The 3000CS is an advanced AC current source that addresses increasing demands on manufacturers to test products using real-world current profiles. By combining true current transconductance amplifiers with an advanced digital controller and harmonic power analyzer, the CS Series current sources are capable of performing tests that traditionally have been difficult to accomplish

The CS Series is completely microprocessorcontrolled and can be operated from a simple front panel keypad. An analog knob located next to the backlit alphanumeric LCD display allows output current or frequency to be slewed up or down dynamically

With precise current programming and regulation, high output current, multi-phase mode and built-in power analyzer measurement capabilities, the CS Series AC current sources address many AC current test applications. Additional features, like arbitrary waveform generation and transient generation make the CS Series the ideal source for demanding production test requirements. All CS Series AC Sources are equipped with IEEE-488 (GPIB), USB and RS232C remote control interfaces and support SCPI command language programming. An Ethernet interface is optional (-LAN Option).
