I assume these demo waveforms are stored data and not a generated waveform fed to the inputs. Therefore not a real test of the frontend.

The 'demo mode' gets activated when the XStream software can't access the acquisition board (when the interface board can't be accessed, the software won't even start).
To my knowledge, the only way to deactivate it, is via the service menu. Some have said that the demo mode might also be linked with the DEV option, but I've never seen anyone elaborate on this.

cant PM you further georgo, your inbox is full, here is the msg... (i think you need to post more to get more priviledge such as inbox space, not sure)

to be frank, i dont know what is SIL151 :-\ until you mentioned it, searching in eevblog also returns none. so i guess you have to study that outside eevblog, ie google, sorry.. looking back at your post, you've been sent chapter 3 and 4 whereas me, they only sent me chapter 5 (and lots of *lss files), but i guess chap 3 and 4 only the usual user's manual and device specification thats available in the net right? not really crucial for verification process (chapter 5) i guess. cheers.

BeckGyver:
Thanks for this input, that fits in the picture of missing/wrong voltages at the acquisition board. I will have a peak after i finish moving in the new house with a bigger bench and lab to get all tools on the table.
I will keep you in stream when I start working on this beauty again. I also got the adapters today and will be able to feed son signals as soon as I get this thing back working.
I also got an Error log of the Communication Test from the service menu:

BeckGyver,
Can you show in which section of the system menu you receive this log?
BeckGyver:
As I am currently moving to a new house I can not fire up the scope to take some pictures from the Menu, but I will do so as soon as I have a bench available.
If I am right I used "Production Access" and was able to get access to the event logs. You can export the Logs to a thumbdrive and analyze them on a real PC. In addition I noticed that some logs were overflown (in 2013) and so I exported them and cleared it afterwards.
--- Quote from: nctnico on December 08, 2019, 03:33:39 pm ---You don't need the D drive at all. And you don't need to backup anything. The factory cal data is stored on the acquisition board itself en copied onto the hard drive automatically. The missing cal data is automatically created from the data gathered at the first time the oscilloscope is started.
A self calibration can be started from the service menu. Service center access is probably enough.

I just wanted to share some news regarding possible adapters for the BMA adapter on the front. There are some adapters available from Aliexpress which cost around 10 bucks and look pretty nice. I ordered two of them:
https://de.aliexpress.com/item/32959937555.html
At the first glance they look pretty well made and I will have a test with the network analyzer at the new lab in some weeks.
I also attatched a picture of an original adapter LPA-SMA-A for reference ;-)
If someone is interested in building our own adapters please let me know. I also have some kind of galvanic isolation amplifier for low bandwidths in mind as well in the first place ( based on AMC1211x).
