Mean
Amplitude (voltage) measurement of the arithmetic mean over the
entire waveform.
Minimum
Amplitude (voltage) measurement of the minimum amplitude. TypiĆ
cally the most negative peak voltage.
NAND
A logic (Boolean) function in which the output of the AND function is
complemented (true becomes false, and false becomes true). On
the digitizing oscilloscope, that is a trigger logic pattern and state
function.
Negative duty cycle
A timing measurement representing the ratio of the negative pulse
width to the signal period, expressed as a percentage.
Negative overshoot measurement
Amplitude (voltage) measurement.

Negative width
A timing measurement of the distance (time) between two amplitude
points Ċ fallingĆedge MidRef (default 50%) and risingĆedge MidRef
(default 50%) Ċ on a negative pulse.
Normal trigger mode
A mode on which the oscilloscope does not acquire a waveform
record unless a valid trigger event occurs. It waits for a valid trigger
event before acquiring waveform data.
NOR
A logic (Boolean) function in which the output of the OR function is
complemented (true becomes false, and false becomes true). On
the digitizing oscilloscope, that is a trigger logic pattern and state
function.
OR
A logic (Boolean) function in which the output is true if any of the
inputs are true. Otherwise the output is false. On the digitizing
oscilloscope, that is a trigger logic pattern and state function.
Oscilloscope
An instrument for making a graph of two factors. These are typically
voltage versus time.
PeakĆtoĆPeak
Amplitude (voltage) measurement of the absolute difference beĆ
tween the maximum and minimum amplitude.
Period
A timing measurement of the time covered by one complete signal
cycle. It is the reciprocal of frequency and is measured in seconds.
