Tr1 Pulse Characteristics1 Tr1
Control the contrast in order that the amplitude of output signal is 2.0 VP-P
.
Control the brightness in order that the Black level of output signal is 1.0 V.
Measure the time needed for the input pulse to rise from 10% to 90% (Trin) and for the output pulse to rise from 10% to
90% (Trout) with an active probe.
Pulse characteristics Tr1 is calculated by the equations below:
Tr1 = (Trin)2 − (Trout)2 (ns)
√
ΔTr1 Relative Pulse Characteristics1 Tr1
Relative Pulse characteristics ΔTr1 is calculated by the equation below:
ΔTr1 = VOUT (2) − VOUT (5),
VOUT (5) − VOUT (9),
VOUT (9) − VOUT (2)
Tf1 Pulse Characteristics1 Tf1
Measure the time needed for the input pulse to fall from 90% to 10% (Tfin) and for the output pulse to fall from 90% to
10% (Tfout) with an active probe.
Pulse characteristics Tf1 is calculated by the equations below:
Tf1 = (Tfin)2 − (Tfout)2 (ns)
√
ΔTf1 Relative Pulse Characteristics1 Tf1
Relative Pulse characteristics ΔTf1 is calculated by the equation below:
ΔTf1 = VOUT (2) − VOUT (5),
VOUT (5) − VOUT (9),
VOUT (9) − VOUT (2)
