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. Fast, high precision, and the built-in control function, make 6220/6221 series be the ideal choice for the following applications, such as hall, Delta mode resistance measurement, pulse measurement, as well as the differential conductance measurement, etc.
