First proper scope arrives today :)

Started off with a soundcard scope in 2007, then a £25 USB one in 2010, then a £50 USB one last year and today i'm getting a Rigol DSO1054Z 50MHz, can't wait :)
I've watched 'how to not blow up your scope', are there any things i should do first before using it?
I'm in UK, i've read that each probe should be calibrated with each BNC input, is that right, 16 calibrations for a 4-channel?


Thanks, Gary.

I don't think there is really anything else to do once you get it than compensate the probes. (other than maybe hack it for 100MHz..)

You want to compensate the probe on the channel you use the probe on. I'm not sure how big of an effect it really is if you use the same probe on a different channel, but it is easy to keep track of since the probes are colour coded.

Thanks Jack, will definitely be doing the 100MHz hack, i've read up on it here, including the microsecond problem.

i'm predicting few months or just weeks from now, you will get the real real scope, something like 5-6GHz 20GSps scope ;) the "Moving Forward to the Future, Breaking GHz limit" slogan for hobbiests ;D

yes and no. yes if you keep swapping probes between channels, in this case not 16 actually, it depends on how much you swap them, it can be 100... with 100 times of changing probes. and no, if you stick one probe to one channel, so 4X compensation only once in a lifetime.

i think you are referring to higher end scope, like the GHz scope, because it can recognize different probe's ID. and each probe has memory to store calibration for each channel it connected to. for Rigol probe nada, its just a passive probe.

rstofer:
Read the manual, particularly page 15-7 where it talks about the scope self-calibration.  This is done with probes removed.

There is no calibration possible on the probes.  All you can do is compensate them - page 1-8

The other references to 'calibration' in the manual refer to the digital inputs and you don't have them.

It makes sense to run the self-calibration after you do the upgrade.  Whatever you have read, "DSER" is the only valid option string if you want all the features that actually work.

ETA:  This is NOT a menu choice, you just have to go on faith.

After the self-calibration and probe compensation, you are good to go.

Remember, you are working with a 3% kind of machine - page 18-3.
