Keithley 486
Analog/Digital Picoammeter 5.5 digt
Description
This Digit Autoranging Picoammeter is designed for low current applications where fast reading rates must be made.
It offers a speed of 180 readings per second.
Operation is fast and convenient.
Selectable analog and digital filters provide optimum wide band performance with minimum noise.
Autoranging selects the most appropriate range within 100ms.
The measurement buffer holds up to 512 readings for fast data acquisition.
Any reading within the buffer may be displayed, or the entire buffer may be searched for the maximum and minimum values.
