Setting Conditions for Measuring Electrical Characteristics
When measuring the electrical characteristics, the TG (timing generator) block must be initialized by performing
Settings 1 and 2 below.
Setting 1. System reset
After turning on the power, set SW1 to ON and start up V1 from GND in order to activate the TG
block system reset. (See Fig. 1-1.)
Setting 2. Horizontal AFC adjustment
Input SIG5 (VL = 0mV) to (A) and adjust serial bus register PLL ADJ so that WL and WH of the
TP12 output waveform are the same. (See Fig. 1-2.)
