数字万用表 Picoammeter Voltage Source
The 5-1/2 digit Model 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:**
* 10fA resolution
* 5-1/2 digit resolution
* * Alternating Voltage method ohms measurements
* Automated voltage sweeps for I-V characterization
* Floating measurements up to 500V
* Up to 1000 readings/second
* Built-in Model 486 and 487 emulation mode
* IEEE-488 and RS-232 interfaces
* Analog output
* Digital I/O
