Real-World Characterization Under Various Operating Conditions
Comprehensive analysis using
multi-channel/multi-trace
The 4-channel/4-trace capability helps you
setup and measure multiple parameters
under various operating conditions, such
as frequency, test signal level, and DC
level dependency. The measurement
results can be enlarged on the display
with one touch.
Frequency dependency
Frequency dependency is common in all
components because of the existence of
parasitics. The E4990A can sweep test
frequencies from 20 Hz to 120 MHz over a
wide impedance range. It enables accurate
evaluation of the frequency response
including the self-resonant frequency
point of components, such as capacitors
and inductors.
Test signal level dependency
The test signal (AC) applied may affect the
impedance characteristics of some devices.
The E4990A can sweep test signal voltage
from 5 mVrms to 1 Vrms (1 mV resolution),
or test signal current from 200 μArms to
20 mArms (20 μA resolution) to evaluate
test signal level dependency. The E4990A’s
ALC function accurately maintains the
applied test signal voltage or test signal
current. While the impedance of a device
might change during a sweep, the ALC
function insures that the signal level setting
is the actual signal level applied to the DUT.
DC level dependency is common in
semiconductor components such as
diodes and transistors. Some passive
components are also DC level dependent.
The E4990A can sweep DC voltage bias
from –40 V to +40 V (1 mV resolution),
or DC current bias from –100 mA to
+100 mA (40 μA resolution) to evaluate DC
signal dependency. The ALC automatically
maintains the applied DC voltage bias or
current bias.

Lower right: DC level dependency (0.1 μF capacitor, DC-level swept from 0 V to 10 V, frequency = 1 kHz, OSC level = 500 mV)
07 | Keysight | E4990A Impedance Analyzer - Brochure
Segment Sweep for Efficient Analysis
The segment sweep function allows you
to divide the sweep range into segments.
Each segment, including the frequency
range, number of points, averaging factor,
test signal level, and DC bias can be set
independently. This can be achieved with a
single sweep. The segment sweep setting
can also be exported to a CSV file.
Evaluation of a crystal resonator requires
that the nominal resonant/anti-resonant
frequencies and some spurious frequencies
be determined. You can perform a sweep
measurement for a specific range,
eliminating the ranges that aren’t needed.
Crystal resonator evaluation by segment sweep (64 MHz crystal, OSC level = 500 mV)
Equivalent Circuit Analysis
The purpose of equivalent circuit analysis
is to model the impedance versus frequency
characteristics with three or four
elements.
Seven different multi-parameter models
accommodate different types of devices
such as capacitors, inductors or resonators.
You can simulate the impedance trace
of your own equivalent circuit parameter
values and then compare it with an actual
measurement trace. The equivalent circuit
parameters can also be saved as a text file.
