Data for An open-source high frequency lock-in amplifier
Listed in figshare
We present a lock-in amplifier based on a field programmable gate array capable of demodulation at up to 50 MHz.
Description
The system exhibits 90 nV/√Hz of input noise at an optimum demodulation frequency of 500 kHz. The passband has a full-width half-maximum of 2.6 kHz for modulation frequencies above 100 kHz.
Our code is open source and operates on a $300 hardware platform.<br><br>Data used to compare a custom built, FPGA based lock in amplifier at Warwick University. Includes input noise measurements at varying demodulation frequency and measurements of linearity. data in .csv and .mat format.
