5. CROSSTALK TEST

Description

This test checks the crosstalks between test ports of the E5071C. The crosstalk is tested by
performing "through" measurements with two test ports connected together and,
short-ended "isolation" measurements with the test ports terminated with N-type "Short"
devices. A "through" calibration is performed to have the through measurement data as the
reference to which the isolation measurement data is compared. With segment sweep
points for a specified frequency range, a swept measurement with the short-ended test ports
is repeated 16 times and the measurement data is averaged. The worst crosstalk value is
determined from the peak value of the average data.
