1801 Nanovolt Preamp Option
Remote preamp architecture provides extended measurement ranges and improved sensitivity
For 2001 and 2002 DMMs
With just 0.6nV p-p noise, the Model 1801 Nanovolt Preamp for the Model
2001 and 2002 is the most sensitive room temperature digital nanovolt-
meter available. But it's equally suitable for a wide range of low-level AC
voltage, 4-wire ohms, frequency/period, and differential temperature
measurement applications. It extends the low-level measurement ranges
and amplifies the voltage sensitivity of the Model 2001 and 2002 DMMs by
1000 times.
The Model 1801 is specifically designed for connection to these DMMs via
the option slot on the instrument's back panel. The 1801 takes advantage
of the DMM's flexible user interface and measurement and display capabili-
ties, while isolating the preamp from the noisy electrical environment sur-
rounding the test rack.
