• While the User Operation screen is displayed, press the ESC then DISP keys, then the DIG/ANA
key twice, in that order.
• While subscreen 1 of the first screen is displayed, press the DIG/ANA key.

(3) Simple Error Rate Measurement (Subscreen 2)
[Measurement procedures]
1
Display subscreen 2.
2
Load the Test disc (GGV1025).
3
Judge the results of the error rate measurement by
referring to Table 1 on page 89.
[Tips]
During VR mode playback, the average value of the past 10 VOBUs is displayed. During DVD-Video or Video mode
playback, the average value of the past 256 sectors is displayed.
During VR mode playback, the speed ratio of the drive (/: normal, no indication: double speed) is also displayed.
Subscreen 2
1) AGC voltage (AGC Volt)
The gain controlled by the tuner is monitored to infer the input electric field intensity.
(The accuracy of inference differs depending on the product.)
Field Intensity

(Clear image)
Less intense field area
(Noise may be generated.)
Weak field area
(Much noise. EPG/VPS/PDC sometimes cannot be
obtained.)
Very weak field area
(Image damaged. EPG/VPS/PDC cannot be obtained.)

Tips:
For good reception, the field intensity must be 50 dB

or more (AGC Volt 4400 mV or less).
For accurate measurement, use a field intensity meter.
