Agilent 54622D / Replacing backup battery

Hi,

I am about to replace the 3V lithium battery of my Mixed Signal Oscilloscope Agilent 54622D.
The oscilloscope is 7 years old and the voltage of the original battery is now down to 2.97V.
Until now I have not seen any error message about this backup battery but I want to be
ready to replace it.

The lithium battery CR2354 is soldered on the system board.
Anything I should know before I replace the battery?

After replacing the battery, setting the time (RTC) and
then performing a self-calibration "User Cal" will be enough?

Any information is greatly appreciated. Thank you in advance.

Best regards,

Paolo

Yes, the new battery is soldered in place. There are no special precautions except standard procedures. Use the least amount of heat needed to de-solder the old part and solder in the new part. I also suggest you use a ground antistatic mat and wrist strap if one is available to you. Some scopes did not use a solder-in part, the battery just snapped into a fixture. But on your scope you have to solder the three prongs to the board. You are also correct in setting the time and date plus the user self cal. You may also loose your trace and setup files. You could save them to your PC using BenchLink scope, if you have that program. BenchLink scope is not available from Agilent any longer. There are no other cals or files that you need to save or re-create on the scope.

Why not? I sure wish Agilent would just post this stuff to a website (without support) if they decide to kill the product. A lot of us live on slightly older test equipment and can't afford to buy the latest and greatest. (I can barely get my department to do that at work and they have a real budget).

It would be great to have all this old stuff simply available for use if Agilent decides to stop selling it. It might actually generate some sales if someone gets stuck with the older free stuff and discover there is a newer, better (paid for) solution.

Intuilink (free) which replaced Benchlink ( ridiculously overpriced for what it did) supports this scope.

(Quick update after two years).

Until now it was not necessary to replace the lithium battery because its voltage is still around 3V.
(This is the original lithium battery installed during manufacturing in November 2000).

The oscilloscope is powered on for about eight hours a day.
(The rest of the time the lithium battery must supply current).

After all these years the oscilloscope still works perfectly.

Thank you Agilent!

Best regards,

Paolo
