Logic Signal Sources

Types of Logic Signal Sources

• Pulse Pattern Generator (PPG)
• Data Timing Generator (DTG)

Logic sources are classified into pulse pattern generators and data timing generators. Pulse pattern generators drive a stream of square waves or pulses at very high frequencies from a small number of outputs. the high frequency and fast rise time capabilities of an advanced pulse generator make it an ideal tool to test high-speed digital equipment. The data timing generator generates volumes of binary information. The data timing generator is also called a pattern generator or data generator. It produces the streams of 1s and 0s needed to test computer buses, microprocessor IC devices, and other digital elements. The DTG can be used early in the product development cycle to substitute for system components that are not yet available.
