PNA and PNA-X Series Microwave Network Analyzers


Future-proof your microwave component testing

All members of the PNA family share a common software platform that makes it easy to choose just the right level of performance to match your budget and measurement needs. This commonality guarantees measurement consistency and repeatability and a common remote-programming interface across multiple instruments in R&D and manufacturing. All of the powerful PNA software applications can be added later to meet future test requirements.

Industry’s Most Advanced RF Test Solution

Reach for unrivaled excellence

Choose the leader in network analysis

The PNA-X Series of microwave network analyzers are the culmination of Keysight Technologies, Inc. 40-year legacy of technical leadership and innovation in radio frequency (RF) network analysis. More than just a vector network analyzer, the PNA-X is the world’s most integrated and flexible microwave test engine for measuring active devices like amplifiers, mixers, and frequency converters.

The combination of two internal signal sources, a signal combiner, S-parameter and noise receivers, pulse modulators and generators, and a flexible set of switches and RF access points provide a powerful hardware core for a broad range of linear and nonlinear measurements, all with a single set of connections to your device-under-test (DUT).

When you’re characterizing active devices, the right mix of speed and performance gives you an edge. In R&D, the PNA family provides a level of measurement integrity that helps you transform deeper understanding into better designs. On the production line, our PNAs deliver the throughput and repeatability you need to transform great designs into competitive products. Every Keysight VNA is the ultimate expression of our expertise in linear and nonlinear device characterization. Choose a PNA - and reach for unrivaled excellence in your measurements and your designs.

Network analysis technology down to the nanoscale

The PNA-X is also compatible with these Keysight measurement solutions:

  • Physical layer test system (PLTS) software to calibrate, measure, and analyze linear passive interconnects, such as cables, connectors, backplanes, and printed circuit boards.
  • Materials test equipment and accessories to help determine how your materials interact with electromagnetic fields, by calculating permittivity and permeability.
  • Award-winning scanning microwave microscope to create a powerful and unique combination for topography measurements of calibrated capacitance and dopant densities at nanoscale dimensions.

Multiple measurements with a single instrument

Replace racks and stacks

With its highly integrated and versatile hardware and re-configurable measurement paths, the PNA-X replaces racks and stacks of equipment - with a single instrument. One PNA-X can take the place of the following test gear:

• Network analyzer

• Spectrum analyzer

• Three signal sources

• Noise figure meter/analyzer

• Power meters

• Switch matrix

• Digital voltmeter

Benefits of a PNA-X-based solution

• Simpler test systems for... lower hardware and software costs, quicker development time and faster time to manufacturing , less downtime and lower maintenance costs ,smaller size and lower power consumption

• Faster test times for...improved throughput

• Higher accuracy for... better yields and better specifications

• Flexible hardware for... greater adaptability to future test requirements

Flexible Architecture

  1. Each test port includes test and reference couplers and receivers, source and receiver attenuators, and a bias tee, for maximum accuracy and flexibility.
  2. The built-in signal combiner greatly simplifies the setup for intermodulation distortion and X-parameter measurements. (PNA-X only)
  3. Internal pulse modulators enable integrated pulsed-RF testing over the full frequency range of the instrument, eliminating expensive and bulky external modulators.
  4. Extremely low-phase noise sources with DDS synthesizers enable to characterize active devices without using high-performance analog signal generators. ex. two adjacent tone IMD.
  5. Optional third source on 4-port PNA-X can be used as another signal source.(PNA-X only)
  6. Switchable rear-panel jumpers provide the flexibility to add signal-conditioning hardware or route additional test equipment to the DUT without moving test cables. (PNA-X only)
  7. Setting up pulse timing for the pulse modulators and internal IF gates is easy using the built-in pulse generators.
  8. Internal low-noise receivers, along with advanced calibration and measurement algorithms, provide the industry’s most accurate noise figure measurements. (PNA-X only)

PNA Series

The PNA Series of network analyzers offers industry-leading performance for testing amplifiers, mixers and frequency converters. The PNA Series provides a winning combination of excellent hardware and powerful measurement applications to measure a broad range of devices fast and accurately. All models are available in 2-port single-source and 4-port dual-source versions. Pulsed S-parameters are easy using built-in pulse modulators and pulse generators.

Highest performance

  • High source output power of +13 dBm at 1 GHz to +11 dBm at 67 GHz
  • High dynamic range: 134 dB at 20 GHz at test port
  • Low trace noise: 0.002 dB rms at 1 kHz bandwidth
  • Low receiver noise floor
  • High receiver compression level
  • Fast measurement speed: 3.6 to 23 psec/point
  • High stability: < 0.03 dB/°C

Innovative Applications

New capability of spectrum analysis application - Noise Power Ratio (NPR) measurements (S93090x/093/094B)

Challenges for amplifier noise power ratio (NPR) measurements

  • It requires a spectrum analyzer for the analysis, and the measurement takes a long time due to the need for lots of averaging of random, noise-based signals
  • It’s difficult and time-consuming to correct the flatness of the multi-tone input stimulus
  • The distortion floor in the notch may not be low enough, especially if a booster amplifier is used
