Measure the output signal 0 IRE DC levels of the R
output (pin 36), G output (pin 37), and B output (pin
38) and record these as Vbias0* (V), where * : R, G,
and B, respectively.
Measure the output signal 0 IRE DC levels of the R
output (pin 36), G output (pin 37), and B output (pin
38) and record these as Vbias128* (V), where * : R,
G, and B, respectively.
Measure the output signal 0 IRE DC levels of the R
output (pin 36), G output (pin 37), and B output (pin
38) and record these as BAS80* (V), where * : R, G,
and B, respectively.
Measure the output signal 0 IRE DC levels of the R
output (pin 36), G output (pin 37), and B output (pin
38) and record these as BAS48* (V), where * : R, G,
and B, respectively.
Vbiassns * = (BAS80 * – BAS48 *)/32
Measure the output signal 0 IRE DC levels of the R
output (pin 36), G output (pin 37), and B output (pin
38) and record these as SBTPM* (V), where * : R,
G, and B, respectively.
Vsbiassns * = (BRTPC * – SBTPM *)
Measure the output signal 100 IRE DC amplitudes of
the R output (pin 36), G output (pin 37), and B output
(pin 38) and record these as DRVH* (Vpp), where * :
R, G, and B, respectively.
Measure the output signal 100 IRE DC amplitudes of
the R output (pin 36), G output (pin 37), and B output
(pin 38) and record these as DRVL* (Vpp), where * :
R, G, and B, respectively.
RGBout0 * = 20 log(DRVH */DRVL *)
