i-CTS is a complete, single-vendor solution for high-speed cable production testing: a self-developed vector network analyzer, the MSW matrix switch and i-CTS test software. Frequency options of 26.5 \/ 40 \/ 67 GHz and 64 to 384 ports scale to any production line.<\/p>

One system, three self-developed pillars<\/h2>

VNA mainframe<\/h3>

Self-developed vector network analyzer up to 67 GHz with dynamic range up to 135 dB \u2014 overall performance on par with the industry benchmark.<\/p><\/div>

MSW matrix switch<\/h3>

Scales the system from 64 to 384 test ports so a single station covers complete multi-pair cable assemblies without re-cabling.<\/p><\/div>

i-CTS test software<\/h3>

Full support for PCIe 4.0\/5.0\/6.0, IEEE 802.3cd\/ck\/dj, CEI 4.0\/5.0\/5.1 and SAS algorithms, with self-developed IFD automatic de-embedding matching benchmark AFR\/ISD accuracy.<\/p><\/div><\/div>

The industry’s only 112G \u2192 224G upgrade path<\/h3>

Protect your investment: the VNA4435 mainframe returns to the factory for a hardware upgrade to 67 GHz in about one month \u2014 and ships back with a new 3-year warranty. No other cable test platform offers this.<\/p><\/div><\/div>

Proven consistency and stability<\/h2>

VNA4435 vs E5080B<\/h3>

Insertion loss difference < 0.02 dB, phase < 0.2\u00b0, return loss \u221245 dB across the full range.<\/p><\/div>

i-CTS vs PNA (N5224B)<\/h3>

On x8 DAC cable: insertion loss difference < 0.1 dB, impedance < 1 \u03a9, crosstalk envelope < 2 dB.<\/p><\/div>

14-day stability run<\/h3>

10 MHz\u201340 GHz, 4000 points: SDD21 variation only 0.13\u20130.15 dB, NEXT 0.99 dB, FEXT 0.91 dB, TDD11 0.01 \u03a9.<\/p><\/div><\/div>

Simplified calibration<\/h2>

Two-port electronic calibration kits complete a full 64-port calibration in just 36 steps \u2014 minutes instead of hours, with no manual reconnection errors.<\/p>

Customer case: global top-tier high-speed cable manufacturer<\/h2>

Testing PCIe 6.0 x8 16-pair cable assemblies (SlimSAS and server internal cables) at 10 MHz\u201326.5 GHz, 100 kHz IFBW, 2000 points: 128 tests (16 differential pairs + 7 crosstalk) completed in about 60 seconds \u2014 more than 15% faster than the incumbent system, with result deviation under 5%. The customer purchased more than 10 i-CTS systems.<\/p>
