OTr OSD Pulse Characteristics1

Measure the time needed for the output pulse to rise from 10% to 90% (OTr) with an active probe.

OTf OSD Pulse Characteristics2

Measure the time needed for the output pulse to fall from 90% to 10% (OTf) with an active probe.

Oadj1 OSD Adjust Control Characteristics1 (Max.)

Measure the amplitude output at OUT (26, 28, 30). The amplitude is called VOUT (26, 28, 30).

The measured value is called Oadj1.

∆Oadj1 OSD Adjust Control Relative Characteristics1

Relative characteristics ∆Oadj1 is calculated by the equation below:

∆Oadj1 = VOUT (26) / VOUT (28),

VOUT (28) / VOUT (30),

VOUT (30) / VOUT (26)

Oadj2 OSD Adjust Control Characteristics2 (Typ.)

Measuring condition and procedure are the same as described in Oadj1.

∆Oadj2 OSD Adjust Control Relative Characteristics2

Measuring condition and procedure are the same as described in ∆Oadj1.

Oadj3 OSD Adjust Control Characteristics3 (Min.)

Measuring condition and procedure are the same as described in Oadj1.

∆Oadj3 OSD Adjust Control Relative Characteristics3

Relative characteristics ∆Oadj3 is calculated by the equation below:

∆Oadj3 = VOUT (26) − VOUT (28),

VOUT (28) − VOUT (30),

VOUT (30) − VOUT (26)

VthOSD OSD Input Threshold Voltage

Decrease the SG6 input level gradually from 5.0 VP-P, monitoring the output. Measure the top level of SG6 when the

output is disappeared. And increase the SG6 input level gradually from 0 VP-P. Measure the top level of SG6 when the

output is appeared. The measured value is called VthOSD.

OBLK Black Level Difference in OSD BLK on/off

Calculating the black level voltage minus the output voltage of high section of SG6 it makes VOUT (26, 28, 30). The

calculated value is called OBLK.

∆OBLK Relative OBLK

Relative characteristics ∆OBLK is calculated by the equation below:

∆OBLK = VOUT (26) − VOUT (28),

VOUT (28) − VOUT (30),

VOUT (30) − VOUT (26)
