The HP/Agilent 6177C is a precision DC current source delivering stable, highly regulated output from 0 to 500 mA across a 0 to 50 V compliance range. Operating as both a constant current source and voltage-limited supply, it provides exceptional load and line regulation—better than 25 ppm of output plus 5 ppm of range setting—making it ideal for resistivity measurements, semiconductor characterization, electrochemistry, and electromagnetics applications where precise current control is essential.
