1. A system for generating and measuring electrical signals, the system comprising:
a digital-to-analog converter module configured to generate two or more analog signals based on a control signal;
two or more channels, each channel comprising:
an output terminal configured to be electrically connected to an electrical device; and
a buffer circuit configured to receive an analog signal of the two or more analog signals and to provide to the output terminal a voltage based on the voltage of the received analog signal, and further configured to be electrically connected to a current source and to allow current to flow between the current source and the output terminal;
a voltage measurement system configured to measure, for each channel, a voltage indicative of the voltage at the output terminal of the channel; and
a current measurement system configured to measure, for each channel, the current flowing through the output terminal of the channel;
wherein the digital-to-analog converter module is a voltage source digital-to-analog converter module configured to control the voltage of the two or more analog signals based on the control signal and on a voltage received from a power supply;
wherein the voltage measurement system comprises a voltage-measurement analog-to-digital converter module configured to:
receive, from each channel, an analog voltage indicative of the voltage at the output terminal of the channel; and
generate, for each channel, a voltage measurement signal representing the analog voltage received from the channel, wherein the voltage measurement signal is a digital signal,
wherein the voltage-measurement analog-to-digital converter module is electrically connected to each channel through a voltage divider.
