RF frequency sweep
« on: November 11, 2014, 04:57:16 pm »

What's your favorite device for measuring ambient RF energy across wireless mic spectrum?
The application is to find best RF band for an installed wireless mic system at a sports field.

If you are looking for something cheap and a little clumsy, there is freeware available to make $20 usb dtv dongles act as a spectrum analyser....

Hi Pete,
Thanks for your help and expertise!
Do you have a suggestion on where to purchase the TTi?  Seems not many sell via internet search...

Excellent, but much more than someone working with mics and IEMs needs.

You only need coverage for the frequencies you are interested in.  And in many situations you really don't need one.

You want something that will record peak and average spectrum plots over time.  You want something cheap enough that you can leave it unattended at a venue for 24 hours.

Not all sources of interference transmit all the time.
