| EVM system design/calculation - 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.

Input: Should be data like drive level, phase/amplitude ripple in filter, compression point of amplifier and frequency error in mixer Output: EVM Sincerely/Pär Top Profile Guest Post subject: EVM Unread postPosted: Mon Jun 13, 2005 12:59 pm Most "budgets" have an assumption of linearity hiding in them somewhere. The essence of EVM is that the greatest portion results from non-linearity. In fact, the EVM of a signal from different amplifiers with the same third-order intercept point can vary significantly. Good Luck (and I think you'll need it) ! Top Guest Post subject: Unread postPosted: Mon Jun 13, 2005 1:15 pm Try systemview from eaglware-elanix Posted 11/12/2012 | ||||||
