Connect a DC ammeter to the VCC pin and measure. VCC is 5V and
the ammeter is shorted for use in subsequent measurements.

Input a 2.0VP-P staircase wave to SG, and measure differential gain at TP14.
APL=10~90%
Proceed as for DG, and measure differential phase.
Input a 2.5VP-P, 1kHz sine wave to SG, connect a distortion meter to
TP14 and measure.
Measure the DC voltage difference of each switch status at TP13.
Assume VC1=2.1V, VC2=0.7V.
