Variable Voltage Injector

When testing circuits and fault finding there is often a need to inject a defined DC voltage level at some point on the circuit. It may, for example be necessary to apply a logic level on the input of a digital gate or a reference voltage level on the input of an analogue circuit. With this handy piece of kit you can select one of five fixed voltage levels of 0 V, 2.5 V, 3.3 V, 4.096 V or 5 V. In addition the output can supply a variable voltage in the range of 2.9 V to 7.3 V adjustable via a pot.
