Auto call completed. Specan and Sig Genny doing well.
EDIT just checked the original purchase date February 11, 2003. Original battery guaranteed for five years...replaced today fifteen years later
Just found this valuable thread, thanks to HighVoltage and IconicPCB on sharing the process of replacing the internal RAM backup battery.
Just scored few days ago an used SML03, and so far from the preliminary status screens looks it should be fine, am I right ? (Photo attached below) Also briefly tested it on my scope, the signal looks pretty good up to near my scope limit (analog 400MHz).
Questions for IconicPCB :
1. Just want to be sure, so by replacing the button cell battery as you did, popping out the old one, then static RAM will be cut off from power and loose of it's content
, then install the new one, and do the internal calibration on ALL items as photo below, then I'm done ?
Reason I ask this is, as I'm just an enthusiast, loosing the cal and sending it to calibration service is out of question, as it might be far more expensive than my purchase price.
Cal screen on "ALL" items :
Also did you get similar error message (highlighted) below right after you replaced the battery ? This quote is from the instruction document for upgrading the firmware to 2.51.15.
2. Did anyone upgrade the firmware to the latest 2.51.15 downloaded from the R&S ? Any notes & precautions maybe ? As mine is still on version 2.50.6, dated back Feb 23 2006. (attached status screen below)
Few shots of the diagnostic results and the unit, came without the rear blue feet and also without the 4 bottom feet as it was installed in a tightly cramped 19" rack full of equipments. Put 6 neoprene pads at the bottom as emergency feet while searching for better alternative, any one got spare R&S SML feet ?
