ON (1) Input sine wave of frequency F_VSM to TPA.
(2) Set picture mute to off (P-MODE: Normal1 (000)), VSM GAIN to 100 and pin 3 amplitude to 0.1 V_P-P. Monitor
pin 54.
(3) Input pulse as shown below to pin 49 and determine response times T_VM49A and T_VM49B.
(4) Likewise input pulse to pin 50 and determine response times T_VM50A and T_VM50B.
(5) Likewise input pulse to pin 51 and determine response times T_VM51A and T_VM51B.
