Connect MFLI with External Signal Generator

on July 26, 2019 at 4:18 pm by Marco Brunner
This blog describes how to use an MFLI lock-in amplifier with an external reference frequency. The reference frequency comes from a signal generator Model 6221 from Keithley which is used to apply higher voltage pulses or sinusoidal signals on the […]

Output Low-Frequency Sinusoidal Signal on the AUX Output of MFLI

  This blog shows how to output sinusoidal signals on the AUX Output with the MD multi-demodulator option. Keep in mind that the AUX output are not designed to output sinusoidal signals as the Signal Output.   Setup 1. On AUX […]

Eddy Current Testing with MFLI Lock-In Amplifier

on August 5, 2015 at 12:07 pm by Marco Brunner
This blog describes a method to detect material defects. Eddy current measurements are used for non-destructive material testing (NDT). An alternating magnetic field is penetrating a sample. The material defect is detected by a phase shift. In the first part […]
