Conditions of setting to measure the electric characteristics

Following settings must be made before measurement of electric characteristics.

Setting 1. System reset

Turn ON SW58 and start V58 from GND in order to perform system reset for MOS block.

(See fig. 1-1.)

The default value is set for the serial bus.

Setting 2. Horizontal AFC adjustment

Enter SIG5 (VL = 0mV) to (A) and adjust VCOADJ so that the width of WL and

WH becomes equal in the TP9 output waveform. (See fig. 1-2.)

(Note) In order to measure the 2MHz or more band for measurement items, such as the Y-system frequency

characteristics or sharpness characteristics, it is necessary to pass through the sample hold circuit

via serial bus.
