Voltage parameters
DC Mean
The arithmetic mean of the entire waveform data.
Max
The signal's positive peak voltage.
(Difference between zero and highest value.)
Min
The signal's negative peak voltage.
(Difference between zero and lowest value.)
Peak-to-Peak
The signal's peak-to-peak voltage.
(Difference between highest and lowest value.)
High
The statistical maximum level recorded for all the cycles in the signal.
Low
The statistical minimum level recorded for all the cycles in the signal.
Amplitude
The voltage difference between the High and Low of the signal.
AC RMS
The true RMS value of the AC component of the signal is calculated and converted to voltage.
AC dBV
The measured signal (AC only) is converted to dBV (0dB= 1V).
AC dBm
The measured signal (AC only) is converted to dBm (0dB= 0.775V).
AC+DC RMS
The true RMS value of the wave (AC+DC) is calculated and converted to voltage.
AC+DC dBV
The measured signal (AC+DC) is converted to dBV (0dB= 1V).
AC+DC dBm
The measured signal (AC+DC) is converted to dBm (0dB= 0.775V).
