The type 6220 dc current source and type 6221 ac and dc current sources combine ease of use with extremely low current noise. In test environments, from research and development to production, especially in semiconductors, nanotechnology and superconductors, low current sources are critical to applications. The type 6220 and type 6221 have high precision source and built-in control functions and are very suitable for hall measurement and resistance measurement using incremental mode, pulse measurement and differential conductance measurement.
Main features and advantages
The source and resident current ranges from 100fA to 100mA
1014 Ω output impedance to ensure stable current source can provide all kinds of load
The source storage capacity of 65000 points can perform a comprehensive test current scan directly from the current source
Built-in rs-232, GPIB, trigger link and digital I/O interface
Configurable three-axis output interface for convenient application with protection function
Can simulate the early type 220 current source, no need to rewrite the program code for existing applications
The type 6220 dc current source and type 6221 ac/dc current source series are very easy to use precision micro current sources with very low noise. The generation of microcurrent is a key instrument in many research and development and product measurement applications, especially in semiconductors, nanotechnology and superconductivity.
