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 […]

Protect Setup From High Voltage Peaks

on November 24, 2017 at 11:24 am by Marco Brunner
This blog describes how a setup can be protected from overvoltage which occurs switching off a coil. Fast┬áchanging currents induce transient voltages in an inductive load which can be expressed by the formula: V = – L (dI/dt) L is […]
