Opinion about UTG 9005 C :: Function generator 5 MHz
(1/1)
Jasonbit:
Hello folks,
I am reading about function generator here on the forum and I didn't find reviews or topics about UTG 9005 C (https://www.reichelt.com/pt/en/function-generator-5-mhz-utg-9005-c-p102158.html?&trstct=pol_0).
Also I search about this equipment on channel David (EEVblog channel youtube) but I didn't any information about this equipment. Therefore I decided ask yourself what you think of this model and if there are other equipment in this range. Remember, I am a newbie user and enthusiastic electronic guy. For now I don't need anything very professional anymore.
Thanks

I like the offer of wave types that have! Also I like the signal range it offers (0.5Hz to 5MHz). I never use function generator which "frequency counter" but this is will good for my learning.

I like the values of Amplitude. For example, I can use this equipment to test and validate a circuit as signal rectifier (to developer a power supply), thus replacing the use of the transformer (in the testing phase), right?
I don't know evaluate characteristics such as "Accuracy / resolution" or "Loss" or "distortion, sine wave" ... so I don't have much to say.

As I don't known what the frequency counter is for I will try to guess what it is for. This parameter it is important to know what and which voltage I can put on frequency counter. For example, I can put the output signal the traditional circuit 555 astable and counter the cycle of frequency, for example, 1KHz, right?

It seems like an older device, before DDS function generators became popular and cheap. Basically before you needed quite a bit of analog wizardry to get it right but with cheap DDS you pretty much just need an output amplifier and a micro to drive it.
I'd recommend starting with one of those cheap chinese DDS generators, you can get one for $50 bucks or less:

And overall will have better parameters, just in much cheaper box, and if you ever "grow out" out of it, you'd then know what exactly you miss.
There are even more fancier ones:
