Description: Fully Mated Circular RF Shielded Twisted Pair Twinax Cable Assembly
Test Calibration:
In this report, the system under test (SUT) includes the C28S cable assembly, CJT
connectors and footprint effects on a typical multi-layer PCB. PCB effects (trace loss)
are de-embedded from test data. Board related effects, such as pad-to-ground capacitance, are included in the data presented in this report.
Additionally, intermediate test signal connections can mask the connector’s true performance. Such connection effects are minimized by using high performance test cables
and adapters. Where appropriate, calibration and de-embedding routines are also used
to reduce residual effects.
Test fixture losses and test point reflections were removed from the data by use of Automatic Fixture Removal (AFR) application. The calibration board is shown below. The
measurements were performed under SOLT calibration and the test board effects were
included in the measurements. AFR application extracts fixture S-parameters from 2X
THRU measurement, and performs de-embedding on the DUT plus Fixture measurement to characterize only the DUT.

Adapter Use:
Each port uses at least one precision adapter capable of mating to the assembly under
test. Any supplementary adapter will contribute additional electrical characteristics to the
measured data. Any use of additional adapters is noted.
Definition of Assembly under Test:
The performance characteristics include the interface with adapters.
Port Designations:
The connector attached to port 1 of the VNA is “End 1” from the part number callout.
Insertion Loss is measured using S21 and Return Loss / VSWR is measured using S11.
Legend for Plots:
3 samples were tested. Base on the insertion loss, the min/max plots are shown for clarity in this report.
