Notes)

1. Linearity testing

For A channel and B channel, set input bias E1 to ABCN + 0.2 [V] first, and then set it to ABCN [V] and ABCN

– 0.2 [V]. Then input a sine wave of 100kHz and 100mVp-p, and compare the three output amplitudes.

For C channel and D channel, set input bias E1 to ABBL – 0.4 [V] first, and then set it to ABBL – 0.2 [V] and

ABBL [V]. 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, C and D 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

Sout max + Sout min

× 200 [%]

2. Calculation of insertion gain difference

As the max. insertion gain among A, B, C and D channels' is taken as Gmax and the min. as Gmin., the

insertion gain difference between channels becomes:

( ) Gmax – Gmin

∆G = ABS (1 – 10 20 ) × 100 [%]

3. Calculation of linearity difference

Define A channel linearity as LA, and B channel linearity as LB. We obtain the difference ∆LAB as follows.

∆LAB =  LA – LB  [%]

Similarly we obtain the linearity difference ∆LCD of C channel and D channel as follows.

∆LCD =  LC – LD  [%]

4. Crosstalk calculation

We take CRTa as: A channel crosstalk value only during B channel input

CRTb as: B channel crosstalk value only during A channel input

CRTc as: C channel crosstalk value only during D channel input

CRTd as: D channel crosstalk value only during C channel input

The crosstalk value of respective channels becomes:
