For many years, instrument manufacturers have used “Standard Commands for Programmable Instrumentation” (SCPI) to control programmable test and measurement devices in test systems. The goal of SCPI is to provide a uniform and consistent command set for the control of test and measurement instruments.
Keithley’s Test Script Processor (TSP) is a flexible hardware/ software architecture that allows message-based programming, much like SCPI, with enhanced capabilities for controlling test sequencing/flow, decision-making, and instrument autonomy. TSP-enabled instruments operate like conventional SCPI instruments by responding to a sequence of commands sent by the controller.
