The E5081A ENA-X midrange network analyser provides integrated modulation distortion analysis

The Keysight E5081A ENA-X is a midrange vector network analyser for fast, accurate error vector magnitude (EVM) measurements

Demand for faster data speeds with ultra-low latency is pushing the next generation of wireless communications systems to operate at higher radio frequencies (RF). To ensure 5G New Radio (NR) transmitters meet these operational demands, RF engineers must fully test the design and performance of components such as power amplifiers (PA). Obtaining measurements for PAs under realistic conditions can be time consuming, requiring multiple instruments and test setups. In addition, acquiring the precise EVM measurements needed to certify PA conformance to 5G standards requires using a high-performance VNA.

The Keysight ENA-X addresses this need by giving RF engineers a midrange network analyser with integrated modulation distortion analysis offering full vector correction at the device under test (DUT) plane in a single test setup. With a unique architecture, the ENA-X can perform multiple measurements with a single connection, which simplifies test setup, drives repeatability, and speeds testing.
