Model 6482 Dual-Channel Picoammeter/Voltage Source Specification

SPECIFICATION CONDITIONS

This document contains specifications and supplemental information for the Model 6482 Dual-Channel Picoammeter / Voltage Source instrument. Specifications are the standards against which the Model 6482 is tested. Upon leaving the factory, the Model 6482 meets these specifications. Supplemental and typical values are nonwarranted, apply at 23 °C, and are provided solely as useful information.

The Model 6482 provides two independent picoammeter/voltage source channels for a wide range of measurement applications. The Model 6482 includes an analog output jack on the rear panel for each channel.

Source and measurement accuracies are specified at the Model 6482 terminals under these conditions:

1. 23 °C ± 5 °C, < 70 percent relative humidity
2. After a one-hour warm-up period
3. Speed normal (1 NPLC)
4. A/D autozero enabled
5. Properly zeroed operation
6. Calibration period: One year
