128 CompuScope 14100CCompuScope 14100C throughput & maximum PRFA number of applications require the CompuScope 14100C to acquire data based on a rapidly occurring triggersignal. These high Pulse Repeat Frequency (PRF) applications include imaging, radar, ultrasound and lightningtest.Gage has performed extensive repetitive capture benchmarks in single record mode. In this mode, the signal iscaptured into on-board CompuScope memory and the captured data are transferred through the PCI bus usingPCI bus mastering to PC RAM.Please note that much higher PRFs will be achieved using CompuScope Multiple Record mode.The following test results were obtained using a computer configured as follows:ï Pentium III, 500 MHz processorï 128 MB RAMï 20 GB disk driveï Windows NT 4.0 with SP6ï NT File Systemï 33 MHz, 32 bit CompactPCI TM busï All slots support bus masteringA C application program optimized for fast repetitive capture in single record mode was used for throughputmeasurements. The CS14100C was operated using this application in both single and dual channel mode formany different capture depths and the results are plotted as points in the graph below. The PCI transfer rateswere calculated from the linear portion of the curves at high depths.PCI data transfer rate (single channel): 80 MB/sPCI data transfer rate (dual channel): 50 MB/sFigure 78: Maximum PRF vs. acquisition length
