摘要: A hand held data collector and analyzer achieves superior stability, accuracy reliability through the use of a fixed frequency anti-aliasing filter two analog to digital converters, one for high signals low signals. Efficient filtering decimation is achieved by providing specialized hardware filters decimators implementing software in processor. true zoom method employed take advantage capabilities, independent signal processors operate serially on incoming further reduce demands central processing unit. In addition, RAM system memory formatted as pseudo-card facilitate PCMCIA card or memory.
