3-CHANNEL VIDEO AMPLIFICATION WITH OSD BLANKING
VB2 Brightness control characteristics (typical)
∆VB2 Brightness control relative characteristics (typical)
1. Measuring conditions are as given in Supplementary Table.
2. Measure the output at T.P25 (30 or 35) with a voltmeter.
The measured value is called VOR7' (VOG7' or VOB7'), and is
treated as VB2.
3. To obtain brightness control relative characteristics (∆VB2),
calculate the difference in the output between the channels,
using VOR7', VOG7', and VOB7'.
∆VB2 =VOR7'-VOG7'
=VOG7'-VOB7'
=VOB7'-VOR7'
[mV]
VB3 Brightness control characteristics (minimum)
∆VB3 Brightness control relative characteristics (minimum)
1. Measuring conditions are as given in Supplementary Table.
2. Measure the output at T.P25 (30 or 35) with a voltmeter.
The measured value is called VOR7" (VOG7" or VOB7"), and is
treated as VB2.
3. To obtain brightness control relative characteristics (∆VB3),
calculate the difference in the output between the channels,
using VOR7", VOG7" and VOB7".
∆VB3 =VOR7''-VOG7''
=VOG7''-VOB7''
=VOB7''-VOR7''

FC2 Frequency characteristics2 (f=50MHz; maximum)
∆FC2' Frequency relative characteristics2
(f=130MHz; maximum)
Measuring conditions and procedure are the same as described in
FC1, ∆FC1, FC1', ∆FC1', except that CONTRAST (V17) is turned
down to 1.5V.
C.T.1 Crosstalk1 (f=50MHz)
C.T.1' Crosstalk1 (f=130MHz)
1. Measuring conditions are as given in Supplementary Table.
2. Input SG2 (or SG3) to pin 13 (R-ch) only, and then measure the
waveform amplitude output at T.P25 (30 or 35). The measured
value is called VOR, VOG and or VOB respectively.
3. Crosstalk C.T. 1 is calculated by the equation below:
VOG or VOB
C.T.1 =20LOG

C.T.2 Crosstalk2 (f=50MHz)
C.T.2' Crosstalk2 (f=130MHz)
1. Change the input pin from pin 13 (R-ch) to pin 8 (G-ch), and
measure the output in the same way as in C.T.1, C.T.1'.
2. Crosstalk C.T. 2 is calculated by the equation below:
VOR or VOB
C.T.2 =20LOG
(C.T.2')
VOG

FC1 Frequency characteristics1 (f=50MHz; maximum)
∆FC1 Frequency relative characteristics1

FC1' Frequency characteristics1 (f=130MHz; maximum)
∆FC1' Frequency relative characteristics1
(f=130MHz; maximum)
1. Measuring conditions are as given in Supplementary Table.
2. SG1⋅SG2 and SG3 are input. The amplitude of the waveform
output at T.P25 (30 or 35) is measured.
3. Supposing that the measured value is treated as amplitude VOR1
(VOG1 or VOB1) when SG1 is input, as VOR8 (VOG8 or VOB8) when
SG2 is input, or as VOR9 (VOG9 or VOB9) when SG3 is input,
frequency characteristics FC1 and FC1' are calculated as follows:
C.T.3 Crosstalk3 (f=50MHz)
C.T.3' Crosstalk3 (f=130MHz)
1. Change the input pin from pin 13 (R-ch) to pin 3 (B-ch), and
measure the output in the same way as in C.T.1, C.T.1'.
2. Crosstalk C.T. 3 is calculated by the equation below:
VOR or VOG
C.T.3 =20LOG
(C.T.3')
VOB

4. Frequency relative band widths ∆FC1 and ∆FC1' are equal to the
difference in FC1 and FC1', respectively, between the channels.
