- I know I said I wasn’t going to do a review of this, but thought some of you would like to see the Start-Up of this unit.

Thanks for the effort. I just wonder why you used 0.1S gate time rather than 1S or even 10S to compare results? I've been comparing mine to a GPS reference and I'm quite impressed.
I found these specifications on an Ali Express ad.

had you printed on both sides of the paper you culd have condensed it even more lol
Thanks for the video always helpful to have another view of the instrument, seems to be well constructed and as you say would be good to have a manual with codes etc. Is there any way to battery power as an option I wonder? One of the web pages gives this as an option. The low frequency cut-off is probably due to the input coupling capacitor, so adding a parallel one on CH2 would lower it to be more in specification?
Hello, what is the maximum voltage (or amplitude) of a signal that the BGT7TBL FA-3 (or FA-2) frequency counter can handle? I would appreciate your support a lot!
Hi there, Can I use any of these frequency meters to measure EMF (up to 30Ghz) connected directly to a passive microwave antenna? I´m interested in measuring the millimetric 5G radiation received in my home and I don´t want to spend thousand of euros in a professional EMF device.
Not that I know of.

I just checked on eBay and there is a bunch o FA-3 for a decent price. All from China.
