The STA993X series is a 6 1/2 -bit low noise precision power supply that also has measurement capabilities, with a fixed measurement resolution of 4 1/2 bits. The instrument sets the output voltage/current or measures voltage/current/resistance through the touch screen, front panel keys and knob. Supports sweep output, pulse output, arbitrary waveform generation, trace buffer, math expressions, and graph drawing. The STA993X can be used as a DC (constant) voltage/current source, a swept voltage/current source, a pulse generator, an arbitrary waveform generator, and a multimeter.
