Measurement Ranging
The measurement range is determined by the relationship between the measurement auto range ON/OFF
and the source/measurement function.
NOTE:
For the pulse source or pulse sweep source mode, the range is always fixed even when the measurement
auto range is set to ON.
1. Operating range for the 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.
