JITTer:PJRMS?
JITTer:PJRMS?
Query :MEASure:JITTer:PJRMS?
Returns the periodic jitter value, RJ (rms), measured on the current source.

Returned Format [:MEASure:JITTer:PJRMS] <value><NL>
Example 10 OUTPUT 707;”:SYSTEM:HEADER OFF”
20 OUTPUT 707;”:MEASure:JITTer:PJRMS?”
JITTer:RJ?
Query :MEASure:JITTer:RJ?
Returns the random jitter value measured on the current source.
Restrictions Jitter mode. Software revision A.04.00 and above (86100C instruments).
Returned Format [:MEASure:JITTer:RJ] <value><NL>
Example 10 OUTPUT 707;”:SYSTEM:HEADER OFF”
20 OUTPUT 707;”:MEASURE:JITTER:RJ?”
JITTer:RJSTabilize
Command :MEASure:JITTer:RJSTabilize {{OFF | 0} | {ON | 1}}
Turns RJ stabilization on or off. RJ Stabilization locks the value of the measured RJ. Use RJ
stabilization to prevent any uncorrelated non-Gaussian, non-periodic jitter from falsely con-
tributing to any measured RJ value. This requires a two-part measurement. First, remove any
sources of uncorrelated non-Gaussian, non-periodic jitter (for example, crosstalk or non-peri-
odic electromagnetic interference), set RJ stabilization off and measure the RJ. Then, turn RJ
stabilization on and reapply the sources of uncorrelated non-Gaussian, non-periodic jitter.
One use of RJ stabilization is to prevent crosstalk, from an adjacent channel, appearing as jit-
ter.
Use the MEASure:JITTer:RJSValue command to set or query the stabilization value.
Restrictions Jitter mode. Software revision A.04.20 and above (86100C instruments).
Query :MEASure:JITTer:RJSTabilize?
Returned Format [:MEASure:JITTer:RJSTabilize] {{OFF | 0} | {ON | 1}}<NL>
Example 10 OUTPUT 707;”:SYSTEM:HEADER OFF”
20 OUTPUT 707;”:MEASURE:JITTER:RJSTABILIZE ON”
JITTer:RJSValue
Command :MEASure:JITTer:RJSValue <RJ_set_num>
Sets the RJ stabilization value. Use the MEASure:JITTer:RJSTabilize command to turn RJ sta-
bilization on or off.
Restrictions Jitter mode. Software revision A.04.20 and above (86100C instruments).
Query :MEASure:JITTer:RJSValue?
This query returns the fixed RJ value for RJ stabilization.
