Here's a link to a thread on this from the 9-5 BB. Anders has posted lots of useful information on this in the past, and he made up a nice photo of a normal looking pump signal next to a bad one with dropouts. The pump should be operating at a constant frequency also. Bobc has the trace picture in his gallery and if you follow the threads from below, there is lots of useful information. It's a great quick and easy diagnostic that might catch a bad pump.
