Meas. type Symbol Description Graphic / formula
Positive Pulse CntP+ Number of positive pulses on the display. 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.
N321
Negative Pulse CntP- Number of negative pulses on the display. The mean value
of the signal is determined. If the signal passes the mean
value, an edge is counted. A negative pulse is counted if a
falling edge and a following rising edge are detected.
N321
Positive Slope CntS+ Number of rising edges on the display. The instrument
determines the mean value of the signal and counts an
edge every time the signal passes the mean value in the
specified direction.
N321
Negative Slope CntS- Number of falling edges on the display. The instrument
determines the mean value of the signal and counts an
edge every time the signal passes the mean value in the
specified direction.
