good idea to attach connector pins to the test clips; this way, the pins are easily inserted into holes in 
the 8520C-36 connectors. To test a particular channel, insert the red test clip pin into the appropriate 
hole in the 8520C-36 channel connector; insert the ground test clip pin into the “P” hole in the same 
connector. In this manner, you can use a signal generator to simulate signals or perform the calibration 
tests in Section 5.5.
