Title: DSO METEX DG scope 20 MHz - Technology of 1995-1998 ( service manual )
Post by: Kiriakos GR on April 14, 2018, 09:23:22 AM

METEX DG scope 20 MHz, this is a product designed at about 1995 and product release was at 1997~1998.
I did came across of one this sold as new ( but this is discontinued product , unsold stock ) in one Greek  electronics e-shop.
 
METEX DG scope 20 MHz, this was one product helping mostly in verification of problems when repairing color TV of 90s.
Such DSO today it is considered as good for museums.

Software option for it this is also a dead end,  windows software was available in two floppy discs.
PC Connectivity was made by RS-232 cable and port communication was possible at very slow Bawd-rate.

Bellow it is attached METEX DG scope 20 MHz service manual.

Here is a link from Russia (product pictures and PC software)  METEX DG scope 20 MHz  Windows Software (https://onedrive.live.com/?authkey=%21AEnj%5Fy8FIXeTRj4&cid=2DE4AEC71FFCB254&id=2DE4AEC71FFCB254%211486&parId=2DE4AEC71FFCB254%211481&action=locate)

Hello,

I also succeeded to obtain one of these units. My one is branded as Voltcraft DG, but this is actually 1:1 device.
Could you please provide a working link to the service manual? And is it possible to upload a photo of the logic probe PCB?
My one comes without it :( I guess that it contains just buffers and you could also even change (by hardware) the triggering logic level by tweaking its power values.....

Thank you in advance :)

Dear friend this is 23 years old product and a discontinued one.
It is unfortunate that download link this expired, ITTSB Blog does host files at external servers.
I do not own any copy of this file even for personal use.

Is Voltcraft customer support in denial to assist you?

This is good news then.
The best hint for you.
Record your own notes about voltages and signals at PCB test points now that this is still working.
