If there was a singular piece of test equipment that is absolutely vital, it would have to be a great DC power supply. This humble little box was the topic of a recent “Ultimate Guide to DC Power Supplies” post we did. At the end of that post, there were a handful of top DC power supply options that are extremely powerful. Given the importance and sheer range of options we wanted to do a dedicated list post to cover a broader set of DC power supply options.

To that end, we compiled a list of 21 great DC power supply options below.

One common piece of test equipment in any RF laboratory is the signal generator. The purpose of these devices is in the name itself “signal generator,” in that it generates signals with tunable properties such as amplitude, frequency, and wave shape. Signal generators are also called function generators, although, function generators often have more advanced features.

Signal generators are most commonly used to test the response of circuits using known and controllable input signal. In order to validate the output signal coming from the function generator it is common to validate that signal with an oscilloscope (but that’s the topic of a future post).
