Note31) First, SG3 to 1MHz is as input signal. Input a resister that is about 2K to offer the voltage at input
pins(6,9,11) in order that the bottom of input signal is 2.5V.
Control the main contrast in order that the amplitude of sine wave output is 4.0Vp-p.
Control the brightness in order that the bottom of sine wave output is 2.0Vp-p.
By the same way, measure the output amplitude when SG3 to 50MHz is as input signal.
The measured value is called VOUT(
24,28,31
).
Frequency characteristics FC1(
24,28,31
) is calculated by the equation below:
Note32) Relative characteristics
FC1 is calculated by the difference in the output between the channels.
Note33) Measuring condition and procedure are the same as described in Note31,expect SG3 to 200MHz.
Note34) Relative characteristics
FC1' is calculated by the difference in the output between the channels.
Note35) SG3 to 1MHz is as input signal. Control the main contrast in order that the amplitude of sine wave
output is 1.0Vp-p.
By the same way, measure the output amplitude when SG3 to200MHz is as input signal.
The measured value is called VOUT(
24,28,31
).
Frequency characteristics FC2(
24,28,31
) is calculated by the equation below:
Note36) Relative characteristics
FC2 is calculated by the difference in the output between the channels.
Note37) Input SG3 (50MHz) to pin2 only, and then measure the waveform amplitude output at
OUT(
24,28,31
).The measured value is called VOUT(
24,28,31
).
Crosstalk CT1 is calculated by the equation below:
VOUT(24,28)
CT1=20 LOG
VOUT(31)
Note38) Measuring condition and procedure are the same as described in Note37,expect SG3 to 200MHz.
Note39) Input SG3 (50MHz) to pin6 only, and then measure the waveform amplitude output at
OUT(
24,28,31
).The measured value is called VOUT(
24,28,31
).
Crosstalk CT2 is calculated by the equation below:
VOUT(24,31)
CT2=20 LOG
VOUT(28)
Note40) Measuring condition and procedure are the same as described in Note39,expect SG3 to 200MHz.
Note41) Input SG3 (50MHz) to pin11 only, and then measure the waveform amplitude output at
OUT(
24,28,31
).The measured value is called VOUT(
24,28,31
).
Crosstalk CT2 is calculated by the equation below:
Note42) Measuring condition and procedure are the same as described in Note41,expect SG3 to 200MHz.
