CompuScope 85GC throughput & maximum PRF
A number of applications require the CompuScope 85GC to acquire data based on a rapidly occurring trigger
signal. These high Pulse Repeat Frequency (PRF) applications include imaging, radar, ultrasound and lightning
test.
The following test results were obtained using a computer configured as follows:
•
Pentium III, 850 MHz processor
•
256 MB RAM
•
20 GB disk drive
•
Windows 98
•
33 MHz, 32 bit CompactPCI
TM
bus
•
All slots support bus mastering
A C application program optimized for fast repetitive capture was used for throughput measurements.
The PRF rates shown below are for dual channel data acquisition, but data is being read out of the card from
only CH 1.
Figure 56: Maximum PRF vs. acquisition length
Notice that a PRF of about 100 Hz can be obtained for all possible capture depths.
