The 4-channel differential preamplifier.

Supplier: Signal Recovery

Caracteristics

  • 4-channel differential
  • High impedance
  • Real differential inputs

The new Signal Recovery 7210DIF differential preamplifier will allow you to remove mass loops from your experiments and measure floating mass sources (AC Bridge).

The 7210DIF can also be combined with the Signal Recovery synchronous detection amplifiers (more specifically the 7270 multi-channel model) to increase its sensitivity.

Like the entire Signal Recovery range, the 7210DIF features low noise, high impedance inputs and can be powered directly with your Lock-in or via an AC outlet.

Specifications
