After every single startup I get an error message "cal ram checksum error, re-cal instrument" After re-calibration the scope works good. If I ignore the error message and run the SELF TEST with TEST ALL option the following three lines returns with FAILED message 1.Protected Non-Volatile RAM 2.D/A converter 3.A/D converter The question is: Is it an easy to handle tipical failure (broken backup battery or something like this) or it signs a more serious problem? co zrobic: citation from the manual: "If the HP 54501 A fails any selftest perform the following: 1, recalibrate the oscilloscope 2, If that doesn't fix the problem refer to the service manual :-) Ok, I recalibrate but why after every startup? HP would probably a better source to ask for answers. I have put it also there. The more source the more info ...
