Abstract
The present disclosure relates to a measurement system comprising a vector analyzer (VNA), at least one remote frontend, and a cable connection connecting the at least one frontend to the VNA. The VNA comprises at least one signal source generating a RF signal and providing the RF signal via the cable connection to the at least one remote frontend. The remote frontend includes at least one measurement port for connecting a device under test (DUT) and transmitting the RF signal to the DUT, and at least one directive element. The at least one directive element couples out a transmitted portion of the RF signal and a reflected portion of the RF signal received at the at least one measurement port for measuring the transmitted portion and the reflected portion of the RF signal. The remote frontend further includes at least one dedicated calibration circuit connected between the at least one directive element and the at least one measurement port. The at least one dedicated calibration circuit provides calibration standards for calibrating the measurement system.
