Measurement
The available measurements for each channel are (from left to right):
Figure 8-62 Sample Measurement Screen
 Maximum – the highest level that the signal reaches
 Minimum – the lowest level that the signal reaches
 Peak To Peak – the difference between maximum and minimum
 Amplitude – the top value minus the bottom value
 Period – the duration of one cycle in a repeated pattern in the waveform
 Frequency – the number of signal occurrences per second
 Positive Duty Ratio – the ratio of positive pulse width to period width
 Negative Duty Ratio –the ratio of negative pulse width to period width
 Positive Pulse Width – the amount of time that the signal spends above its
average value
 Negative Pulse Width – the amount of time that the signal spends below its
average value
 AC RMS – the root mean square (RMS) value of the waveform minus the DC
Average
 True RMS – the root mean square (RMS) value of the waveform, including
the DC component
 DC Average – the average value of the waveform
