ARB Generator Shoot Out Uni T Signal Generators a Closer Look

[@versace885]

HI EDDIE, I really love your videos. I always learn something new. Thank you.👏💯

[@KissAnalog]

So nice of you! I appreciate you!

[@garthhowe297]

I really enjoyed this video. I learned about functionality I didn't even know existed. The 4000 series is of interest to me. The 9500 model is awesome, just way too expensive for a humble hobbyist. :)

[@KissAnalog]

I totally agree with you. I learned a lot doing this video. I love the 9000 series but the 4000 series or even the 2000 series is probably what I want/need.

[@davearmstrong1932]

I haven't watched the whole video yet, but what I don't understand is the megahertz that is listed on front of the generator .Many expensive ones are around 30 MHz . And Juntek 9080 is 80 MHz. Some are 10 MHz. Don't have much money, and I don't understand what I might need, I won't get beyond vintage AM and FM radios and maybe a vintage TV or two.

[@garthhowe297]

The MHz number prominently displayed on them, is the highest frequency Sine wave they can generate. Looking at the Uni-T UTG3082A spec sheet... 80 Mhz Sine, 30 Mhz Square/Pulse, 2 MHz Ramp, etcetera. So if the frequency of waveforms other than a Sine wave are important to you, you need to read the datasheet carefully. I'm not sure what your needs for radios and vintage tv might be... although I would like to know myself.

@garthhowe297 Great response;)

Hi eddie,I drop you a mail, hope you could check that out. Btw, thats very awesome piece of tech you got there. Man oh man, you have it all. Very nice content. God bless you.. keep it up.

[@KissAnalog]

Thanks so much!

Do these generators have a carrier tone to setup IF circuits on radios?

[@KissAnalog]

Great question! Yes, I think the carrier tone would be either the continous wave shape or the modulation - right?

Can you a shootout against Rigol Siglant HP keysight? I would love see that if you can nice lab great video thanks for doing this.

[@KissAnalog]

Thanks for asking! Funny thing is - Siglent initially said that they would look into it - but now won't answer my email. Keysight actually reached out to me - but now wont answer my email. My channel is too small;( I got this Rigol for exactly that video that you are requesting... Thanks Rigol!!

[@davearmstrong1932]

The 60 MHz Uni T generator was the first one to catch my eye but I still am not sure of what I need.

[@KissAnalog]

Thanks for this honest response! The first thing to understand is what frequency it is that you need. Many of us don't need these high frequencies. The other options and resolutions might be more important to some of us.

[@davearmstrong1932]

Intermediate frequency for AM is 455 KHz give or take depending on the radio. FM intermediate frequency is 10.7 MHz. The FM band starts at around 88 MHz. to 108 MHz All of these new generation generators seem to have AM and FM modulation. So how does the advertised MHz relate to what I need ? I don't think I will need or use nothing more then the sine wave.

[@KissAnalog]

Great question! The generator with 500 MHz is not low cost but would do what you need. I'm sure we can find a generator that better suits what you need without all the cool features that these have. I'll look into this and come back with an answer. This is a great use case that many others would be interested in.

[@davearmstrong1932]

I have been doing a lot of googling for a new simple RF generator that might work. I found one old school one with very bad reviews. I have been on eBay and all I saw was some very old antiques that might or might not work. I guess I could get one of those old Heathkits and put it on my antique test equipment shelf along side of my other old test stuff but I would like something new
