14:53 At high frequencies you should match the impedances. That's why the rectangular wave at 30MHz is so distorted. Notice that already at 10MHz reflections appear.
The main reason why there's distortion and a smaller amplitude at higher frequencies, is the capable bandwidth of the oscilloscope. For a 80 MHz you would need at least a 200 MHz capable oscilloscope !!!
Hello Khuong, glad I could help! I have to say, if I haven't bought my Rigol when i setup my workbench, this will propably be the next in line. Maybe a Owon also... but this one is pretty good deal for the price. Thanks for watching! 👍
Hugi, great work...a couple of questions/comments. Is the BT module included?... One thing that seems absent or lacking from some reviews is the instruments low signalevel abilities. We always see the 1V, 2V or greater outputs which doesnt speak to mV levels free of internal noise. This is important when working into the RF regions. Yes of course an external 50 ohm attenuator can be used but this doesnt help sugnal to noise ratios. Thanks again for your work. Gene
Hi, sorry this late reply, trying to catchup with all the comments. Yes, the Bluetooth module is included. I will try to see in the future if I cover better the mV output of the signal generators. Thanks for watching.
Thanks for the nice video! I am quite new to the field so please excuse if this is a stupid question. I was under the impression, that the amplitude of 3.6 V shown at 32:07 is the peak-to-peak amplitude, as on the device itself it also says 3.6 Vpp. However, the plot in the software shows a wave from -3.6 V to 3.6 V. Is this a mistake in the software-plot or am I missing something? Thanks in advance :)
Hi, I think you're right and that might be some kind of bug in the software, since even if it is really small, on the oscilloscope you have 1,8V +/- in the VPP section, second square on the bottom. But nice catch. Thanks for watching.
Hi Maria, yes it is. I think I show that in the video, but if failed to show, I can confirm that it does allow you to change the impedance. Not sure if allow you to specify different impedances, but almost sure it does too. Thanks for watching!
Can you tell me where I can order the small TTL interface to comminicate with the iPhone? My Juntek PSG9080 did not come with it and no mention of this adapter on the Juntek web site.
Здравствуйте, хотел спросить а генератор JUNTEK PSG9080 можно запрограммировать там где программируются последовательность различных сигналов во вкладке FUNC, чтобы работали SWEEP, VCO и модуляция? Если не знаете, попробуйте пожалуйста, очень нужно знать, делаю выбор. Hello, I wanted to ask if the JUNTEK PSG9080 generator can be programmed where the sequence of various signals is programmed in the FUNC tab so that SWEEP, VCO and modulation work? If you don't know, please try, I really need to know, I'm making a choice.
Hi, I will try to test what you need to know, but can you explain better what you need to have? You want to be able to program the sweep, vco and modulation? You can configure the parameters of all of these function individually, but if can explain it better what you need, I will test on my unit. Thanks for watching!
Hello! Sorry for late reply, house move and vacations. That's a good questions, in my new lab I will bring it back to the workbench and test it asap. Maybe I will do a new video with this. Thanks for watching!

Hi, I will review the video and take that as a lesson for future reviews, thanks for noticing and for watching!

Excellent review of this instrument that I just ordered. I can't wait to get it. It will be mainly used for healing purposes !
Hi, thank you for your nice comment, hope your enjoy your new FG! Thanks for watching.
Thanks for the detailed review Hugo. I was actually looking into buying this. So your review came at a perfect time.

Thanks again a new great Video Review, really appreciate your hard work doing this! Kind Regards and all the best from Austria :-)

Hi! Nice review! Is it possible to adjust output load from 50 ohms to High Impedance or High Z on PSG9080??
Hi Maria, yes it is. I think I show that in the video, but if failed to show, I can confirm that it does allow you to change the impedance. Not sure if allow you to specify different impedances, but almost sure it does too. Thanks for watching!
Isn’t that matter in circuit testing that other forms of waveforms not quite accurate in high frequency?
Hi, probably, are you referring to something I said? Thanks for watching.
Can you tell me where I can order the small TTL interface to comminicate with the iPhone? My Juntek PSG9080 did not come with it and no mention of this adapter on the Juntek web site.
Hello, I didn't find it on aliexpress, I'm gonna ask them if they have it for sale. Thanks for watching!
The TTL interface is still not available anywhere. Sad@@TechCornerTV

@@TechCornerTV Да, вы правильно поняли, я хочу последовательно запрограммировать sweep, vco and modulation.
Can this do really as low as 1nHz?
