Keysight Technologies M9451A-DPD PXIe Measurement Accelerator with Digital Pre-Distortion & Envelope Tracking Gateware Data Sheet

02 Keysight M9451A PXIe Measurement Accelerator - Data Sheet Overview The M9451A-DPD shows what is possible when you combine state-of-the art FPGAs with Keysight Technologies, Inc. s trusted measurement expertise and PXIe high speed data handling. The trusted DPD and ET measurement algorithms were built after years of close cooperation with leading wireless manufacturing customers. As part of Keysight s RF PA/FEM Characterization and Test, Reference Solution, this combination provides unprecedented performance for demanding envelope tracking and digital pre-distortion measurements required for testing modern power amplifiers (PAs) and front-end modules (FEMs). Hardware acceleration provides better than 10x speed improvement over Keysight s previous host-based Reference Solution, with closed/open loop digital pre-distortion (DPD) and envelope tracking (ET) measurements taking just tens of milliseconds and overall measurement times less than 100 msec. Applications Power amplifier testing Front-end module testing Envelope tracking Digital pre-distortion Key Features The M9451A-DPD significantly speeds up DPD/ET test applications that use the N7614B Signal Studio Power Amplifier Test software. To simplify porting, the M9451A-DPD s application programming interface (API) is very similar to the N7614B API. Key features include: Digital Pre-Distortion Open or closed loop PA optimization techniques: Look up table (LUT) Fast peer-to-peer (P2P) data transfer to/from PXI signal generator and signal analyzer Envelope Tracking Hardware accelerated envelope tracking waveform generation Fast data transfer to arbitrary waveform generator (AWG)

Data cylinders are allocated blocks of IQ data in the M9451A memory. Rectangles represent algorithms implemented in the accelerator. Test software controls how data is processed by passing data handles associated with each data cylinder to the API method associated with each algorithm rectangle. Peer-to-peer (P2P) PCI Express technology is used to achieve fast data transfers between the M9451A memory and the M9381A PXIe vector signal generator (VSG) hardware. The ideal reference waveform, without pre-distortion, is first loaded into the M9381A PXIe VSG ARB memory and then transferred to the M9451A using P2P. After the model extraction algorithm computes a lookup table (LUT), or other coefficients, the pre-distorter creates a pre-distorted waveform in the PA In cylinder. P2P is used to transfer the pre-distorted waveform data to the VSG ARB memory. P2P PCI Express technology is also used to transfer measurement data from the M9391A or M9393A PXIe vector signal analyzer hardware to the M9451A hardware.

04 Keysight M9451A PXIe Measurement Accelerator - Data Sheet The M9451A-DPD PXIe measurement accelerator with DPD and ET gateware consists of two key parts: 1. M9451A PXIe measurement accelerator with an IVI driver and soft front panel (SFP). The IVI driver provides API access to accelerator configuration and initialization features. The SFP provides diagnostic information and tools to update the M9451A gateware. 2. Option DPD adds the ET and DPD acceleration software library and associated FPGA gateware that executes in the M9451A hardware. The library s API is modeled after the N7614B Signal Studio for Power Amplifier Test software. To utilize the M9451A-DPD as part of your test software, example open source code is available as part of the Keysight RF PA/FEM Characterization and Test, Reference Solution.

Technical Characteristics Definitions for characteristics Characteristics Best practices Additional information Characteristics describe performance that the product is expected to meet before it leaves the factory, but that is not verified in the field and is not covered by the product warranty. A characteristic includes the same guardbands as a specification. Characteristics are often referred to as typical or nomal values. Data represented in this document are characteristics unless otherwise indicated. To ensure proper cooling, use Keysight slot blockers (Y1212A), filler panels (Y1213A), and the air inlet module kit (Y1214A) in the chassis when there are empty slots. Keysight chassis and filler panels optimize module temperature performance. At environmental temperatures > 40ºC, chassis fans should be set to high. The specifications contained in this document are subject to change.
