Project to build a LCR meter
The LCR meter I built and described in previous posts has some issues. In this post I’ll describe how I tried to solve them. Observed Issues Looking at the test…
In this post I am going to talk about revision 2 of the PCB and show some test results. PCB Revision 2 Revision 2 of the…
In this post I am going to explain some features of the device's firmware. Firmware The LCRH7…
Based on the ideas developed so far I built a prototype. …
In this part I am are going to take a dive into LCR measurement theory and finally derive formulas for computing measurement results and we will find a way to…
In this part I am exploring a way to implement the filters for the lock-in amplifiers of the meter.Trying to design a low pass FIR filter with one of the…
I continue with the design of the LCR meter, draw a simplified schematic of the box and design the C-code for a DDS generator we can use for hardware and…
Is it possible to build an LCR meter without an FPGA or any fancy DACs, ADCs and DDS chips for signal generation, just using the analog capabilities of the MCU,…
