Radio frequency testing apparatus with voltage standing wave ratio adjustment and corresponding method

Abstract

A radio frequency testing apparatus with voltage standing wave ratio adjustment for testing a device under test is provided. Said radio frequency testing apparatus comprises an input, an output, a signal source for providing a test signal for the device under test via the output, thereby forming an output signal path, a signal sink for receiving a received signal from the device under test via the input, thereby forming an input signal path, and a tracking generator. In this context, the tracking generator and/or the signal sink is configured to determine a corresponding voltage standing wave ratio at the input and/or at the output. Furthermore, the signal source is configured to pre-equalize the test signal on the basis of the corresponding voltage standing wave ratio at the output and/or the input. In addition to this or as an alternative, the signal sink is configured to post-correct the received signal on the basis of the corresponding voltage standing wave ratio at the input and/or the output.
