Digital channe
l measurements do not have a user-settable midRef threshold. If you
specify a digital channel measurement that is not available on MSO/MDO4000/B
models (or MDO3000 and MDO4000C models with the MDO3MSO or
MDO4MSO option installed), measurement error 2200: measurement system
error occurs and 9.91e37 (not a number) is returned.
Conditions
The TOVershoot (total overshoot) measurement is supported on MDO3000,
MDO4000/B, or MDO4000C models with option SA3 or SA6 only.

Arguments
AMPlitude measures the amplitude of the selected waveform. In other words, it
measures the high value less the low value measured over the entire waveformor
gated region. This measurement is applicable only to the analog channels.
Amplitude = High - Low
AREa measures the voltage over time. The area is over the entire waveform or
gated region and is measured in volt-seconds. The area measured above the
ground is positive, while the area below ground is negative. This measurement is
applicable only to the analog channels.
BURst measures the duration of a burst. The measurement is made over the entire
waveform or gated region.
CARea (cycle area) measures the voltage over time. In other words, it measures, in
volt-seconds, the area over the first cycle in the waveform or the first cycle in the
gated region. The area measured above the common reference point is positive,
while the area below the common reference point is negative. This measurement
is applicable only to the analog channels.
CMEan (cycle mean) measures the arithmetic mean over the first cycle in the
waveform or the first cycle in the gated region. This measurement is applicable
only to the analog channels.
CRMs (cycle rms) measures the true Root Mean Square voltage over the first
cycle in the waveform or the first cycle in the gated region. This measurementis
applicable only to the analog channels.
