To make the best use of the ADC’s dynamic range, and therefore the most
accurate amplitude measurements, the displayed signal should completely
fill the display grid.
The fully calibrated and continuously adjustable input-signal
conditioning permits you to meet this requirement easily without loss
of calibration.
As an overlapping display of two full scale waveforms could become
quite confusing, the 9400A provides a dual grid option to be used in
applications where both channels are used simultaneously.
