 (1) Set sub-address (00) 70.
(2) Input Signal b (horizontal period T = 35.56 µs) to pin 14 (HD3-IN).
(3) Set sub-address (02) 02.
(4) Change form 00 to 7C sub-address (03), then measure the phase change quantity (∆HP0−) of pin 16
(HD1-OUT) wave form.
(5) Change form 80 to FC sub-address (03), then measure the phase change quantity (∆HP0+) of pin 16
(HD1-OUT) wave form.
(6) When horizontal period of Signal b is T = 31.75 µs measure ∆HP1− and ∆HP1+ as well.
(7) When horizontal period of Signal b is T = 29.63 µs measure ∆HP2− and ∆HP2+ as well.
(8) When horizontal period of Signal b is T = 22.22 µs measure ∆HP3− and ∆HP3+ as well.
