A voltmeter that is sensitive and reliable enough to measure and report voltages on the nanovolt scale is called a nanovoltmeter. When measuring extremely small resistances or dealing with minute differential voltages, having an instrument that can accomplish this accurately can be quite helpful.
To minimise sources of noise and instability, a complex design process went into creating this instrument. To prevent excessive noise, the analog-to-digital converters must be of high quality and powered by their source. To complete the task, low-noise amplifiers and a variety of specialised subsystems are needed.
The Global Nanovoltmeter market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
In order to reduce noise in low voltage measurements, Keithley has launched the Model 2182A nanovoltmeter. When coupled with Keithley’s recently released models 6220 DC current source and 6221 AC/DC current source, the Model 2182A offers researchers a powerful new set of capabilities.
Users can now perform resistance measurements, pulsed I-V measurements, and differential conductance measurements more quickly and accurately than in the past, often without the use of an expensive lock-in amplifier or AC resistance bridge.
The combination’s capacity to detect resistance while dissipating very little power in the test equipment makes it beneficial for numerous nanotechnology applications (DUT). Major characteristics/benefits In comparison to earlier nanovoltmeters or sensitive DMMs, the Model 2182A can measure low voltages quickly and accurately while minimising DC drift and noise.
The measurement noise is reduced by approximately a factor of two thanks to the new delta mode operation, which alternates nearly three times faster than its predecessor model. Additionally, compared to its predecessor, the new delta mode contains a unique cancellation technique that drastically lowers the effects of fluctuating thermoelectric voltages.
The Model 2182A decreases the impact of AC common-mode currents while providing 110dB noise rejection at line frequency by synchronising to that frequency. The device has two channels for sensing temperature or voltage.
