Phase noise measurement with Spectrum Analyzer - RF Cafe Forums

The original RF Cafe Forums were shut down in late 2012 due to maintenance issues - primarily having to spend time purging garbage posts from the board. At some point I might start the RF Cafe Forums again if the phpBB software gets better at filtering spam.

The simplest way to make phase noise measurements with a spectrum analyser will be detailed in John Miles website at :

http://www.speakeasy.org/~jmiles1/ke5fx/gpib/pn.htm

Look at the section on PN.EXE for info on making the measurements. In
particular, follow the link in the PN.EXE information to the HP Application Note AN 270-2. Phase noise measurements couldn't be easier! I have a TEK 495P analyser and use a GPIB-to-USB dongle (see link for dongle information below).

With the dongle providing the interface between my analyser and my desktop or laptop, and using John Miles PN.EXE software, phase noise measurements are amazingly quick and easy. The dongle will work with a wide assortment of analysers- check the list to see if yours is included.
