· Measurement Procedures

Consumption current

short the ammeter to use.

Voltage gain

Frequency characteristic

fc

MM1512) is V3, find fc by the following formula.

fc = 20LOG (V3/V2) dB

Differential gain

DG

to SG2, and measure differential gain at TP2.

APL = 10 ~ 90%

Differential phase

DP

The same as for DG, but measure differential phase.

Y output dynamic range

amplitude under THD 1%, at TP2.

Input an APL 50% luminance signal to SG1 and input a chroma

signal to SG2. Change the chroma signal amplitude and measure

distortion at TP2.

C output dynamic range
