Pulsed signal device characterization employing adaptive nulling and IF gating |
摘要 |
A receiver channel, test system and method employ adaptive nulling to filter a targeted frequency component from a pulsed signal to produce a filtered pulsed signal. The filtered pulsed signal facilitates measuring pulsed performance parameters of a device under test. The receiver channel includes an adaptive nulling filter having a frequency response with a null that is adjustable in a null location to correspond to a vicinity of the targeted component. The test system includes a pulsed signal source, a test set, and a controller that controls the signal source and the test set. The test set includes the receiver channel with the adaptive nulling filter. The method of adaptive null filtering includes adjusting a location of a null in a frequency response of the adaptive nulling filter to correspond to a vicinity of the targeted component to produce the filtered pulsed signal.
