Impedance range
Impedance range mode
Two modes can be used to select the impedance range as shown in Table 3-5.
Available impedance range
The hold range has nine impedance ranges, but when option 001 is installed, it
has ten. The impedance range is selected according to the DUT’s impedance
even if the measurement parameter is capacitance or inductance.

Auto range 
(auto selection)
The E4980A/AL sets
the optimum
impedance range for
the impedance of the
DUT.
You do not need
to select the
impedance
range.
The
measurement
time is longer
due to the
ranging time.
Hold range
(manual selection)
Measurement is
performed with a fixed
impedance range
regardless of the
impedance of the
DUT.
No ranging time
is required.
You need to
select a proper
range
depending on
the value of the
DUT.
