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).
