Performance Tests
Performance tests are intended to test various DaqBook functions with the current device
configuration. These tests give quantitative results for each supported functional group.
The results represent maximum rates at which the various operations can be performed.
These rates depend on the selected parallel port protocol and will vary according to port
hardware capabilities.
• ADC FIFO Input Speed – tests the maximum rate at which data can be transferred
from the DaqBook’s internal ADC FIFO to computer memory through the parallel
port. Results are given in samples/second, where a sample (2 bytes in length)
represents a single A/D value.
• Digital I/O Input Speed – tests the maximum rate at which DIO input data can be
transferred from the DaqBook’s Digital I/O ports to computer memory through the
parallel port. Results are given in bytes/second.
• Digital I/O Output Speed – tests the maximum
rate at which DIO output data can be
transferred from the computer’s memory to the DaqBook’s Digital I/O ports through the
parallel port. Results are given in bytes/second.
