R&S ZVB8 VNA

[fjullien]

Hi,

I've got a ZVB8 VNA, it shows an error message when the application starts: "Hardware detection failed!"
Does anyone has a ZVB8 and can check if the device manager shows something more than mine (see attached screenshot) ?

I was thinking I could reverse the application to see what is checked before it starts but it's not the easiest way to start fixing this device...

Franck.

I do have one, but its power supply is broken...

Hello
Nice equipment, how much does something damaged like that cost?
I have been looking for a low budget VNA for some time now.
Where do you buy these?
Best regards Jarek

 I paid sth. like €10K + VAT for it in working order, had to
re-import it from Asia to Germany maybe 8 years ago.
I found a switch mode power supply for €1K + hefty
€500 for transport; someone else seems to have
bought it.   

BTW I copied the hard disk to a small SSD, block-wise.
So at least the software should be able to be recovered.

[fjullien]

I didn't pay mine.
It came from another part of my company. During transport, it got broken.

I need to open it completely to see if I can spot something obvious.
Just opening the top and making a visual inspection shows nothing.

Hi Gérard!
If you are going to repair the power supply I can help.

Hi Franck!
Let you see the screenshot.

[fjullien]

Thank you !
So I'm missing "R&S SMBus Device" and something under "Ramdisk".
Can you please expand the Ramdisk item and get details about the device ? Also for the "R&S SMBus Device" ?

[Harry_22]

Ramdisk
            Windows RAM Disk Controller
 Device ID ROOT\RAMDISK\0000
 Hardware ID ramdisk

[fjullien]

Thanks.
No sure it'll help, I'll post here if I find something.

[Harry_22]

Seems that main problem is missing SMBus Device.
Let you start with the simple things.
-First, check all supply voltages (please see the picture). The power supply here is very reliable and the absence of one voltage is very rare. But do it anyway.
-Then check the fuses on the connection board. You access them from the bottom of the device.
-And finally I suggest removing the internal device modules one by one and checking the appearance of SMBus.

[fjullien]

Power supplies and fuses are good.
I agree, this missing SMBus Device is a problem.

I do have an SMB Controller. Not the good one.

Its Vendor/device ID suggests that it's a ICH8 SMB Controller. However, the board has an ICH2...
My guess is that this device is in reality the Altera CPLD. It might implement a PCI device.
Could you check what driver is used for your R&S SMB Device ?

[Harry_22]

Perhaps this is a different version of the controller. I checked several ZVB20 and they are identical (please see the picture).
 
I also installed Win_XP on separate 1091.2814.00 controller featured by 82801BA southbridge. It shows the same 2443 system device.
Do you know your controller number?

[Harry_22]

I disconnected all the modules including both ports. Software started but terminated different way. Without hardware detection fail window.

PS
It would be good to run your image on standalone controller.

[fjullien]

That's exactly the same chipset. I've run CPU-Z and I get the same result as what you posted.
My mother board has a different part number (1091.2908.00) but I can't see any difference (except the CPU fan).

Could you try to see what device driver the "R&S SMBus Device" uses ?

I'll try to run the software in "standalone" mode, with the bare mother board.

[Harry_22]

Could you prepare the image and send me a link.
 will run it on my MB.

[fjullien]

Ok, thanks !
Any preference/recommendation for the HDD cloning tool ?

[Gerhard_dk4xp]

I attached the ZVB hard disk to a Linux workstation and simply
used the standard command dd. (disk dump, if =input file...)

root@silver>  dd if= /dev/sdc1  of= big_file.bin
and then with the new disk  and the order of the files reversed.
That worked. In Linux/Unix a drive or partition can be used
as just a huge file. Triple check the device names. You can
easily kill your Linux filesystem by giving the wrong names.


I first used a Digitus board for the copy, that produced a broken
file system. You may be tempted to use a huge SSD as the new
disk. That may stress the limits of Win XP, esp. without the
disk size service pack.  A 256 GB Samsung SATA SSD worked instead
of the 160 GB Toshiba laptop sata that was in the ZVB. I made the
1st partition on the SSD  slightly bigger than required and left the
rest unallocated.

midnight here,
Cheers,
Gerhard

You can use portable version from here.

Thanks Gerhard and Harry.
Harry, I sent the link to my disk image in your DM.

[fjullien]

With the help of Harry, we found that the problem was a corrupted image on the hard drive.
It had nothing to do with any peripheral not being present....

I used a new image, copied my calibration settings and boom ! No problem anymore 

Thank again Harry and Gerhard.

Franck.

hello sir
I have a ZVB8 that its HDD was crashed.
I need a copy of HDD image.

[Gerhard_dk4xp]

Already answered the PM.

we repair Windows in our ZVH8 4-port, but lost calibration data.
try used calibration from ZVH8 2 port model, bus SW said that it's too incomplete(only port 1 and 2).
can anybody share factory.cal and factory.dat from any 4 ports ZVB (ZVB8 preffer) ?
thanks.

Code: [Select]

Factory calibration data:
There is an individual factory calibration data set stored on each instrument which is
used when no special calibration is performed. This calibration data set has been taken
in the factory and consists of two files factory.cal and factory.dat.
These files are stored on the removable Compact Flash memory in the directory:
C:\Documents and Settings\All Users\Aplication Data\
Rohde&Schwarz\Nwa\Data\calibration
