Transmission Line Pulsar

The Barth Model 4002 Transmission Line Probe (TLP) test system is used as a pulse type curve tracer to measure the current-voltage characteristics designed into ESD protection circuitry. This new hardware was designed to fit the needs of present users of TLP who need a repeatable system that produces faster test results.

The test system consists of a Tektronix Model TDS-620B 500 MHz digitizing oscilloscope, the Barth Model 40021 pulse generator and control box, a Keithley Model 248 HV source, and a Keithly Model 487 picoammeter/voltage source. The tester is supplied with a 48-pin DIP socket that can accommodate .3 in., and .6 in. width packages. It can be used for smaller DIP packages with the use of pin renumbering overlays. Sockets for packaged devices are located in a pullout drawer in the instrument cabinet.
