Keysight Technologies has launched its VXT PXIe vector transceiver, a fully calibrated instrument module that provides vector signal generation and analysis in four slots. The VXT is built for rapid solution creation and faster throughput in the testing of wireless components and internet of things devices.
System developers can easily create test solutions for power amplifiers (PAs) and front-end modules (FEMs) using the VXT’s ready-to-run software and field-programmable gate array measurements. In order to reduce programming time, Keysight provides an open-source PA Reference solution that includes proven system configurations and example software routines for PA and FEM testing. These capabilities accelerate the time to insight and reduce efforts as compared to general-purpose alternatives.
To accelerate test throughput, the VXT includes features such as real-time FFTs that enable high speed measurement of signal power and adjacent-channel power ratio. For faster automated testing, a built-in servo routine quickly reaches an accurate, optimised final setting for the PA output level. Up to four VXT modules can run in a single 18-slot PXI chassis. System developers can also create versatile single-chassis solutions that include one VXT running alongside Keysight’s digital input/output cards and its one-slot PXI VNA. VXT calibration is ensured because it is a fully integrated instrument module.
The VXT covers 60 MHz to 6 GHz and provides 160 MHz I/Q bandwidth in both vector signal generation and analysis. With a maximum of +18 dBm output power, the vector signal generator can compensate for signal losses through switch mat-rices. A variety of Keysight software titles support the VXT. For example, developers can simplify the creation of specific test signals using Signal Studio software. In addition, test set-ups can be troubleshooted using detailed displays in compatible X-Series measurement applications and the 89600 VSA software.
