Table 5.2.1 Typical Performance Criteria
Remark: Computer monitors and other lab equipment can cause noise spikes. If noise spikes
are present on the signal, try turning off the monitor or other equipment to verify that they are not
the cause. In addition, noise may be getting onto the signal through the cable that connects to
the parallel port of the computer.
