| | Signal Network Analyzer - 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.

| | Very simple, take the ad8302 from analog devices, and you are almost done.
Add a directional coupler, a Rf signal source and thats it.
For more details see the ad8302 datasheet.
Maybe u would like to order the evaluation board...

| | hi all,
is there a user group for the ad8302 anywhere ?
i bought the eval bd from analog devices and use
it often. and want to visit with other users
the closest thing i have found is a yahoo group
that uses the 8302 with a 9851 dds and some s/w

Location: Hampshire UK | Unfortunately, the AD8302 method of measuring phase is not very accurate near the match ( 0 degree and 180 degree). Also, it works best with signals that are both nearly the same. So you need a lot of ways to contrive this, and to keep account of attenuators and gains.
I am sure it can be useful, especially in transmitter monitoring and in control loops, and even to be the heart of a cheaper network analyser, but I am thinking that real industry network analysers are unaffordable to guys like me for a reason.
