(1) V_DC input : DC voltage is variable
(2) Measure the TP5 parabola amplitude V_EH (7)
when DC = 7 V.
(3) Likewise, measure the amplitude V_EH (1) when
DC = 1 V.

(1) V_DC input : DC voltage = 1 V
(2) Measure the TP5 parabola phase center voltage
V_PC (00) when set the data of subaddress [09] to
(00).
(3) Likewise, measure the voltage V_PC (07) when set
the data of subaddress [09] to (07).

(1) Connect an ammeter between TP3 and GND.
(2) Read the current.
(1) TP21 input : Same as 2 above (trigger pulse).
(2) Monitor the TP24 waveform. Measure the V_x
below.
I_AGC0 = V_x ÷ 200 (µA)
(I_AGC1)
Note: Unless otherwise specified in the bus data and SW mode column, use PRESET values
and SW-A.
