Introduction
The scope of this Startup Guide is to detail the processes of receiving and installing
the Keysight M9451A PXIe Measurement Accelerator. The M9451A PXIe
Measurement Accelerator using DPD Option (Digital Pre-Distortion & Envelope
Tracking Gateware) shows performance improvements when combining state of the
art FPGA’s with Keysight’s measurement expertise and PXIe’s high speed data
handling. As part of Keysight’s RF PA/FEM Characterization & Test, Reference
Solution, this combination provides enhanced performance for envelope tracking
and digital pre-distortion measurements required in testing modern power
amplifiers (PAs) and front-end modules (FEMs). Hardware acceleration provides
speed improvement over Keysight’s previous host-based Reference Solution, with
closed/open loop digital pre-distortion (DPD) and envelope tracking (ET)
measurements.
The key features of Keysight M9451A PXIe Measurement Accelerator are:
Hardware acceleration provides 10x DPD/ET speed improvement over
Keysight’s host-based RF PA/FEM Characterization & Test Reference
Solution.
Closed/open loop DPD and ET measurements can be performed in tens of
milliseconds thereby reducing overall test time to <100 ms.
DPD/ET algorithms created in cooperation with leading wireless
manufacturers.
Peer-to-peer connectivity with Keysight M9381A PXIe Vector Signal
Generator, M9391A PXIe Vector Signal Analyzer, and M9393A PXIe
Performance Vector Signal Analyzer modules.
Altera Stratix V “A7” FPGA with 4 GB DDR3 memory.
