ELA Posted January 6, 2023 Posted January 6, 2023 I received a small, inexpensive ( ~ $230) hand-held spectrum analyzer for Christmas that I though might be of some interest to other home automation people. Something like this is likely hard to justify purchasing for occasional use but Santa was good to me this year. I used to be a test engineer so I miss not having access to all the equipment I used to. I am attaching a few screen shots of potential uses. Top= Insteon RF signal at 2ft from On/Off switch module: Bottom= Garage Door Remote: I thought @apostolakisl might be interested in the garage door signal. I recall an issue with interference that this device could help identify. 2 1
Techman Posted January 6, 2023 Posted January 6, 2023 Interesting, what's the RF frequency range What's the model number?

It's not paranoia if they really are after you. Just sayin' . . .
Brian H Posted January 6, 2023 Posted January 6, 2023 I too have one of them. In my case I have the 240MHz to 960MHz receiver and a 15MHz to 2700MHz receiver in it. As you can use a add on board for a second receiving band. I have seen different receiving ranges in some of the assembled models and the add on board in a kit. https://rfexplorer.com/
ELA Posted January 6, 2023 Author Posted January 6, 2023 Good to hear that you also have one Brian. What sorts of things have you used yours for? Mine is the ISM Combo plus: Frequency bands: Left connector: 0.05 – 960MHz Right connector: 2350 – 2550MHz here is my microwave at 10ft on high power:
Brian H Posted January 6, 2023 Posted January 6, 2023 (edited) Mine is an earlier version. I think. As it is the plain metal case. Looks like yours has a protective covering or they changed the unit away from the bare metal case. Left 240-960MHz, I added the Right 15-2700MHz accessory board kit. So I got a nice carrying case in the kit. Firmware 01.33 I have used mine to see things like Insteon modules RF signals. They are not all exactly 915MHz. I have see some slightly higher and lower. Same for X10. Edited January 6, 2023 by Brian H
