Bias-T included in Network Analyzer
With a completely new design of the optical test set together
with the newest ENA based network analyzer, the N4374B
guarantees excellent electro-optical measurement perfor-
mance. It’s the excellent accuracy that improves the yield from
tests performed with the N4374B, by narrowing margins need-
ed to pass the tested devices. NIST traceability ensures world-
wide comparability of test results.
The fully integrated “turnkey” solution reduces time to mar-
ket, compared to the time-consuming development of a self-
made setup.
In addition a unique new calibration concept significantly
reduces time from powering up the LCA until the first cali-
brated measurement can be made. This increases productiv-
ity in R&D and on the manufacturing floor.
By optimizing the electrical and optical design of the N4374B
for lowest noise and ripple, the accuracy has been improved
by more than a factor of 5 compared to the 8702 series LCA
and is now independent of the electrical reflection coeffi-
cient of the device under test.
The advanced optical design together with temperature-
stabilized transmitter and receiver ensures repeatable mea-
surements over days without recalibration.
Using the advanced measurement capabilities of the net-
work analyzer, all S-parameter related characteristics of the
device under test, like responsivity, ripple, group delay and
