In your video #064 I explained how to make changes on the FA-2 so I guess you just forgot in this video so I will repost it again here. As you know from our correspondence I really enjoy your channel and think you do a great job. One negative is you keep showing me things that I end up buying ; ) You are one of my favorite channels. Thanks for all the videos you create and keep them coming! Here is the repost: The 50-ohms is not fixed on CH1 as mentioned in the video. It can be changed from 50-ohm to 1-Mohm. To switch back and forth on the input impedance: First press the RST button and while holding it down press the Mode button. You should hear a relay click which I assume is removing a 50-ohm resistor in parallel with the 1-Mohm resistor. You have to repeat this procedure each time you wish to make a change. Also on CH1 you can turn on and off a LPF: First press the RST button and while holding it down press the GATE button. The LPF is very helpful on getting better triggering on low frequencies. One of the biggest problems with many inexpensive counters is that they have fair to poor trigger circuits so the LPF can be helpful although not the best fix. These features are not available on CH2.

Hi Tony, do you think we can even replace the LCD with a further bigger one .? I really want an E Ink display which would be actually awesome ... probably it would be i2C to SPI converter ...!

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.

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!

Hello, do you know how to save the last frequency setting so that when the WB-SG generator is turned off and then turned on it will keep the last setting and will not come back to the default frequency? Maybe via some ASCII code command?

gee whiz. I am starting to learn about SDR backyard radio telescopes. The 21cm 1420 MHz hydrogen-line setup recommends a counter/generator. So which one? 😎 thanks.

Well Tony not to impressed with the rf generators, OK they're probably cheap but not serious test equipment by my standards, the output was not accurate & to only go down to -40 dbm is useless for testing radios. I'll stick with my two marconis , of course they cost more but not too much second hand, thanks for the video, best wishes nick

Tony, I have the smaller model but have not used it yet. I'm close to reorganizing my workbench with the addition of additional equipment. Once things are in place for this phase, I'll test mine. Your video is motivating me to take it for a run BG7TBL has a number of very cool products!

Excellent videos! I am planning to replace my vintage Eico and Heathkit test equipment with BG7TBL stuff. My concern with Chinese equipment are FAKES. I notice BG7TBL devices are sold under various brand news such as Bulipu, Davitu and Seeku. I know they are fake tinySAs being sold that aren't as good as the real tinysa. Should I have the same concerns with BG7TBL devices?

A follow-up Q that I forgot....at the 31 minute mark, the comparison of the smaller and larger versions does have two additional parts on the right side...the silver ICs (?). Do they have markings to identify what they are?

Hello Tony, do you have by any chance any documentation how to control the WB-SG1 via the USB port ? i have found some documentation to set freq and sweep and so and that works fine, but i am missing the command to set the output level, my plan is to write a simple program to interface with it via a computer. i just need documentation.

That’s really great 👍!

What a pity for the WB-SG2 !!! it would have been perfect for tuning receivers. very disappointed

Thank you very much for the presentation. I have a question: the waveform of the signal gens I have used for RF are 'sine' but these are 'square' waves. So does it matter sine or square ? in RF applications such as aligning receivers transmitters etc ? regards

Hello. It would have been interesting to completely disassemble the devices and see the sms components located below the printed circuit. Cdlt 73's
