Keithley Instruments Inc. 6487 PICOAMMETER/VOLTAGE SOURCE
The Keithley 6487 Picoammeter/Voltage Source combines a sensitive picoammeter with a voltage source, offering current measurement capabilities from 20 fA to 20 mA and a voltage source range of 200 V. It features a high resolution 5½-digit display, built-in voltage source for biasing devices, and advanced filtering and averaging functions to improve measurement accuracy. The instrument is designed for applications such as photodiode, photomultiplier, and sensor characterization, insulation resistance testing, and leakage current measurements. The 6487 provides IEEE-488 and RS-232 interfaces for remote control and data acquisition, and includes safety interlocks and programmable limits for enhanced user protection.
