Hi, I have at work one 8590B that has suffer of boring problem of backup battery dead.

I have replaced the battery (both lithium and supercap) and I tryed to recalibrate the instrument.

When I performed early attempts, the 8590 says that not found the calibration signal.

In effect it was displayed with a considerable offset.

I have tryed a -37Hz procedure, and with this both amplitude and frequency calibration starts, but the process end with span sens fail.

The display obtained is strange, I show it in attachment.

Naturally, these errors don't manifestate prior to battery fail.

I hope that someone can help me to restore this analyzer, thanks in advance.
