Having installed it there were one or two obvious problems. The software recognised the DSA815 with EMI but every time it was asked to perform a sweep at say 9kHz bandwidth it would say the test instrument was not capable and immediately switch the EMI function off. This is at present waiting a response from RIGOL USA help centre. The help functions, like Windows, seem to have all the answers for all the questions you never need to ask but the ones you do, have no reference whatsoever. A good example is how to display two traces for comparison. Eventually discovered in set reference pull down! Another annoying thing is the frequency axis display being in exponential figures when everywhere else the data is entered in normal decade Hz. When I get the EMI function working it should be ok but it needs a lot of refining to bring it up to a satisfactory standard in my opinion. Waiting in anticipation for the next revision!!
