Gain Flatness - 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.

I have a measurement that I am not familiar with. I have been asked to perform a Gain Flatness measurement over a frequency range.

I am measuring a coax cable with 2 connectors.

What type of meausrement is Gain Flatness ? How would I set up the VNA ?

Gain flatness of any applicable device is defined as the variation of a transmission characteristic (S21) over the full operational frequency range, usually at a given temperature, expressed in dB.

Take Care
