Scalable PXI Microwave Signal Generator

27 July 2017 – Keysight Technologies announced the industry’s first scalable PXIe microwave signal generator with frequency coverage up to 44 GHz and modulation bandwidth up to 1 GHz for generating complex waveforms used in emerging 5G and aerospace and defense DVT applications. Exclusive DDS technology with the synthesizer VCO provides excellent phase noise performance. When combined with the baseband performance, the M9383A PXIe signal generator delivers 1 percent EVM, a critical measure of 5G modulated signal performance, for 800 MHz wide pre-5G waveforms.

Engineers can now create Keysight validated Verizon pre-5G standard (5GTF) compliant waveforms and 5G candidate waveforms, such as 8 x 100 MHz OFDM component carriers (CC), for the PXIe signal generator using Keysight’s Signal Studio or SystemVue software. The software also allows engineers to create custom waveforms for emerging wireless, 5G new radio (5G NR) and aerospace and defense applications.

The M9383A PXIe vector signal generator is integrated in Keysight’s 5G testbed reference solution, adopted by several 5G development teams working across the sub-6 GHz, 28 GHz, and 39 GHz bands.

“Wideband devices introduce new challenges in terms of signal quality, flatness and calibration,” said Ron Harrison, director of sales and marketing, Keysight Internet Infrastructure. “Working with key customers, we found the M9383A exhibits the performance and scalability needed for R&D to easily transition to DVT and manufacturing, bringing immediate value in cost of ownership.”

In addition to offering size and test speed benefits, the PXIe signal generator is scalable and upgradable. Engineers can add channels to either vector or analog configurations. Users also can upgrade frequency, bandwidth and other performance characteristics as signal standards evolve. Modulation bandwidths of up to 2 GHz are supported through external IQ inputs.

Keysight’s rapid repair turnaround, with industry-leading calibration, core exchange strategy and standard three-year warranty, maximizes system uptime to reduce the total cost of ownership.
