What is frequency in this device?

In north america all z-wave devices use the 900mhz band, which means it won't interfere with wifi, baby monitors, etc, which use the 2.4ghz band.

You have to look inside the main unit and determine what the frequency is set on- 7k or 10k. I assume your on 7k . There's a way to switch it from 7 to 10

I did the tests on other devices, but apparently the devices use different frequencies.

I believe these are the operating frequencies that are available. You can find the details at the Shure website.

No frequency isn't an issue. Just need one that converts 120 into 240. There are plenty around for cheap that will do the job.

The company does not state what frequency this thing transmits on. At least not that I could find anywhere. In actual practice, it's operating frequency is: Every time I've used it

I have to say fixed frequency , I think it runs in the 660 to 880 MHz range depends on what else you use in that range, even then what are the odds of anything being on that same freq.

good question, I am not sure since I only have one unit. But I think the frequency might be different so it might not work.

I have no idea. You can probably research what FREQ they both use. Sorry, don't know.

You have to use the app to change frequencies. There's no other way to communicate with the module.

I really don't know what the frequency is, but I had the exact same situation! I also bought a Krohn for my Dad. He also could not hear it. I bought this one, and we set it to lowest frequency and played with the tones to get it right for him. When we customized the settings for him, which was an fast-easy process, he could hear the phone ring even when he was outside!

The sampling rate should be at least twice the data rate according to Shannon's Law. I haven't checked it on high frequency devices over 5 MHz. or so. The proof of the picking would to be if it would display the output from a signal generator or a random antenna connected to it and transmitting nearby within the 20 or 30 meter bands. I don't recall saying it had a 72 MHz. bandwidth, if it did, everybody would have one and they wouldn't be as cheaply priced. Check out the print on the website and there might be a detail or two: Sain DSO (oh--not zero,)203. I haven't used mine in a while, I just like gadgets, fool around with them for a while until I get bored or figure out a better way to do the same thing. Good luck...

I have not had any problems with the meter, I am not sure what you are wanting to check the frequency of, but I use it on HVAC equipment and check frequency once in a while and it works for checking that.

The manual , unfortunately is written in Chinglish, and they are probably referring to a much higher frequency, and this stateme t made it past the spell checkers & context checkers. Otherwise the other answers proffered for this are certainly valid, referringto 50Hz, AC Line interference & aliasing, from domestic Japanese , Chinese, & UK sources of 50 Hz power & frequency deviation..

I guess you would have to verify what frequesncy is available. This is Quadband and quite useful in most countries.

The meter displays in dBC, frequency range of 31.5Hz-8KHz. Meter works great. Nice compact design.

I have had many devices like this and there never was a way to change the frequency. I made a mistake once in purchasing two remote control cars of the same frequency. There was no way it could be done.
