Hello,
Salut !
I am new on this forum. I have read a lot of posts since few months, but i have never took time to post or introduce myself. It is time to change this.
I am 31 years old, living on south of France. I have worked 7 years in an electronic board fabrication factory as technician and finally production manager. 2 years ago i have done professional re-conversion as building craftsman, to work in family business.
Electronic is now a passion rather than a job. I take only pleasure and no more constraints.
Same for me. Worked as an electronic engineer for 10 years (including a bit in France, I studied there) and now doing something else.
But in the end I find it difficult to make my choice among all these possibilities. I would like to have the "best bang for my buck", and equipment that I could keep for some time. I have some experience (from my last job) with some Agilent pieces but not with Rigol, Siglent. If it is advisable i can wait for some bargain on Ebay.
I have found that it is more and more difficult these days to find good bargains on used equipment.
I wrote an extensive thread about this and people seem to mostly agree.
Unless you are willing to spend a BUNCH of time scouting eBay, LeBonCoin, and other sites hoping for a deal, you will save a lot of hair by purchasing new.
Here is where i am now :
For the general purpose PSU, from here i can buy Those :
-Used Agilent E3631a for around 350€
-New GW Instek GPE-4323 for 350€
-New Rigol DP832 for 490€
-New Siglent SPD3303X-E for 440€
It's a bit expensive but bang for the buck seems to be great.
For a more powerful PSU for 24V motors, i have yet no idea.
The PSU that has been listed above, Kikusui, is in the united states. You are in France. It does not make sense to purchase a 23kg power supply overseas in my opinion, if you can avoid it. But it is true that if you are looking for a PSU for motors, you might not have a lot of options.
For the bench DMM, i have think about Agilent 34401A. From here, i can find one for 200-250€.
Very good choice.
For the hand DMM, i have forgot what Fluke i used on my last job and don't know a good one.
I personally have an old Velleman entry level DMM and it is far enough. I have been using it for more than 15 years. If you have a good bench DMM, I do not believe you need to invest in an exceptional hand DMM. Just get a basic one.
The Brymen are good, UNI-T has some good ones like the UT61E. I am really not sure why people invest in super expensive hand DMM.
For the oscilloscope, i have use some basic Tektronix at work. But from what I understand there is a big difference between olds DSOs and new ones. So I think about Rigol ds1054z (390€ here) and Siglent sds1104x-e (500€ here).
The Siglent is a bit better, but for what you want to do, it seems like the Rigol will be plenty enough. It is a very popular model. Make sure you know about the fact that it can be "enhanced"
search on the forum
For functions generator, i have found an offer for an Agilent 33220A for 150€. I don't know if it is a good bang for the buck, i guess it is.
Are you SURE you need a function generator ? I see a bunch of people buying one and I have no idea what they do with it.
What do you want to do with it ?
All of these products seem to be good value for money, but are at the high end of my budget for each item.
There is a saying, "poor people pay twice"
Lab equipment is very long lived and will service you for years, possibly decades.
It is very important to make sure you purchase the right equipment. Not too expensive but also not too cheap. If you are too cheap, you will have to repurchase in a few years, paying twice.
You can always resell to offset some of the cost but it is a hassle
Here is. As you can read, I am a little lost among all these possibilities and I lack knowledge about new products.
Can you enlighten me please ?
Thanks a lot,
Have a good day.
