Product Description:
The Type 6221 AC and DC current sources combine ease of use with extremely low current noise. Low current sources are critical for applications in test environments from research and development to production, especially in the semiconductor, nanotechnology and superconductor industries. High source accuracy and built-in control make the Model 6221 ideal for applications such as Hall measurement, resistance measurement using incremental mode, pulse measurement and differential conductance measurement.
Features:
Ac and DC current sources
Source and drain (programmable load) 100fA to 100mA
1014? The output impedance ensures a stable current source flowing into the variable load
The 65000 point source memory allows full test current scanning directly from the current source
Built-in RS-232, GPIB, trigger link and digital I/O interface
Reconfigurable triaxial outputs simplify the matching of application protection requirements
The Model 220 emulation mode does not require reprogramming existing applications
Instrument control software is available for Macintosh and PC controllers
Provides AC currents from 1pA to 100mA for AC characterization of components and materials.
The 6221's 10MHz output update rate produces smooth sine waves up to 100kHz
Built-in standard and arbitrary waveform generators with frequencies ranging from 1mHz to 100kHz. Applications include use as a complex programmable load or sensor signal and noise simulation
Programmable pulse widths as short as 5µs limit power consumption of precision components. When used with a 2182A nanovolt meter, pulse IV measurements down to 50µs are supported
Built-in Ethernet interface for easy remote control without GPIB controller card
