RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while tying up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...

Phase Noise and Relevance to the EMC Standards - RF Cafe Forums
RF Cafe Forums closed its virtual doors in 2012 mainly due to other social media
platforms dominating public commenting venues. RF Cafe Forums began sometime around
August of 2003 and was quite well-attended for many years. By 2010, Facebook and
Twitter were overwhelmingly dominating online personal interaction, and RF Cafe
Forums activity dropped off precipitously. If the folks at
phpBB would release a version with integrated
sign-in from the major social media platforms, I would resurrect the RF Cafe Forums,
but until then it is probably not worth the effort. Regardless, there are still
lots of great posts in the archive that ware worth looking at.
Below are the old forum threads, including responses to the original posts.

With regards to my paging transmitter -
I have taken a look
at the standard AS NZS 4769 Radiocommunications equipment used in the
paging service - Angle modulated equipment.
The standard lists
a number of requirements regarding transmitter behaviour:
3.Adjacent channel power.
6.Transmitter transient behaviour.
Which of these requirements is directly related to phase noise?
Otherwise can I expect to find a requirement for phase noise in another

To my understanding except parameter #6, none
of them is directly related to phase-noise. Phase noise is usually given
as a specification for the product/component itself (As a stand-alone
unit) and has no impact on standards for regulation such as for EMC
