PXIe vector network analyzers are usually selected by three constraints: frequency coverage, number of physical RF ports, and chassis slot budget. XGY VNA modules cover compact two-port work, dense four-port production measurements, six-port multiport devices, and higher-frequency microwave validation.
Quick Recommendation
| Need | Recommended fit | Why it fits |
|---|---|---|
| Four-port production S-parameter test to 8.5 GHz | YNA-3084 Vector Network Analyzer | Four RF ports in a two-slot PXIe module with greater than 123 dB dynamic range. |
| Compact two-port VNA to 9 GHz | YNA-3092 Vector Network Analyzer Module | Single-slot two-port module with 10 MHz to 9 GHz coverage and up to 132 dB dynamic range. |
| Six-port multiport measurement to 9 GHz | YNA-3096 Vector Network Analyzer Module | Six physical RF ports in a dual-slot PXIe module for dense multiport DUTs and switch-reduced test plans. |
| Two-port microwave test to 20 GHz | YNA-3202 Vector Network Analyzer Module | Single-slot two-port module covering 10 MHz to 20 GHz, configurable to 22 GHz. |
Model Comparison
| Model | Ports | Frequency range | PXIe width | Recommended use |
|---|---|---|---|---|
| YNA-3084 | 4 ports | 10 MHz to 8.5 GHz | 2 slots | High-density four-port production and R&D measurements. |
| YNA-3092 | 2 ports | 10 MHz to 9 GHz | 1 slot | General two-port S-parameter measurement in compact PXIe systems. |
| YNA-3096 | 6 ports | 10 MHz to 9 GHz | 2 slots | Multiport RF front ends, couplers, switches, arrays, and reduced-switching fixtures. |
| YNA-3202 | 2 ports | 10 MHz to 20 GHz, configurable to 22 GHz | 1 slot | Microwave component validation above the 9 GHz class. |
How to Decide
Choose by port count before accessory count
A native four-port or six-port VNA can simplify fixtures and reduce switching compared with repeating two-port measurements through external RF switches. If the DUT has three or more relevant ports, compare the YNA-3084 and YNA-3096 before designing the switching matrix.
Choose by frequency ceiling
For sub-9 GHz production work, YNA-3092, YNA-3084, and YNA-3096 cover most common RF component measurements. Choose YNA-3202 when the test plan extends into microwave bands up to 20 GHz or needs the optional 22 GHz configuration.
Plan calibration and chassis layout early
PXIe VNA performance depends on calibration method, cable stability, fixture repeatability, and chassis integration. Confirm slot count, controller, trigger routing, calibration kit or ECal needs, and software interface before locking the final module choice.
Engineering Acceptance Checkpoint
Accept the VNA architecture only when the fixture and calibration plan match the port count. A YNA-3084 review should prove why 4 ports, 10 MHz to 8.5 GHz coverage, and 2 PXIe slots are the right boundary. A YNA-3092 or YNA-3202 review should explain why 2 ports are sufficient, while a YNA-3096 review should justify 6 physical ports instead of a switch matrix. The evidence package should include calibration method, cable family, fixture drawing, IF bandwidth assumption, port map, and at least 1 known-good S-parameter trace.
For a PXIe quote, send port count, frequency range, IF bandwidth needs, DUT fixture concept, chassis model, and preferred automation environment through Get a Quote. XGY Tek can size the VNA module, accessories, calibration path, and integration support together.

FAQ
Engineering FAQ
What should be defined before choosing a PXIe VNA?
Define frequency range, port count, dynamic range, calibration plane, fixture/de-embedding method, slot budget, trigger needs, and software/reporting interface.
When is a multiport VNA module worth choosing?
Choose multiport when the DUT has more than 2 RF ports, switch-matrix repeatability is a risk, or production time matters enough to avoid repeated reconnects.
What evidence should be kept with VNA acceptance?
Keep calibration kit details, calibration state, fixture or cable map, S-parameter export, reference-device result, port-power settings, and repeatability data.
