HF2LI-MF Multi-Frequency

The HF2LI-MF Multi-Frequency option extends the capability of the HF2LI Lock-in Amplifier by adding a wide range of alternative configurations. This greatly improves the flexibility of the instrument.

HF2LI-MF Key Features

  • Signal input switch matrix for all 6 demodulators
  • Arbitrary frequency for all 6 demodulators
  • Oscillator switch matrix
  • Individual demodulator filter settings (slope and time constant)
  • Extended ziControl host control program

HF2LI-MF Upgrade and Compatibility

  • Prerequisite for the HF2LI-MOD option
  • Compatible with all other HF2LI options
  • Field-upgradeable option

HF2LI-MF Applications

  • Semiconductor & Engineering
  • Atomic Force Microscopy (AFM)
  • Sensors and Actuators
  • Materials Science
  • Laser Spectroscopy

HF2LI-MF Functional Diagram

Installing the HF2LI-MF Multi-Frequency option on the HF2LI enables signal analysis at 6 frequencies simultaneously. The independent configuration for each demodulator allows users to choose the function of each demodulator between harmonic frequency, arbitrary frequency analysis, or reference frequency tracking. In this way, a single HF2LI can replace a stack of lock-in amplifiers and simplify experimental setups.
