Hi Holger, Measure the voltage at the output terminal of U3, the +5V regulator that supplies U1's V_DD voltage. If that is also 4.833 V DC, then all is OK.
Due to component variations, one can expect to measure DC voltages within 10% of the nominal table values. Your reading, depending on which pin you measured, is within that tolerance. The DC voltage table in the KPA100 manual also indicates that voltages are those measured when the nominal +12V DC supply is actually set to +14.1 V. This won't make a difference for the U3 output, but it may affect other readings if your supply is set for +12V. 73, Mike, K8CN ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
