LCRmeter is a simple to use GUI for common LCR meters, using a PC to control the LCR meter using GPIB, USB or RS232.
It allows sweeping of frequency, AC signal level or DC bias while measuring values. Results can be plotted on a chart and the image saved as PNG or JPG, or they can be dumped to a file in csv format.
It currently supports Tonghui TH2830, 2832, 2827A, 2827C and Keysight E4980A LCR meters. Others can be added that have a similar SCPI command syntax.
LCRmeter is available on Windows 64 bit as a free download here.
