11.1.2 Time Measurements
Time measurements includes 11 types of time parameter measurements.
Figure 11.4 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.
- Width : Width measured at 50% level and negative slope.
4. Rise Time : Duration of rising edge from 10-90%.
5. Fall Time : Duration of falling edge from 90-10%.
6. 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.
7. + Duty : Ratio of positive width to period.
- Duty : Ratio of negative width to period.
8. Delay Time from the trigger to the first transition at the 50% crossing.
9. T@L Time from trigger of each transition at a specific level and slope, include: Current, Max, Min, Mean, and Std-dev.
11.1.3 Delay Measurements
Delay measurements measure the time different between arbitrary two channels, including 10 types 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.
6. FRLR : Time from the first rising edge of channel A to the last rising edge of channel B.
7. FRLF : Time from the first rising edge of channel A to the last falling edge of channel B.
8. FFLR : Time from the first falling edge of channel A to the last rising edge of channel B.
