Figure 77 Time Measurements
1. Period: Period for every cycle in waveform at the 50% level ,and positive slope.
2. Frequency: Frequency for every cycle in waveform at the 50% level ,and positive
slope
3. + Width: Width measured at 50% level and positive slope.
4. - Width: Width measured at 50% level and negative slope.
5. Rise Time: Duration of rising edge from 10-90%.
6. Fall Time: Duration of falling edge from 90-10%.
7. BWid: Time from the first rising edge to the last falling edge ,or the first falling edge to
the last rising edge at the 50% crossing.
8. + Duty: Ratio of positive width to period.
9. - Duty: Ratio of negative width to period.
10. Delay：Time from the trigger to the first transition at the 50% crossing.
11. T@L： Time from trigger of each transition at a specific level and slope, include:
Current, Max, Min, Mean, Std-dev.
Delay Measurements
Delay measurements measure the time different between arbitrary two channels,
including 10 kinds of delay measurements.
1. Phase: Calculate the phase difference between two edges.
2. FRFR: Time between the first rising edges of the two channels.
3. FRFF: Time from the first rising edge of channel A to the first falling edge of channel
B.
4. FFFR: Time from the first falling edge of channel A to the first rising edge of channel
B.
5. FFFF: Time from the first falling edge of channel A to the first falling edge of channel
B.
