VTEXTB
VTEXTW
Input SIG5 (VL = 0 mV) to (A) and SIG6 (variable VL) to (C).
Let VEXTB be the voltage at which the T41, T44, and T46
outputs reach the black level when the amplitude (VL) is
raised starting at 0 V. Then, let VTEXTW be the voltage at
which the outputs reach the white level as the amplitude is
increased further.

TDEXTH
TDEXTL
Input SIG5 (VL = 0 mV) to (A) and SIG6 (VL = 3 V) to (C).
Measure TDEXTH, the delay in the T41, T44, and T46
output rise, and TDEXTL, the delay in the output fall time.

blanking level difference
EXTBK
Input SIG5 (VL = 0 mV) to (A) and SIG6 (VL = 1.7 V) to (C)
and measure the difference from the T41, T44, and T46
black levels.
External RGB input to output
white level difference
EXTWT
Input SIG5 (VL = 0 mV) to (A) and SIG6 (VL = 2.7 V) to (C)
and measure the difference from the T41, T44, and T46
black levels.
