![]() ![]() In its various configurations, the signal generator can provide stimulus signals in the form of analog waveforms, pulse patterns, modulation, intentional distortion, noise, and more. The signal generator pairs with an acquisition instrument such as an oscilloscope or spectrum analyzer to create a complete measurement solution. It is a measurement task that requires a complete solution - one that can generate signals as well as make measurements. This is known as margin or limit testing. ![]() To cite another example, engineers must characterize their emerging designs to ensure that the new hardware meets design specifications across the full range of operating conditions and beyond. In order to use an acquisition instrument to measure the behavior of such devices, you must provide a stimulus signal at the input. Inevitably, it becomes necessary to test the amplifier before it is connected to the circuit that feeds it. And, there are many instances in which no such signal is available unless it is externally provided.Ī strain gauge amplifier, for example, does not produce signals it merely increases the power of the signals it receives from a sensor. But these tools can only make a measurement when they are able to acquire a signal of some kind. An acquisition instrument - usually an oscilloscope or logic analyzer - is probably the first thing that comes to mind when you think about making electronic measurements. ![]()
