Keysight Technologies has unveiled the E5081A ENA-X, a vector network analyzer (VNA) that produces error vector magnitude (EVM) measurements and assists in the analysis of 5G component designs, speeding up the process by as much as 50%. With the current need for ultra-low latency and ever-increasing data speeds, the next generation of wireless communications systems are expected to operate at higher radio frequencies. Engineers must fully scrutinize the design and performance of components like power amplifiers (PA) for 5G New Radio (NR) transmitters to guarantee they satisfy operational demands.
However, obtaining measurements for PAs under realistic conditions can be time-consuming. Multiple instruments and test setups are required, and precise EVM measurements needed to certify PA conformance to 5G standards necessitate the use of a high-performance VNA. The ENA-X offers an excellent solution for RF engineers, a midrange network analyzer platform with integrated modulation distortion analysis providing full vector correction at the device under test (DUT) plane in just one test setup. The device can perform multiple tests using just one connection, making the process simple, orderly, and quick.
The ENA-X offers several benefits, including an integrated solution with an upconverter, direct receiver access, and modulation distortion analysis software that facilitates the characterization of RF amplifier performance under complex modulation schemes in high-power systems. The device offers a single calibration run with just one connection, enabling the characterization of PA for 5G transmitters in the 5G NR FR1 and FR2 frequency bands by up to 50%. It also builds on Keysight’s metrology expertise with patented, custom monolithic microwave integrated circuits (MMIC) to provide the highest measurement accuracy, easily repeatable results, and the lowest residual EVM on the market.
Joe Rickert, VP, and GM of Keysight High Frequency Measurements Center of Excellence, extolled the virtues of the ENA-X, stating: “Combined with the powerful modulation distortion analysis software that was previously only available on our highest-performing PNA series network analyzers, the new midrange E5081A ENA-X VNA solution is ideal for power amplifier characterization for 5G transmitters. Thanks to its custom-built MMICs, the ENA-X provides the highest output power, dynamic range, and system stability needed by RF engineers without masking the performance of the power amplifier under test.”
The ENA-X’s streamlined setup is a reduction of complexity in the testing process, freeing up engineers to work on other projects and conduct more tests efficiently. The device’s accuracy and repeatability qualities prevent the need for repeated testing, saving time and resources. The ENA-X offers reliable and precise measurements for engineers, ensuring that the power amplifiers used in 5G transmitters conform to 5G transmission standards.
