The GOM-802+S232C+GPIB is a combination of three GW INSTEK instruments. The GOM-802 is a combination digital RMS multimeter and digital oscilloscope. It has an 8-bit resolution and can measure AC, DC, and true RMS voltage, current, frequency, and resistance signals with a basic accuracy of 0.05%. The S232C is a digital signal source that offers dual output, balance and unbalance signal output as well as sine, staircase, and triangle waveforms with 32-bit accuracy. The GPIB is an interface that allows for communication between the two instruments, allowing them to be controlled and data to be collected using the most up-to-date protocols. The GOM-802+S232C+GPIB combination gives users a comprehensive and versatile test capability that meets the demands of modern test and measurement applications.
