Area measurements
Access: [Meas] > "Meas Group" tab > "Amp/Time" category
Area measurements are voltage over time measurements.

Area between the waveform and a reference level ("Area level")
measured for one period, see also "Area" measurement. The
measurement requires at least one complete period of a trig-
gered signal. Multiple measurements are possible.
Counting
Access: [Meas] > "Meas Group" tab > "Amp/Time" category
Table 8-4: Counting measurements
Meas. type Symbol Description/Result
n
Pulse count The number of positive or negative pulses of the waveform, or of
both positive and negative pulses.
The mean value of the signal is determined. If the signal passes
the mean value, an edge is counted. A positive pulse is counted
if a rising edge and a following falling edge are detected. A neg-
ative pulse is counted if a falling edge and a following rising
edge are detected.
n
Edge count The number of positive or negative edges, or of both positive
and negative edges.
The instrument determines the mean value of the signal and
counts an edge every time the signal passes the mean value.
