XGY Tek supplies XDA active directional antennas for YSA-P400 field workflows, precision RF test cables, network analyzer interconnects, LISNs, adapters, attenuators, and EMC pre-compliance accessories. XDA-1000 covers 500 MHz to 10 GHz and XDA-2000 extends coverage to 20 GHz with switchable amplification, attitude sensing, and antenna-factor loading.

The cable catalogue spans DC to 110 GHz with phase-stable series, amplitude stability below 0.05 dB in the stated handling condition, phase stability below 2 degrees on selected VNA cables, ruggedized stainless-steel or nylon armor options, and shielding effectiveness above 100 dB where specified.

Start accessory selection from the complete measurement path: target frequency, antenna or cable role, connector family, signal level, movement during measurement, correction data, and required acceptance evidence. For cable and LISN selection, see our RF test cable and accessory guide.

Frequently Asked Questions

Which RF cable series should I use for VNA calibration vs. production test?
For VNA calibration and metrology benches, choose our VT series precision VNA test cables - engineered for repeatable calibration accuracy with <2 degrees phase stability under flex. For production and field benches that get connected and disconnected frequently, the PT series precision test cables balance durability and performance. For high-vibration or moving environments - chamber rotators, AUT mounts, mobile racks - choose the GL series phase-stable cables with armored construction.
Which active directional antenna should I use with YSA-P400?
Choose the XDA-1000 for measurements from 500 MHz to 10 GHz and its 20 dB typical amplifier gain. Choose XDA-2000 when the workflow requires coverage up to 20 GHz; its typical amplifier gain is 16 dB. Confirm the selected model and operating mode before loading antenna-factor data.
What is a Line Impedance Stabilization Network (LISN) and why do I need one?
A LISN provides a defined RF impedance between the DUT mains input and the AC supply, isolates external noise, and routes the conducted emissions to a measurement port for spectrum or EMI receiver capture. The EM5040 series is the compact LISN used in CISPR 16 and MIL-STD-461 conducted emissions pre-compliance benches. Pair with one of our spectrum analyzers for a complete bench.
Do XGY RF cables ship with characterization data?
Insertion-loss, return-loss, phase data, certificate of conformance, and extended characterization options are confirmed during quotation. For high-end metrology applications we can also discuss individually serialized cables with extended characterization across temperature via the quote form.
When should I reject a low-cost RF test cable?
Reject it when connector repeatability, phase movement under flex, shielding, bend radius, or calibration evidence is not documented for the measurement you need. A cheap cable can be expensive if it moves the VNA calibration plane or hides a marginal DUT.
What should be checked when using a LISN in EMC pre-compliance?
Check the mains rating, current rating, defined impedance, measurement port path, grounding method, safety procedure, and receiver or spectrum-analyzer settings. Keep the LISN setup photo, cable routing, and instrument settings with the test record.
