Used KEITHLEY 263 #9101470 for sale

KEITHLEY 263 is a precision electronic test instrument built for measuring current. Its capabilities include AC/DC low-level current measurements, current sourcing, fast response, accuracy, and high slew rate, making it ideal for a variety of lab applications and research projects. With an open-loop 10V source, this model can both source and measure current from 0.5nA to 3A. 263 features a low-level measurement of 0.33nA/V using a combination of 10 ohm and 100 ohm resistors and a double current-to-voltage conversion technique. This technique provides an exceptional signal-to-noise ratio for current signals. KEITHLEY 263 also has a wide input dynamic range to accommodate a variety of applications from low currents to higher currents. It provides a 3V output range from 10V and is suitable for sourcing capacitor discharges and setting debug breakpoints. It can drive an LED to 10mA and load capacitors at 1mA per second up to 1F. It also has an LPF input stage with excellent high-sensitivity noise reduction that can achieve an extremely low input current noise measured in the nA range. 263 has an integrated temperature-compensated voltage-reference unit that provides current measurement accuracy over the temperature range of -55°C to +125° C, and accuracy over the full operating range of the device. The wide operating temperature range allows for long-term stable measurements with a minimum of calibration. Furthermore, the output of the instrument contains both true-rms and peak voltage measurements so that the user can identify high-frequency components or transients. KEITHLEY 263 provides digital control via a remote-control interface, allowing communication with other instruments or software. It also has onboard memory which can store up to sixteen measurement settings. The piece of equipment also comes with diagnostic indicators such as an under and over-range indicator, an open loop indicator, and a compliance indicator to indicate when the output specifications of the instrument are exceeded. 263 is a powerful electronic instrument that can suit almost any low-level current measurement need.
