RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

8970B Noise Figure Meter Question - RF Cafe Forums

RF Cafe Forums closed its virtual doors in 2012 mainly due to other social media platforms dominating public commenting venues. RF Cafe Forums began sometime around August of 2003 and was quite well-attended for many years. By 2010, Facebook and Twitter were overwhelmingly dominating online personal interaction, and RF Cafe Forums activity dropped off precipitously. Regardless, there are still lots of great posts in the archive that ware worth looking at. Below are the old forum threads, including responses to the original posts.

Hello all and thanks for reading.

If I set the 8970B Noise Figure Meter to one specfic frequency (say 500MHz) and I have no filtering in the test path, what is the operating bandwidth of the instrument? Lets assume the unit under test is a wide band device designed for 500MHz.

I looked in the operating manual and all I could find is that it's resolution is 1MHz but I do not believe that's the BW.

Thanks in advance.
