概述

The Model 6487 is a high resolution bus-programmable (RS-232 and IEEE-488) picoammeter. The Model 6487 has the following current measurement ranges: 8 ranges, from 20mA down to the 2nA range. The Model 6487 also has a built-in ±500V DC voltage source and an ohms function that includes an alternating voltage mode for enhanced high resistance measurement accuracy.
