mode as only one channel is used as the source.
Use the Individual measurement mode (page 76)
instead.
Digital Channels Only Frequency, Period, +Width, -Width and Duty
Cycle measurements are supported for digital
channels.
High Low Function
Background The High-Low function is used to select the
method for determining the value of the High-Low
measurement values.
Auto Automatically chooses the best
high-low setting for each
waveform when measuring.
Histogram Uses histograms to determine the
high-low values. This mode
ignores any preshoot and
overshoot values. This mode is
particularly useful for pulse-type
waveforms
