce]:JITTer:LFRequency:PERiodic:AMPLitude? ‘identifier’
Input
Parameters
‘identifier’: 'M*.DataOut1', 'M*.DataOut2', M1.ClkOut’, or ‘M*.DataOut’
<NRf>: Set periodic low frequency jitter amplitude.
Return Range NRf
Description This command sets the amplitude of the periodic low frequency jitter in
unit intervals or time for the specified output. The units are set using the
[:SOURce]:JITTer:LFRequency:UNIT command.
This SCPI is applicable for M8041A, M8051A, M8061A, M8062A and
M8045A.
Example :JITT:LFR:PER:AMPL ‘M2.DataOut2’, 1
[:SOURce]:JITTer:LFRequency:PERiodic:FREQuency[?]
Syntax [:SOURce]:JITTer:LFRequency:PERiodic:FREQuency ‘identifier’, <NRf>
[:SOURce]:JITTer:LFRequency:PERiodic:FREQuency? ‘identifier’
Input
Parameters
‘identifier’: 'M*.DataOut1', 'M*.DataOut2', M1.ClkOut’, or ‘M*.DataOut’
<NRf>: Set periodic jitter frequency.
Return Range NRf
Description This command sets the frequency of the periodic jitter. Acceptable units
include Hz, kHz, MHz and exponents (for example, 1E3 is the same as
1,000 Hz).
This SCPI is applicable for M8041A, M8051A, M8061A, M8062A and
M8045A.
Example :JITT:LFR:PER:FREQ ‘M2.DataOut2’, 1e6
