Used KEITHLEY 6221 #9223220 for sale

KEITHLEY 6221 current source is a powerful electronic test equipment that has been designed to provide accurate and repeatable current sourcing for a wide range of test and measurement applications. The source can be used to measure current in milliamperes (mA) up to 10 amperes (A) with 10 microampere (µA) resolution. The model 6221 can be remotely programed either manually or via a computer using a GPIB, RS232, or USB interface. The high-frequency performance of KEITHLEY 6221 source ensures performance accuracy with a wide range of loads and over a wide frequency range from DC to more than 5MHz. This performance is also consistent, even after extended operating times and heavy currents, making it a reliable source for precision testing and measurement. 6221 sources have an adjustable sensitivity range of 20 mV/V to 5 V/V with a low-range resolution of 10mV/V. These features make it ideal for applications that require high-resolution such as semiconductor testing, sample and hold tests, and strain gage bridge testing. The source also features a programmable slew rate which can provide a dynamic range of up to 0.1 down to 10 ms with a 10 dB rise time of 50 ms. This feature is ideal for controlling dynamics and oscillations for sensitive circuitry. KEITHLEY 6221 also benefits from a built-in protection system which ensures complete protection from over-voltage, over-current, and over-temperature conditions. This system prevents any damage to the source or measurement equipment from any fault conditions during testing or use. 6221 source also features a variety of safety features including automatic output shut down on over-voltage or over-current, an adjustable auto-restart feature, and input fusing system to protect against phase surprises. The design benefits of KEITHLEY 6221 source make it ideal for applications that require fast, repeatable, and reliable current sourcing with excellent accuracy. Whether used in laboratory environments or for industrial settings, 6221 current source can deliver reliable performance in any environment.
