Time Measurements
Time measurements are provided in the "Measurements" dialog box, "Setup > Amp/
Time" tab.

Meas. type Symbol Description/Result
Rise time T
Rise
Rise time of the left-most rising edge of the waveform. This is the
time it takes the signal to rise from the low reference level to the
high reference level. Multiple measurement is possible.
Fall time T
Fall
Falling time of the left-most falling edge of the waveform. This is
the time it takes the signal to fall from the high reference to the low
reference. Multiple measurement is possible.
Pos. pulse T
PosPulse
Width of a positive pulse: time between a rising edge and the fol-
lowing falling edge measured on the middle reference level. The
measurement requires at least one complete period of a triggered
signal. Multiple measurement is possible.
Neg. pulse T
NegPulse
Width of a negative pulse: time between a falling edge and the
following rising edge measured on the middle reference level. The
measurement requires at least one complete period of a triggered
signal. Multiple measurement is possible.
Period T
Period
Time of the left-most signal period of the waveform measured on
the middle reference level. The measurement requires at least one
complete period of a triggered signal. Multiple measurement is
possible.
f
Frequency f
Period
Frequency of the signal, reciprocal value of the period.

Pos. duty cycle R
PosCyc
Positive duty cycle: Width of a positive pulse in relation to the
period in %. The measurement requires at least one complete
period of a triggered signal. Multiple measurement is possible.
