Q: The invert (INV) button does not work. Does this function apply to all outputs when used?
A: No. The invert function is available only for the TTL/CMOS output from the generator. To use this, first push the square waveform for the instrument to be in square wave mode. Now you can adjust the duty cycle on the TTL/CMOS output also. Connect a BNC cable to the TTL/CMOS output and push the INV button. Now you will see your signal become inverted.
