<IP_Noise>::=<NRf>
is the integrated phase noise in radians or degrees.
<Rj>::=<NRf>
is the random jitter in seconds.
<Max_Pj>::=<NRf>
is the maximum periodic jitter in seconds.
<Jstime>::=<NRf>
is the jitter settling time in seconds.
<Jsstart>::=<NRf>
is the jitter settling time start in seconds.

<Fstime>,<Fsstart>,<Fsstop>,<TFstime>,<Tfsstart>,<Tfsstop>
Where
<Fstime>::=<NRf>
is the frequency settling time.
<Fsstart>::=<NRf>
is the frequency settling time start.
<Fsstop>::=<NRf>
is the frequency settling time stop.
<TFstime>::=<NRf>
