5.2.5.2 Measurement Ranging
Measurement range is determined by the relationship between measurement auto range ON/OFF and the
Source/Measurement function.
NOTE: For Pulse source and Pulse-sweep source mode, the range is always fixed even when the measurement
auto range is set to ON.
1. Operating Range for Measurement Auto Range
When the measurement auto range is enabled, the upper and lower range levels are within ±20 digits
of the values shown in the table below.
