Ok, I solved the problem, I'm just stupid. To give the supply voltage in the safety, at the instrument under test, I use a 230/230 isolation transformer and a variac with which the straight edge voltage, starting from a hundred volts, and if there are no problems the increased up to the operating voltage.
This caused the flickering image, I connected the device directly to the supply network, and now the picture is still beautiful and everything ok.

Re: Problem with Canberra Series 30
Nice to hear, congrats.
I guess your next steps is to test the ADC in PHA mode and see if the front-end is OK.
Do you have a scintillator/photomultiplier with a HV supply handy?

Re: Problem with Canberra Series 30
Very nice indeed! You seem to have a very nice lab.
Please post your test result once everything is working well.
You could use the K40 1.46MeV line from a box of salt substitute from the grocery store.

Tank you, no problem, I've many sample source for test. This isn't my first MCA
I hope the weekend to do some testing and then post the results.

Hi, I did a little test of the instrument, it seems okay.
I put the picture of a pair of spectrum.
