Abstract

Using three vector receivers VHS56, VHS90 and KPG-10 as reference vector receivers, the comparison calibration of vector receivers in the frequency range 5Hz to 10kHz was performed between HAARI, China and VNIIFTRI, Russia . The sensitivities of X, Y and Z channels of three vector receivers were calibrated by free-field reciprocity calibration facilities and vertical standing wave tube comparison calibration facilities of HAARI and VNIIFTRI. The calibration results of two participants were consonant with each other. There was only one frequency points deviation between calibration results and reference values slightly exceeding the reference expand uncertainties in all 174 calibration frequency points, and the deviations at most frequency points were less than ±0.5dB, which tested and verified the correction and reliability of the calibration results of vector receivers given by both participants international calibration facilities.
