Effective measurement range for each impedance range for impedance
measurement
Figure 3-3 shows the range that can be displayed and the effective measuring
range for each impedance range while in the impedance mode (| Z |, R, X). For
example, 50-k DUT impedance can be measured using the ranges of 100 k
to 30 k, but the E4980A/AL’s accuracy specification is only met when using
the 30-k range. If this DUT is measured with the 100-k range, “OVERLOAD”
will be displayed.
