drplJitter function help

Hi,

When running pmjitter based phase noise measurement. The drplJitter function is used to obtain a sec/sqrt(Hz) plot. Where can I find help for this function?

drplJitter(?result "pnoise_pmjitter" ?unit "Second" ?k 1 ?event 0)

1) What does "k" represent in the above function?

2) Is there a way to obtain SSB phase noise plot in dBc/Hz using pmjitter?

Thanks
