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.
