Notes)
1) Linearity testing
For A channel, set input bias to ABCN – 0.2V first, and then set it to ABCN and ABCN + 0.2V. Then input a
sine wave of 100kHz and 100mVp-p, and compare the three output amplitudes. For B channel and C
channel, set input bias to ABBL + 0.45V first, and then set it to ABBL + 0.25V and ABBL + 0.05V. Then
input a sine wave of 100kHz and 100mVp-p, and compare the three output amplitudes. The maximum
output amplitude for the respective A, B and C channels is taken as Sout max and the minimum output
amplitude as Sout min. The linearity of the respective channels is defined as:
Lin. = Sout max – Sout min
×
200 [%]
Sout max + Sout min
2) Calculation of insertion gain difference
As the maximum insertion gain among A, B and C channels is taken as Gmax and the minimum as Gmin,
the insertion gain difference between channels

3) Calculation of linearity difference
Define B channel linearity as L
