For a pulse waveform, the accuracy of any individual data point in the buffer depends on the rise time of the pulse. For a current
pulse of 1.4A with a rise time constant of 50µs, the error in measurement of a single data point during the rise time is ≈ 10mA.

May be reduced by changing the default conditions of 2048 data points but measurement uncertainty due to noise will increase.
