HF2LI Lock-in Amplifier
The Zurich Instruments HF2LI (high-frequency, 2 inputs) is a digital lock-in amplifier covering the frequency range between DC and 50 MHz. It features 2 physical input channels so that it can replace 2 devices in many 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. The computer is connected by a high-speed USB interface, which allows data acquisition at high rates. The HF2LI is delivered with a fully featured graphical user interface and a choice of programming interfaces that greatly add to the usability of the instrument.

HF2LI Available Options
HF2LI-MF Multi-frequency
The HF2LI-MF multi-frequency option impressively extends the capability of the HF2LI lock-in amplifier by adding a wide range of configuration alternatives. This largely improves the flexibility of the instrument and enlarges the research horizon of scientists.
HF2LI-MOD AM/FM Modulation
The HF2LI-MOD is an option for the HF2LI and allows for the direct analysis of sidebands in dynamic AM (amplitude modulation) and FM (frequency modulation) schemes. This option helps the user to precisely measure periodic variations in the frequency or the amplitude of the application signal. Such schemes are typically applied in oscillator and resonator related setups.
HF2LI-PLL Dual Phase-locked Loop
The HF2LI-PLL is an option for the HF2LI and essentially provides a dual programmable digital phase-locked loop which enables fast frequency tracking. Zurich Instruments offers the world's fastest digital PLL, with a unique frequency range of up to 50 MHz using direct sampling technology. In combination with the multi-frequency and the AM/FM modulation options, the HF2LI can be considered as a ground breaking measurement tool for all advanced oscillation applications.
HF2TA Current Amplifier
The HF2TA current amplifier converts 2 input currents into voltage output in a wide frequency range up to 50 MHz. This device is an active probe which can be conveniently placed close to the measurement setup. It supports most applications where a current must be converted to a voltage. The dedicated design of the HF2TA ensures stability and a smooth operation over the entire frequency range.
HF2LI-PID Quad PID Controller
The HF2LI-PID option builds on the HF2LI and seamlessly integrates no less than 4 high performance PID (proportional integral derivative) controllers for general purpose control. The controllers provide the means to efficiently implement closed loop control on several measured physical units.
HF2TA Current Amplifier
The HF2TA current amplifier converts 2 input currents into voltage output in a wide frequency range up to 50 MHz.
