Test point A-VAR (TP7) is the output of the variable DC/DC for port A. Test point B-VAR (TP6) is the output of the variable DC/DC for port B. These test points are provided for attaching an oscilloscope, multimeter, or external supply. System power (TP5) can be in the operating range of 5–20 V, any voltage lower than 20 V decreases the sourcing power capabilities. Figure 5-35 highlights these features.
