RDTech, if there is no sync signal out to the scope, how does one sync the scope to the generator for the sweep function?

Thanks

sorry, friend
there is no way to do this , sorry

I saw it , it is on the way,, it arrived at your country

I've found the mains leakage to give 312V p-p (here in the UK), screenshot attached.

I then tried testing a whole bunch of 5V USB power supplies I had, and found they all (except one, but rated only 1.2A) leaked mains voltage pretty badly.

So I'll be making a little linear 5V supply for it.

I'm not getting much luck at getting a clean signal at low amplitudes (50mV).

Apart from that, a great bit of kit.

I have put it through some tests on a Siglent SDS 2204X 200Mhz DSO and it performs rather well. The two exceptions are a)  the power pack leaks 78 V AC measured from mains earth to the DC ground of the power pack. Leakage current is 14µA. Not life threatening and can be fixed by replacing it with a transformer based PS.

Hi friend
thank you very much for your message
could you make a video to show the problem to let me help you ?

I posted a screen capture of the 312V p-p mains leakage to the Ground pin of the PSU that came with the JDS6600 in the last post.

The images for problems at low signal levels is given in the two attached photographs.

The signal generated by the JDS6600 is set at 30mV, 1kHz

One picture is a screen capture of the scope itself. One picture is of the JDS6600 showing the settings.

Kind regards,
Trys
