150 CompuScope 1610CCompuScope 1610C throughput & maximum PRFA number of applications require the CompuScope 1610C 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, 850 MHz processorï 256 MB RAMï 20 GB disk driveï Windows 98ï 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 CS1610C was operated using this application for many different capture depths and theresults are plotted as points in the graph below. The PCI transfer rate was calculated from the linear portion ofthe curve at high depths.PCI data transfer rate: 50 MB/sFigure 88: Maximum PRF vs. acquisition length
