Test Active Components 50% Faster with the ENA-X Network Analyzer
Wideband signals and complex modulation schemes needed for high-volume, low-latency data rate devices make characterizing active components difficult. Traditionally, RF engineers use two instruments - a network and spectrum analyzer to characterize components fully.
Keysight recently launched the ENA-X network analyzer as a single-setup solution. The ENA-X enables fast and accurate EVM measurements, delivering high-power network analysis and linearity testing up to 44 GHz. The ENA-X minimizes your test cycle time and uniquely ensures active device test accuracy and repeatability using full vector correction—channel power and mismatch—at the DUT input.
Learn how our new ENA-X network analyzer can help you simplify your test setup and characterize active components up to 50% faster.
Double Your Throughput When Testing Power Amplifiers with Modulated Signals
Accelerating your 5G New Radio (NR) power amplifier development while ensuring conformance to stringent error vector magnitude (EVM) standards requires a consolidated test setup. Read this white paper to learn how to conduct high-power network analysis and low residual EVM measurements up to 44 GHz using the ENA-X network analyzer.
Simplify Your Power Amplifier Linearity Characterization With the ENA-X Network Analyzer
In wireless communication systems, the power amplifier occupies the last stage of the transmission chain to supply the required RF power to antennas. The PA is critical in determining the device's signal quality and battery life.
Linearity is also important in systems with high peak-to-average-power (PAPR) signals, such as those using orthogonal frequency-division multiplexing (OFDM) for the digital modulation scheme. The nonlinear response of the RF chain directly impacts error in the demodulation, leading to poor bit error rate performance. Additionally, nonlinearity creates spectral regrowth causing interference in other bands, so maintaining the linearity of the RF chain is crucial for the quality of wireless communication.

How Do You Characterize Low-Noise Amplifiers? With the ENA-X, It’s Simple.
Testing low-noise amplifier (LNA) 5G NR compliance requires noise figure and linearity measurements under modulated signal stimulus. System developers depend on LNAs across various applications, including wireless communications, sensor networks, navigation satellites, and radio telescopes. These LNAs amplify low-power signals while maintaining a high system signal-to-noise ratio (SNR). Along with common amplifier considerations like gain and linearity, LNAs must offer low noise figure functionality to preserve signal quality and system sensitivity.
In this white paper, learn how the ENA-X network analyzer's flexible hardware and advanced software capabilities simplify a low-noise amplifier’s performance characterization while improving measurement accuracy and repeatability.
Compare the Noise Figure Measurement Capability of Our Network Analyzers to Find Your Best Fit
The receiver quality and reliability of RF and microwave sub-systems such as satellite transponders or radar transmit/receive modules depends more on an LNA's noise figure than any other component's. Testing receivers operating in the FR1 and FR2 frequency bands requires accuracy and repeatability to ensure conformance with the latest standards. However, conventional active device measurement setups require multiple instruments.
Engineers measure noise figure using their choice of test instrument - a noise figure analyzer, spectrum analyzer, or vector network analyzer (VNA). The VNA offers S-parameter, gain compression, intermodulation distortion measurements, and noise figure using the cold-source measurement technique.
Learn how the ENA-X and PNA-X network analyzers simplify LNA characterization and how their noise figure measurement performance compares in this application note.
