Model 1801 Nanovolt Preamp (for Model 2001 and 2002)

Part Number: 1801

Key Features and Benefits:
  • <600pV p-p DCV noise
  • 10nV/day voltage stability
  • 1GΩ isolation and 175dB CMRR
  • Rise times from 500μs to 10s
  • Chopper-based design cancels flicker noise
  • Extends low-level measurement ranges and amplifies the voltage sensitivity of the Model 2001 and 2002

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 nanovoltmeter 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.
