VB1 Brightness Control Characteristics1 Measure the DC voltage at OUT (29, 32, 35) with a voltmeter. The measured value is called VOUT (29, 32, 35), and is treated as VB1. ∆V B1 Brightness Control Relative Characteristics1 Relative characteristics ∆VB1 is calculated by the difference in the output between the channels. ∆V B1 = VOUT (29) − VOUT (32), VOUT (32) − VOUT (35), VOUT (35) − VOUT (29) VB2 Brightness Control Characteristics2 Measuring condition and procedure are the same as described in VB1. ∆V B2 Brightness Control Relative Characteristics2 Measuring condition and procedure are the same as described in ∆VB1. VB3 Brightness Control Characteristics3 Measuring condition and procedure are the same as described in VB1. ∆V B3 Brightness Control Relative Characteristics3 Measuring condition and procedure are the same as described in ∆VB1. FC1 Frequency Characteristics1 (f = 50 MHz) First, SG3 to 1 MHz is as input signal. Input a resister that is about 2 k Ω to offer the voltage at input pins (2, 6, 11) in order that the bottom of input signal is 2.5 V. Control the main contrast in order that the amplitude of sine wave output is 4.0 VP-P. Control the brightness in order that the bottom of sine wave output is 2.0 VP-P. By the same way, measure the output amplitude when SG3 to 50 MHz is as input signal. The measured value is called VOUT (29, 32, 35). Frequency characteristics FC1 (29, 32, 35) is calculated by the equation below: FC1 = 20log (dB) Output amplitude when inputted SG3 (1 MHz): 4 VP-P VOUT VP-P ∆F C1 Frequency Relative Characteristics1 (f = 50 MHz) Relative characteristics ∆FC1 is calculated by the difference in the output between the channels. FC1' Frequency Characteristics1 (f = 200 MHz) Measuring condition and procedure are the same as described in table, expect SG3 to 200 MHz. ∆F C1' Frequency Relative Characteristics1 (f = 200 MHz) Relative characteristics ∆FC1' is calculated by the difference in the output between the channels. |
