Measurement
The available measurements for each channel are (from left to right):
Figure 7-80 Sample Measurement Screen 1
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
