NF Corp LI5502 Lock-in Amplifier Module 10 mHz to 1 MHz, dual phase, 2 channels
A Lock-in amplifier with high reliability for minute signal measurement.
Its main core parts are condensed into a compact chassis.
A significant improvement with the SN ratio can be expected by incorporating this module into the signal detection part of analysis equipment or inspection devices. It is simple design with eliminated both display and operation panel, controlled from a PC via USB/LAN.

NF Corp LI5502 Lock-in Amplifier Module 10 mHz to 1 MHz, dual phase, 2 channels

    • Wide frequency bandwidth 10 mHz to 1 MHz

      It covers a wide frequency range such as mechanical vibration and physical property measurement. Locks to the reference signal in 2 cycles when shortest.

    • High sensitivity 10 nVrms

      Sensitivity can be selected from 10 nVrms to 1 Vrms. It has a wide input voltage range and can measure various signals.

    • High-speed response, time constant from 1 µs

      Equipped with time constant filter and moving average filter. By combining with a moving average filter, high-speed response can be expected even at low frequency.

    • Dynamic reserve 100 dB

      Dynamic reserve is the ratio of acceptable noise level to the signal measurement range full scale. Using this device, you can detect very small signals compared to the noise level.

    • Oscillator output

      Equipped with an oscillator output, the system configuration can be simplified by using it as a reference signal. Output waveform can be selected sine wave or TTL level square wave. DC bias can be added with the output voltage at sine wave.

    • Harmonic measurement

      Measurement is possible not only at harmonics but also at frequencies that are fractional multiples of the fundamental (×1/1 to ×63/64).
      It also supports advanced measurements such as second derivative.

    • 2-channel model (LI5502)

      The LI5502 is two channels of input model so simultaneously measures the two signals with the same reference signal.
      Amplitude ratio and phase difference between channels can also be measured.

    • USB/LAN interface

  • Please allow 2 - 3 weeks lead time for this new product to arrive.

    Comes with a 1 year warranty from the manufacturer.
