OBLK OSD BLK Characteristics
Measuring the amplitude output at OUT (2, 5, 9). The measured value is called OBLK.
ΔOBLK OSD BLK Relative Characteristics
Relative OSD BLK characteristics ΔOBLK is calculated by the equation below:
VthOSD OSD Input Threshold Voltage
Reduce the SG5 input level gradually, monitoring output. Measure the SG5 level when the output reaches 0 V. The
measured value is called VthOSD.
VthBLK OSD BLK Input Threshold Voltage
Confirm that output signal is being blanked by the SG5 at the time.
Monitoring to output signal, decreasing the level of SG5. Measure the top level of SG6 when the blanking period is
disappeared. The measured value is called VthBLK.
I
Supply 5 V to V19, and then measure input current into pin 19.
I
Supply 0 V to V19, and then measure input current into pin 19.
I
Supply 5 V to V20, and then measure input current into pin 20.
I
Supply 0 V to V20, and then measure input current into pin 20.
I
Supply 5 V to V (24, 25, 26) and then measure input current into pin (24, 25, 26)
I
Supply 0 V to V (24, 25, 26) and then measure input current into pin (24, 25, 26)
I
Supply 5 V to V27, and then measure input current into pin 27.
I
Supply 0 V to V27, and then measure input current into pin 27.
