signal that can be viewed at any equivalent scale factor is the
Input Differential Mode Range plus the offset used. See Adding
Offset on the following page.
When using the AP034 with the ADPPS power supply on
oscilloscopes without ProBus interface, use the following table to
select the desired effective volts per division and determine the
offset available.
