PXI Expresscompatible compatible modules maintain hardware and software compatibility, with the exception ofmodule local bus.1. Verifying the System RequirementsTo use NI-DMM, your system must meet certain requirements. For more information on minimumsystem, recommended system, and supported application development environments (ADEs), refer tothe NI-DMM Readme file. Before installing NI-DMM, access this file on your NI-DMM driver softwareCDs. After you install NI-DMM, you can access this file at Start»All Programs»NationalInstruments»NI-DMM»Documentation.Note Waveform acquisition performance at full rate (1.8 MS/s) on the NI 407x depends highly onsystem-specific factors such as CPU speed, memory architecture, and system chipset characteristics.Simultaneous acquisitions on multiple NI 407x devices or acquisitions of longer durations require afaster processor or more memory. Other applications running at the same time also can affectperformance.
