Picoammeter/Voltage Source

The 5½-digit Model 6487 Picoammeter/Voltage Source improves on the measurement capability of the award-winning Model 6485, and adds a high resolution 500V source. It provides higher accuracy and faster rise times than the 6485, as well as a damping function for use with capacitive devices. With eight current measurement ranges and high speed autoranging, this cost effective instrument can measure currents from 20fA to 20mA, take measurements at speeds up to 1000 readings per second, and source voltage from 200µV to 505V.Features：Rear panel triax input:Allows the picoammeter to be used in floating operation, up to 500VWhen not floating, the triax to BNC adapter allows inexpensive, easy-to-use BNC cables to be usedBuilt-in Trigger Link interface:Simplifies synchronizing with other instruments and voltage sourcesCombines six independent selectable trigger lines on a single connector for simple, direct control over all instruments in a systemDisplay on/off switch, when switched off, helps avoid introducing light that could significantly reduce the accuracy of the resultsOne-touch front panel design allows functions to be configured easily with the push of a button, without complicated function menus10fA resolution5-1/2 digit resolution<200μV burden voltageAlternating Voltage method ohms measurementsAutomated voltage sweeps for I-V characterizationFloating measurements up to 500VUp to 1000 readings/secondBuilt-in Model 486 and 487 emulation modeIEEE-488 and RS-232 interfaces make for easy instrument integration into automated test and measurement systemsScaled voltage analog output allows transmission of measurement results to devices like DMMs, data acquisition cards, oscilloscopes, or strip chart recordersDigital I/O
