Effective measurement range for each impedance range
The following shows the effective measurement range of each impedance
range, in which the E4980A/AL's measurement accuracy meets its
specifications.
When the impedance range is set manually, the optimum impedance range
should be selected by matching the impedance of the DUT to the effective
measurement range shown in
the impedance range is set to AUTO, the optimum impedance range is
automatically selected according to the impedance of each DUT.
The impedance range is limited by the test frequency setting when the test
signal level is less than or equal to 2V. When the impedance range and
test frequency are set under the above conditions, the test frequency must
be set first, followed by the impedance range. If you set the impedance
range first and then frequency, the resulting impedance range may not be
the one you wanted to set.

1. This can be set when the test signal level is more than 2 V.
2. When the test signal level is less than or equal to 2 V or 20 mA, it is 0 (zero).
3. When test frequency is more than 100 kHz and the test signal level is less than
or equal to 0.2 V (2 mA), it is more than 9.2 k.
4. When test frequency is more than 100 kHz and the test signal level is more than
0.2 V and less than or equal to 2 V (more than 2 mA and less than or equal to 20
mA), it is more than 27.6 k.
