PASCO Solution:

ScienceWorkshop 750 Interface Performance Comparison

Frames/Second at 5 ms/div Frames/Second at 0.02 ms/div Maximum Sustained Sampling Rate [samples/sec]
Adaptec 2906 SCSI Card ~13 ~64 10,000
USB cable 750 ~7 ~11 4,000
Serial 750 ~2 ~2 500

Notes:

  • Frame Rates were determined using the Scope display.
  • Test Computer: P4, 1.6 GHz, 256 Mb RAM, Windows 2000
  • Frame rates for Oscilloscope Display were with one sensor selected.
  • Maximum Sampling Rate was tested for 10 seconds. Voltage Sensor with no displays.
  • Sampling rates above 20kHz were really designed for use with DataStudio's scope display.
