The satellite boxes for the quad test stand have jumpers to select different modes of operation. When using the test stand to do noise tests on AOSEMs it may be convenient to change the jumpers on channels that normally look at BOSEMs, so as to be able to test as large a batch as possible. For future reference the attached photo shows the correct settings for BOSEMs. For AOSEMs (as on the quad PEM stage) move the jumpers to the opposite positions.
