As an ultra-fast data acquisition device, the CompuScope card can convert analog signals must faster than the resulting data can be transferred to the PC's host memory. To solve this problem, the CompuScope card can be instructed to store the data in its on-board memory, until such time that the data can be transferred later. The amount of this high-speed memory determines the Record Length of data capture, i.e., how long a snapshot the CompuScope can take. See also Memory Depth and Samples .

Polarization Polarization refers to how the trace is displayed relative to the X axis. When polarization is normal, the channel is displayed exactly as captured. Inverting the polarization inverts the signal about the X axis for purposes of the display, without affecting the actual data. Post-trigger data is located to the right of the trigger marker. Pre-trigger data is located to the left of the trigger marker.
