VthCP Clamp Pulse Threshold Voltage
Turn down the SG5 input level gradually from 5.0 V
P-P
, monitoring the waveform output.
Measure the top level of input pulse when the output pedestal voltage turn decrease with unstable.
WCP Clamp Pulse Minimum Width
Decrease the SG5 pulse width gradually from 0.5
µs,
monitoring the output. Measure the SG5 pulse width (a point of
1.5 V) when the output pedestal voltage turn decrease with unstable.

Pedestal Voltage Temperature Characteristics1
Measure the pedestal voltage at 25°C. The measured value is called PDC1.
Measure the pedestal voltage at temperature of
−20°C.
The measured value is called PDC2.
Pedestal voltage temperature characteristics 1 is calculated by the equation below:

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.
Oaj1 OSD Adjust Control Characteristics1
Measure the amplitude output at OUT (29, 32, 35). The measured value is called VOUT (29, 32, 35), and is treated as
Oaj1.
∆Oaj1
OSD Adjust Control Relative Characteristics1
Relative characteristics
∆Oaj1
is calculated by the equation below:
∆Oaj1
= VOUT (29) / VOUT (32),
VOUT (32) / VOUT (35),
VOUT (35) / VOUT (29)
Oaj2 OSD Adjust Control Characteristics2
Measuring condition and procedure are the same as described in Oaj1.
∆Oaj2
OSD Adjust Control Relative Characteristics2
Measuring condition and procedure are the same as described in
∆Oaj1.
