Keithley meets a broad range of needs with:
General purpose bench and system power supplies that provide an excellent combination of performance, versatility, and ease of use. Get superior accuracy, 0.1mA current measurement resolution, external trigger, and both USB and GPIB interfaces. Have such convenience features as display of both setting values and actual output values, a keypad for fast data entry, and list mode sequence operation.
Battery simulating/fast transient response power supplies designed to test portable, battery-operated products such as smartphones and wireless chipsets, Bluetooth headsets, tablet computers, digital cameras, and GPS receivers. Capture load current pulses as narrow as 50µs and sleep mode currents as low as a few µA. Simulate a discharged battery to test charger control circuitry.
High voltage supplies with outputs up to 10,000V to facilitate high voltage device and material testing, as well as high energy physics experimentation.
