Hi Gerhard !
I have exactly the same error message. I checked the user manual (page 8-1
of my edition), and they mention that it could be the lithium battery on the
CPU board. Inside mine, the model of the battery is Renata 1000-0B, (CR2477N
Lithium, 3 V, 950 mAh, inside an horizontal orange box 30x30x10 mm) and it's
socketed.
It seems not too difficult to find: http://www.renata.fr/modulesDoc.php, but
I am unable to find reseller in Europe, and there is restriction of export
to UE from the USA... 8-{
There is still a possibility with Farnell, but their site is offline for
maintenance right now.
They said that that's a CR2477N battery inside the package. That one is a
lot easier to find, but I will have to check if I can tear apart the box and
replace only the cell... There is a big warning "Do not open" ...
I will let you know
Best regards,
Jean-Louis

Hello,
By any chance, would anybody have a service manual for a spectrum
analyzer model SNA23 (same as BN2101/23) from Wandel & Goltermann.
Otherwise, a service manual for another model in this serie
(SNA-20/-23/-30/-33) would be also helpful.
Same problem here, with a SNA-33. Mine thinks that its disc controller is
defunct. Maybe I still
can get service for it (called them last year), might be only the battery
for the CMOS ram disk...
Eningen is not far from here, perhaps a 40 min. drive. Currently I only do
software and digital
stuff and cannot really justify the expense, but the SNA-33 is still a top
notch SA and would
deserve repair & calibration.
