Increasing Measurement Accuracy
and Time-Interval Measurement
Time-Interval Measurements
measuring the interval from the 10 percent level on one edge to the 90
percent level on some later edge is the same as the error in measuring rise
time.
Narrow pulse response
If you apply a narrow pulse to the input of the instrument, the waveform is
aected in three ways:
1. the height is incorrect
2. the 50 percent width is incorrect
3. the peak is shifted relative to the pulse as shown in Figure 9-6.
