TEST CONDITIONS (DEF VCC = 9 V, Ta = 25 ± 3°C, BUS DATA = POWER-ON RESET)
SW MODE
NOTE
ITEM
SW28
MEASUREMENT METHOD
G18
E-W Amp Maximum Output
Current
A
Connect an ammeter between #23 and GND.
Measure the current.
G19 AGC Operating Current 1
A
G20 AGC Operating Current 2
A
Measure the TP26 waveform peak value. (VAGC0)
Set the subaddress (06) D0 to (1) and repeat the measurement. (VAGC1)
IAGC0 = VX ÷ 200 (A)
(IAGC1)
G21 Vertical Guard Voltage
A
Set #25 to open. Connect an external power supply to #25. Decrease the voltage from 5 V. When full blanking is applied to #13, measure
the voltage.
G22 E / W Output Self-Diagnosis
A
Connect a 5-V external power supply to #23. Read D2 in bus read mode. (VBUS EWOFF)
When the external power supply connected to #23 is disconnected, read D2 in bus read mode.
Ensure that an E / W waveform is output from #22. (VBUS EWON)
G23 V-Out Output Self-Diagnosis
A
Connect a 9-V external power supply to #24. Read D3 in bus read mode. (VBUS VOFF)
When the external power supply connected to #24 is disconnected, read D3 in bus read mode.
Ensure that a V-out waveform is output from #25. (VBUS VON)
G24 Vertical Blanking Check
A
1)
Set the subaddress (0C) data to (81).
2)
When the subaddress (11) D4~D0 are changed from 0000 to 1111, check that the #13 blanking stop phase begins. (VBLK1)
3)
When the subaddress (12) D4~D0 are changed from 0000 to 1111, check that the #13 blanking start phase begins. (VBLK2)
G25 V Centering DAC Output
A
1)
Set the subaddress (13) data to (00) and measure the #21 voltage V21L.
2)
Set the subaddress (13) data to (80) and measure the #21 voltage V21M.
3)
Set the subaddress (13) data to (FE) and measure the #21 voltage V21H.
G26 V NFB Pin Input Current
A
Connect a 9-V VCC via a 100-k resistor to #25. Measure the sink current on #25
according to the voltage difference of the 100-k resistance.
I25 = V / 100 k
