Mean
Amplitude (voltage) measurement of the arithmetic mean over the entire
waveform.
Minimum
Amplitude (voltage) measurement of the minimum amplitude. Typically 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
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.

Low * Min
Amplitude

Negative width
A timing measurement of the distance (time) between two amplitude
points — falling-edge MidRef (default 50%) and rising-edge MidRef (default
50%) — 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
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 oscilloscope, that is a trigger logic
pattern and state function.
