Introduction
This testing was performed in order to evaluate the high-frequency electrical performance
SuperFly connectors in differential signaling applications. This report outlines frequency domain
performance metrics such as insertion loss (IL), return loss (RL) and crosstalk, as well as time-
domain performance metrics including impedance and eye pattern.
Product Overview
Glenair Series 88 SuperFly cordsets are the new standard for high performance, ultraminiature
interconnection systems. These lightweight, ultra-flexible connectors and cables are ideally
suited for battlefield and other high-performance applications.
Test Configuration
PC tail receptacles (PN 880-032R) were assembled onto the PCB test fixture. Test cables were
created using SuperFly plugs (PN 880-001P) with contacts terminated directly to low-loss 90Ω
nominal 30AWG twisted pair cable. A more detailed description of the test setup can be found
on page 13.

Performance Summary
Insertion loss (IL) data has been divided by two to show the performance of a single mated pair
of contacts terminated to 6 inches of cable. Insertion loss due to the test fixture PCB has been
de-embedded.
Parameter Results
Insertion Loss – Nano Contacts -3dB @ 3.9 GHz
Electrical Bandwidth* 8Gbps
Insertion Loss –Micro Contacts -3dB @ 2.9 GHz
Electrical Bandwidth* 6Gbps
Insertion Loss – Size 23 Contacts -3dB @ 2.1GHz
Electrical Bandwidth* 5Gbps
* The connector system electrical bandwidth is based on the -3dB insertion loss point of a single
mated pair, rounded up to the nearest 0.5GHz to account for test system loss that could not be
de-embedded from the results. The frequency is then doubled to determine an approximate data
rate in gigabits per second (Gbps). For example, a connector with a -3 dB point of 2.1GHz would
have a speed rating of 5.0Gbps.

APPENDIX B – Test System Description
A test fixture printed circuit board was designed specifically for this analysis. All traces to SuperFly contact pairs were designed to a nominal 50Ω ± 5% single-ended impedance but used in pairs for a 100Ω differential impedance.
All tests were performed using the Agilent E5071C ENA network analyzer with option TDR. All frequency domain data (IL, RL, NEXT, FEXT) has a 2% smoothing filter applied within the network analyzer. Device under test (DUT) includes two mated connector pairs (PNs 880-032R and 880-001P) with 12 inches of low-loss 90Ω±10Ω cable.
Test fixture and test cables were connected to the Agilent E5071C ENA Network Analyzer via high-performance 50-ohm coaxial test cables with SMA connectors. The system configuration is shown in the block diagram below:

APPENDIX C – Data Acquisition Methods
Frequency Domain (S-Parameter) Procedures
To ensure precise and repeatable data acquisition, extreme care was taken in the test fixture
design along with the calibration and testing procedure. A full calibration from 300kHz to 20GHz
was performed prior to testing using the Agilent N4433A eCal module. After calibration, test leads
were connected to the test fixture and applicable data was observed and saved into a .csv file.
At the completion of testing the acquired data was loaded into a spreadsheet for analysis and
figure generation.
Figure 6: Network analyzer with eCal module
Time Domain Procedures
Historically, dedicated TDR equipment was necessary to analyze time-domain response of RF
systems. The Agilent 5071C used for this testing contains software package “option TDR” which
mathematically derives time-domain information from acquired frequency domain data (S-
parameters). Even with bandwidth-limited data and a finite number of sample points, option TDR
offers a very accurate TDR representation. This also allows for generation of simulated eye
patterns to determine jitter and skew performance in relation to high speed data transmission. In
this report, the relationship between risetime and bandwidth was determined by using Time X
Bandwidth = 0.446, an equation provided by Agilent for use with the 5071C.
