Note 1:
Maximum throughput scanning to PC memory is machine dependent. While the majority of XP
equipped PC’s we tested allowed acquisition at the maximum rates, a few would not. The lowest
maximum rate we observed on an XP equipped PC during multi-channel testing was 95 kS/s,
aggregate. The rates specified are for Windows XP only. Maximum rates on operating systems that
predate XP may be less and must be determined through testing on your machine.
Note 2:
Actual values used for calibration are measured and stored in EEPROM.
