E-Prime Timing Test Results

Parallel Port Adapters

The following are results of using E-Prime and the BBTK to send and receive various square waves.
In the sending paradigm, the E-Prime computer would send square wave values to the Parallel Port, which was connected to the BBTK and received through its Stimulus Capture application.
In the receiving paradigm, the E-Prime computer receive square wave values from the Parallel Port, which was connected to the BBTK and sent through its Event Generation application.
Each square wave was sent at 50% duty cycle of 1/2 the time up and 1/2 the time down. For example, a 2ms square wave would issue 1ms of high time and 1ms of low time, a 10ms square wave would issue 5ms of high time and 5ms of low time.
These are results from one paradigm under a set of hardware and circumstances.
The results of these tests do not imply that hardware will behave identically under all circumstances and configurations.
Each lab machine should be tested with appropriate equipment.
