The circuit provides a variable offset of typically ±5 V at the signal generator output (Fig. 1).It is powered from the PC’s USB +5-V supply, which is converted by the capacitive voltage ...

Signal generators are a useful piece of kit to have on your electronics bench. The downside is that they tend to be rather expensive. If you have $100 to drop on a new toy, the MHS-5200A is a low c… ...

The circuit on the left can interface with any one of those, plus any 5V logic signal if a dc voltage of 5, 12 or 24V is also available. 16mA has been chosen for the led current to match the drive ...
