procedure would be complete.
To generate any other signal type, three steps are required. First, move the plug in JP2 to the DC jumper
(e.g., J4 DC). Second, select a signal type from the following table and note the corresponding switch
position (e.g., 10 MPPS = position 1). Finally, using a small flat-head screwdriver, turn the rotary switch
(e.g., S4) to the appropriate switch position (e.g., 1). In this example, the J4 output would be set to
