HF2LI Lock-in Amplifier

HF2LI Lock-in Amplifier

The HF2LI is a technology milestone in both the support of existing applications and in the enabling of the development of many new ones.
Technology From: Zurich Instruments

HF2LI Lock-in Amplifier

The HF2LI is an advanced digital lock-in amplifier with an extended signal frequency range of 50 MHz. With its 2 physical input channels, it replaces 2 traditional lock-in amplifiers for measurement setups. The 128-bit digital signal processing delivers superior precision thus boosting both the noise performance and the dynamic reserve. With these unprecedented capabilities, the HF2LI brings lock-in amplification to a new level and enables new applications in a frequency range that was previously tied to analog instrumentation.

Key Features
  • 2 independent lock-in units, 2 signal generators
  • 1 fundamental and 2 harmonic frequencies per lock-in unit
  • 1 µHz - 50 MHz frequency range
  • 210 MSample/s, 14 bit A/D conversion
  • 5 nV/√Hz input voltage noise
  • 1 µs - 500 s time constant
  • 6 to 48 dB/oct filter slope (1st to 8th order)
  • 4x 1 MSample/s, 16 bit, ±10 V auxiliary analog output
  • 2x 400 kSample/s, 16 bit, ±10 V auxiliary analog input
  • USB 2.0 high-speed host connection
  • LabOneĀ® toolset: Scope, Sweeper, Spectrum Analyzer, etc.
Applications
