6 Parameter Measurement Information

Figure 6-1 through Figure 6-3 show the various test setup configurations for the BUF802.

BUF802 Auxiliary Path Electrical Characteristics MeasurementFigure 6-3 Auxiliary Path Electrical Characteristics Measurement

Figure 6-2 shows the two inputs for BUF802 (IN and In_Aux) which control the output. The IN pin controls the output of BUF802 through the Main Path, whereas the In_Aux pin controls the output through the Auxiliary Path. Either the Main Path or the Auxiliary Path, can be used to steer the output. The electrical characteristics of the Main Path and the Auxiliary Path is specified in Section 5.7.
