Complete setup This voltage and current signal generator provides a complete testing solution, offered in Type 1 (battery not included) and Type 2 (battery included) options to suit your needs. Userfriendly display A 4digit definition digital display shows voltage and current with adjustable brightness levels from 1 to 8, ensuring clear visibility in various lighting conditions. Flexible power options Three power supply methods support different environments: external DC 5V input, a builtin lithium battery, and compatibility with DC 15–30V sources for flexible operation. Easy parameter saving Program and save voltage and current values with a single press of the encoder, eliminating the need to reenter settings after restart. Applications and scenarios Benchtop electronics testing: generate precise voltage and current profiles to verify regulators, DACs, ADCs, and power rails during development and debugging. Device development and verification: simulate realworld load conditions and verify responses of power management circuits and drivers. Educational demonstrations: illustrate signal generation, voltage/current regulation, and testing concepts in training labs or classrooms.
