MultiPath Vectorial VNA Calibration
MultiPath Vectorial VNA Calibration allows to correct the VNA receivers measurement in multiple DUT's planes. Multiple VNA calibration is available when the VNA and I/O switch instruments are activated in the Setup Editor. Depending on the measurement type and the level of accuracy needed for the measurements, different calibration are possible.
