Generator FNIRSI SG-004A

Product detailed description

The FNIRSI SG-004A Multifunction Signal Generator, Thermocouple and Resistance Measurement, 24 V, 0-24 mA, USB-C, is a powerful and versatile instrument for professional and hobby electronics and electrical engineering applications that require a reliable source of various types of signals to test, measure and diagnose electronic circuits.
The generator supports a wide frequency range, allowing signals to be generated from low to very high frequencies. It is ideal for complex testing of both analog and digital circuits. The Signal Generator is the ideal solution for anyone looking for a versatile, accurate and easy-to-use signal source for their electronic projects and experiments. It can also be used for debugging PLC and DCS systems, valve positioner adjustment, inverter detection, etc. and so on.
The device is equipped with an intuitive user interface and a backlit 2.4" colour display that shows all important information, including the currently set parameters and their changes over time in the form of a graph. This facilitates real-time monitoring and analysis of signals.
Its compact size and light weight make this generator the ideal companion for work in the lab, in the field or when visiting clients.
