DaqBoard-ISA User’s Manual

Performance Tests

Performance tests check various DaqBoard 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. Note that the rates

depend on selected ISA protocol and will vary according to bus

hardware capabilities.

•

ADC FIFO Input Speed - Tests the maximum rate at which

data can be transferred from the DaqBoard’s internal ADC

FIFO to computer memory, through the PC’s ISA bus.

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 DaqBoard’s Digital

I/O ports to computer memory, through the PC’s ISA bus

slot. 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 DaqBoard’s Digital I/O ports, through the PC’s

ISA bus slot. Results are given in bytes/second.
