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.

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 Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...
