DaqBook User’s Manual

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.
