CW measurements - 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.

Dear Friends,

I'm in a big problem, I must perform a CW "continues wave' drive test for UMTS model tuning project for 40 sites and I must start in two days.
I know how to perform 2G (GSM) drive test but the CW drive test is a new for me.

So, please please could you describe the drive test process for the CW in steps, I will use W-CDMA Area Tester for this drive test.

Please, it's not only important but it's a very urgent.
I'm sure you could help me.

Waiting your reply ASAP.

It sounds to me like you need to radiate an unmodulated carrier from each BTS, and with a spectrum or transmission analyzer and GPS linked to a laptop, drive out radially recording the CW carrier level. Suitable software then translates the data into a map overlay to produce carrier level contours for each BTS.
I guess this has to be done for each carrier, but the test spec should state this.
