TEST METHOD
(1) No TP21 input
(2) V_DC input : DC voltage is variable (0 to 6 V)
(3) Measure the TP9 voltage change in relation to the
change in the TP7 voltage and calculate the
following G_V.

Measure V_L9 as above.
(1) Set V_DC to 6V as above.
(2) Connect an ammeter between TP9 and GND and
measure the current.
(1) TP21 inpu : Same as 2 above (trigger pulse).
(2) Measure the TP7 vertical saw wave amplitude.
(1) TP21 input : Same as 2 above (trigger pulse).
(2) Measure the TP7 amplitude V_P7 (00) when set
the subaddress [00] to (00).
(3) Next, measure the TP7 amplitude V_P7 (7F) when
set the subaddress [00] to (7F).
