2) Operation Check Procedure
Checking the SD-SDI Output
a) Turn on the power to the LT 443D.
b) Connect SD-SDI unit’s SIGNAL 1 to the SDI waveform monitor using a 75
Ω
coaxial
cable.
c) Use the [UNIT] key on the main frame front panel to select the SD-SDI unit.
d) Press the [FORMAT] key. Then, use the [
▲
] and [
▼
] keys to select “525i/59.94” or
“625i/50.00” and press the [ENTER] key. (Factory default setting: 525i/59.94)
e) Press the [COLOR BAR1] key on the main frame front panel several times to select
“COLOR BAR 75%.”
f) Switch the SDI waveform monitor to waveform display. Display the “COLOR BAR
75%” waveform and check that the waveform is normal.
g) Switch the SDI waveform monitor to status display. Check that the format of the
signal output from the SD-SDI unit is detected correctly and that no errors are
indicated for FORMAT, TRS, and other items.
h) Repeat steps f) and g) for SD-SDI unit’s SIGNAL 2.
Checking the SD-SDI BLACK Output (LT 443D-SDB Only)
a) Connect SD-SDI unit’s SDI-BLK 1 to the SDI waveform monitor using a 75
Ω
coaxial
cable.
b) Use the [UNIT] key on the main frame front panel to select the SD-SDI unit.
c) Press the [FORMAT] key. Then, use the [
▲
] and [
▼
] keys to select “525i/59.94” or
“625i/50.00” and press the [ENTER] key. (Factory default setting: 525i/59.94)
d) Switch the SDI waveform monitor to status display. Check that the format of the
signal output from the SD-SDI unit is detected correctly and that no errors are
indicated for FORMAT, TRS, and other items.
e) Repeat step d) for SD-SDI unit’s SDI-BLK 2.
