Web Site Down

The web site, spectrumanalyzer.com is down. I am trying to contact our benefactor and owner who has provided his server for our web site for all these years. It is possible that the site will be moved. We have an offer from another of our members if our original site is lost.

Win 8 and USB

Upon starting his MSA software, it would sweep a few times and then the Magnitude would drop to -120 dBm. It would continue sweeping at that level and give no errors. Halting and...

Re: 1 GHz super narrow bandwidth

<t>Hi Deval and All,<br/> &nbsp; An interesting question. Cavities with Q's higher than 50,000 have been built and documented, but all I have seen have been used as an oscillator element. Most of them are made from rare superconductor material and ruby coated resonators, and operated at temperat...
