I want to connect my computer to 33250A function generator. I installed keysight IO suite and connect my computer and function generator using a usb-GPIB cable. I set the IO port of 33250A as GPIB and set the address 10. In the keysight IO GUI, I also set the GPIB address as 10, and then press the scan button, but nothing is detected. I don't know why, can anyone help me?
