Tr1 Pulse Characteristics1 Tr1
Control the contrast in order that the amplitude of output signal is 2.0 V
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:
ΔTr1 Relative Pulse Characteristics1 Tr1
Relative Pulse characteristics ΔTr1 is calculated by the equation below:
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:
ΔTf1 Relative Pulse Characteristics1 Tf1
Relative Pulse characteristics ΔTf1 is calculated by the equation below:
Tr2 Pulse Characteristics2 Tr2
Change SW (2, 5, 9) from (a) to (b). Measuring condition and procedure are the same as described in Tr1.
ΔTr2 Relative Pulse Characteristics2 Tr2
Measuring condition and procedure are the same as described in ΔTr1, except of SW (2, 5, 9) condition.
Tf2 Pulse Characteristics2 Tf2
Change SW (2, 5, 9) from (a) to (b). Measuring condition and procedure are the same as described in Tf1.
ΔTf2 Relative Pulse Characteristics2 Tf2
Measuring condition and procedure are the same as described in ΔTf1, except of SW (2, 5, 9) condition.
