Low-cost multi-channel analog sampler and signal generator for remote laboratories

This paper presents a low-cost analog sampler and signal generator for use with remote laboratories in analog electronics. Although the module is developed for close integration with a dedicated platform for simple prototyping of remote laboratories, the module can be used with most experiment setups with little or no extra adaptations. The sampler offer 16 true simultaneous sampling ADCs, without an analog mux, and the signal generator offers 4 simultaneous sampling analog outputs. An FPGA combined with a Raspberry PI is used for control and interface towards the server side of the experiment.
