The CMicrotek µCP100/µCP120 are ideal for engineers developing wearable/portable devices, wireless "IoT" devices and energy harvesting powered devices. The µCP100 features a current range from 5nA to 100mA, the µCP120 is targeted at higher power applications such as WiFi with its 50nA to 800mA range. With a voltage range from millivolts up to 20VDC they can be used with all of the common logic power supply voltages and small battery technologies. The µCP100/µCP120 work with any scope with a standard BNC probe connector or can be used as a pre-amplifier for a data acquisition system for longer term tests such as voltage/temperature range testing.
