SPD3303X-E another question regarding binding posts.
<< < (9/11) > >>
daisizhou:
I am using a SPD3303D power supply, do you know how to calibrate it? There is some deviation in current in normal use, I don't know how to calibrate

Thank you tautech and  rf-loop, you both caused me to spend all afternoon getting my head around those specs, I still don't understand half of it all but have a grasp of the important parts.

Your suggestion has been invaluable and helped me to decide to go for the X-E version , the only deciding factor now is stretching the ol wallet a bit further, wallets here are being crucified at the moment.

Had my SDS1102CNL open,cant see any obvious problems like leaking or bulging caps or burnt components, a quick once over didn't reveal bad soldering, a bit of dust off and the pcb's look pretty good, probably start with the psu as it seems to be a simple tops based design and was going to forward from there but as usual, had other things to get on with.

Some of the additional cost of the X-E over X-U is componentry as X-E HW uses dual 1 GSa ADC's, each with its own 14 Mpts memory support which allows it to maintain a max sampling rate of 500 MSa/s with all channels active whereas the X-U can only manage 250 MSa/s with 4 active channels on a single ADC.

For the X-E to get 1 GSa for 2 channels, one must be on each ADC however once a 3rd channel is used sampling drops to 500 MSa/s, the same as what you would get using 2 channels on the same ADC.
It's pretty simple once you get your head around it however you'll find an X-E in another world and a lot more featured compared to your CNL.

Got that tautech, your explanation was so easy to understand.

Theres also the SDS1202X-E, its a 2 channel, seems like a nice scope, I need to think about a 2 or 4 channel as I have got by fine with just 2, well except for way back when TTL was common, back then I designed a 4 / 8 channel analyser that converted a dual trace crt into pretty handy tool but it had its limitations, there was a 16 channel version but it was clunky and bandwidth was pretty limited to a few Mhz tops IIRC.

Though going with the one you suggested, the 4 channel would give me more options and I would to have pink and green traces instead of the yellow and blue, just for a change !
