Phase Noise and Relevance to the EMC Standards - RF Cafe Forums

Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.

Below are all of the forum threads, including all the responses to the original posts.

Hello,

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:
1.Frequency error.
2.Carrier Power
3.Adjacent channel power.
4.Frequency deviation.
5.Spurious emissions
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 standard?

Thankyou

Hello Darcy,

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 and safety.
