MEASURE: This oscilloscope provides various automatic measurements. Automatic
measurements are taken over the entire waveform record, or the area specified by
cursors.
Select the different measurement by pressing F1 to F5 softkey. Maximum 10
measurements can be displayed simultaneously (if both Channel 1 and Channel 2
are connected with signal). There are fifteen measurements can be selected by each
softkey individually. And each softkey menu can display the same measurement for
both channels.
z
Vpp: Vmax-Vmin (over the entire waveform).
z
Vamp: Vhi-Vlo (over the entire waveform).
z
Vavg: Average voltage of the first cycle of the signal.
z
Vrms: The true Root Mean Square voltage over the entire waveform or specified
area.
z
Vhi: Voltage of the global high value.
z
Vlo: Voltage of the global low value.
z
Vmax: Voltage of the maximum amplitude. The positive peak voltage measured
over the entire waveform.
z
Vmin: Voltage of the minimum amplitude. The negative peak voltage measured
over the entire waveform.
z
Freq: Frequency measurement for the first cycle in the waveform or specified
area. The frequency is reciprocal of the period and measured in Hertz (Hz).
z
Period: Timing measurement takes for the first complete signal cycle to happen
in the waveform or specified area. The period is reciprocal of the frequency and
measured in seconds.
