Upgrading Mainboard in Lecroy DDA-3000 (aka WavePro 7300a?)
Mechatrommer:
iirc there are 1 or 2 touch drivers mentioned in this thread, or maybe i downloaded 1 driver from the net that is not working correctly, and this thread provided the one that is i believe similar to the one used by Lecroy and is working, you may want to check that. for device driver, ingowein's is more stable on multi core cpu. and make sure you try to recover the calibration data in original HDD D:\ with your tooth and nail and put it back in the new installation.
btw guess what arrived today?... https://www.ebay.com.my/itm/Lecroy-TF-USB-USB-Compliance-Test-Fixture/174049371468 the seller accepted the offer $100, took me many months to hunt and wait for the price to be accepted from sellers. who the heck design USB2 nowadays anyway? its just so i can collect SDA/DDA era legacy goodies for nostalgic moment, maybe i can use it for learning/design purpose, or maybe not :P

Hi All
I noticed that my WP7300 had some failed self test "Power On" in Service menu. I repeated it and it seems to fail every time. Where can I found any details? I'm worried a little. Everything always worked 100% fine, and works great now too. I did memory and CPU change about a year ago.
Converter:
I have tested many WP7K devices and always have this test with an error. I do not know what caused this.
Mechatrommer:
maybe we can ask lecroy what is this about?

FYI: the touchscreen works after a reboot. The "autoset" button remains MIA.
Just an FYI: it were actually a few buttons, all related to a bad diode on the button board. Replaced it, it was good after that. So, if you ever have a few misbehaving buttons: beep out the diodes.
