Description
In Jitter Mode, specifies a known specific waveform Pattern Symbol Sequence when the :MEASure:JITTer:DEFine:PATTern:MODE command has specified a known pattern instead of autodetection. The arguments used to specify the pattern are listed in the following table.
To specify the waveform's format (NRZ or PAM4), use the :MEASure:JITTer:DEFine:PATTern:FORMat command.
