PXIe vector transceiver cuts test times, boosts test density

October 02, 2015 // By Graham Prophet
Keysight Technologies’ VXT PXIe vector transceiver is a fully calibrated instrument module that provides vector signal generation and analysis in four slots. Factory calibration of integrated instrument module ensures specified performance and accuracy in wireless manufacturing test.

With accelerated measurements and deep software, the VXT is intended for rapid solution creation and faster throughput in manufacturing test of wireless components and "Internet of Things" (IoT) devices.

System developers can create test solutions for power amplifiers (PA) and front-end modules (FEM) using the VXT's ready-to-run software and FPGA-accelerated measurements. To reduce programming time, Keysight provides an open-source PA Reference Solution that includes system configurations and example software routines for PA and FEM testing. These capabilities accelerate time to insight and reduce effort compared to general-purpose alternatives.

To accelerate test throughput, the VXT includes features such as real-time FFTs that enable high-speed measurements of signal power and adjacent-channel power ratio (ACPR). For faster automated testing, a built-in servo routine quickly reaches an accurate, optimised final setting for 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 DIO 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 matrices.

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, they can troubleshoot test setups using detailed displays in compatible X-Series measurement applications and the 89600 VSA software.

The VXT PXIe vector transceiver has a starting price of $36,400 for the 3.8 GHz model.
