The current probe under test is clamped to the 6" / 15 cm length of RG-316 cable
across the "A" and "B" terminals of the output module. Physically, this arrangement is
shown below (with a Tektronix A6303 probe):
When using OUT2, the basic test arrangement is shown below:
This is very similar to the "OUT1" arrangement, except that a different output module is
used, and a higher-bandwidth oscilloscope may be required. Physically, this
arrangement is shown below (with a Tektronix P6042 probe):
