Product Features

    DC Current Source and Nanovoltmeter
    Keithley's new Model 6220 DC Current Source delivers the high resolution, low noise, low current sourcing you need to test and characterize today's tiny, fragile electronics. Pairing the 2182A with the 6220 creates a modular source and measure solution that can perform:

    • Delta Mode Measurements — 1000x rejection of offsets
    • Differential Conductance
    Model 6220 DC Precision Current Source
    • Source and sink (programmable load) 100fA to 100mA
    • 1014Ω output impedance ensures stable current sourcing into variable loads
    • 65000-point source memory allows executing comprehensive test current sweeps directly from the current source
    • Built-in RS-232, GPIB, Trigger Link, and digital I/O interfaces
    • Reconfigurable triax output simplifies matching the application's guarding requirements
    • Model 220 emulation mode eliminates need to reprogram existing application
    Model 2182A Nanovoltmeter
    • 1 nV resolution on 10.000000 mV range
    • p-p noise at 1s response time, 40–50nV p-p noise at 60ms
    • Synchronization to line provides 110dB NMRR and minimizes the effect of AC common-mode currents
    • Dual channels support measuring voltage, temperature, or the ratio of an unknown resistance to a reference resistor
    • Thermocouple linearization (8 T/C types) and cold junction compensation
    • GPIB and RS-232 Interface

    The Need for Precision, Low Current Sourcing
    Device testing and characterization for today's very small and power-efficient electronics requires sourcing low current levels, which demands the use of a precision, low current source. Lower stimulus currents produce lower - and harder to measure — voltages across the device. Combining the Model 6220 DC Current Source with a Model 2182A Nanovoltmeter makes it possible to address both of these challenges.

    Differential Conductance
    Differential conductance measurements are among the most important and critical measurements made on non-linear tunneling devices and on low temperature devices. Mathematically, differential conductance is the derivative of a device's I-V curve. The Model 6220 combined with the Model 2182A, is the industry's most complete solution for differential conductance measurements. Together, these instruments are also the fastest solution available, providing 10x the speed and significantly lower noise than other options. Data can be obtained in a single measurement pass, rather than by averaging the result of multiple sweeps, which is both time-consuming and prone to error. The Model 6220 and Model 2182A are also easy to use because the combination can be treated as a single instrument. Their simple connections eliminate the isolation and noise current problems that plague other solutions.
