The Siglent SDG1000 and SDG800 thread

<< < (53/81) > >>

malekia:
I recently returned an SDG1025.
Functionally it was fine. Square wave wasn't too great at higher frequencies, but this may be common in this price range.
My main reason for sending it back was that I couldn't tolerate the display's horrible color-scheme any longer. Your mileage may vary.

Coll:
I currently own a SDG1025 I am loving it so far but I am having a bit of an issue with it. Channel 1 DC utility can give me +/-10 volts max. Channel 2 however is only giving me a max of +/-3 volts. Is this something that is supposed to happen? Or did I possibly mess up a setting somewhere?

That is one of the unfortunate limitations of the SDG1000 series  :palm: I have cursed it a couple of times already.

I kind of agree with you on the colour scheme. It's not obvious what channel you are working with, and the CH1 / CH2 being backwards doesn't help. I am one of the 10% of all males that have that red/green colour blindness gene. It's really trivial in real life, but I suspect it shows up with interfaces like this. Others seem perfectly happy  :-//

Anyone could always flash the LeCroy Wavestation firmware instead and then CH1/CH2 are in order and I think it has a much better colour scheme. Though you lose the frequency counter and I expect all the most recent bug fixes too.

IIRC the LeCroy firmware switches the CH1/CH2 purely in software, and that includes the 10v and 3v limits too. Which makes me wonder why? The individual channels hardware can do 10V just by software alone... Perhaps it's an overall power thing that is being enforced over both channels?
