Scope measurements
AC RMS. The root mean square (RMS) value of the waveform minus the DC Average.
It is equivalent to a ripple measurement.
Cycle Time. PicoScope will attempt to find a repeated pattern in the waveform and
measure the duration of one cycle.
DC Average. The mean value of the waveform.
Duty Cycle. The amount of time that a signal spends above its mean value,
expressed as a percentage of the signal period. A duty cycle of 50% means that the
high time is equal to the low time.
Falling Rate. The rate at which the signal level falls, in signal units per second. Click
the Advanced button in the Add Measurement or Edit Measurement dialog to
specify the signal level thresholds for the measurement.
Frequency. The number of cycles of the waveform per second.
Fall Time. The time the signal takes to fall from the upper threshold to the lower
threshold. Click the Advanced button in the Add Measurement or Edit
Measurement dialog to specify the signal level thresholds for the measurement.
High Pulse Width. The amount of time that the signal spends above its mean value.
Low Pulse Width. The amount of time that the signal spends below its mean value.
Maximum. The highest level reached by the signal.
Minimum. The lowest level reached by the signal.
Peak To Peak. The difference between maximum and minimum.
Rise Time. The time the signal takes to rise from the lower threshold to the upper
threshold. Click the Advanced button in the Add Measurement or Edit
Measurement dialog to specify the signal level thresholds for the measurement.
Rising Rate. The rate at which the signal level rises, in signal units per second. Click
the Advanced button in the Add Measurement or Edit Measurement dialog to
specify the signal level thresholds for the measurement.
True RMS. The root mean square (RMS) value of the waveform, including the DC
component.
Mask Failures. A special measurement that counts the number of failed waveforms
in Mask Limit Testing mode. This measurement is added to the table automatically
when you use Mask Limit Testing, so there is usually no need to select it manually.
