Keithley Introduces Dual-Channel Picoammeter/Voltage Source

By DE Editors

Keithley Instruments has introduced a dual-channel picoammeter with dual ±30V independent, non-floating bias sources and 1fA measurement resolution. The Model 6482 Picoammeter, the latest addition to Keithley’s line of sensitive instrumentation, provides two independent picoammeter/source channels in a 2U, half-rack enclosure, allowing simultaneous 6-1/2-digit measurements across both channels.

According to the company, it offers twice the channel density available from other high-speed, high-accuracy picoammeters for easier control and data aggregation and a lower cost of ownership, as well as higher measurement accuracy ( ±1% on the 2nA range) and a wider dynamic range (1fA to 20mA). At 4-1/2-digit resolution, users can take up to 900 readings/second on each channel.

The Model 6482 can provide ratio or delta measurements between the two completely isolated channels. These functions can be accessed via the front panel or the GPIB interface. For test setups with multiple detectors, this capability enables targeted control capabilities.

Current and voltage limits can be programmed to ensure device protection during critical points such as start of test, etc. It also provides Average and Median filters, which can be applied to the data stored in each channel’s separate 3000-point buffer memory.
