Abstract

SSLT (Short-offset-Short-Load-Through) is a classical calibration method of VNA (Vector Network Analyser) which needs multiple assembly of the standard parts and exists the impact of the phase in the millimetre waveband. Aimed that the S11 of the two-port waveguide DUT is less than -10dB, a simple SLT (Short-Load-Through) calibration method is presented in this paper according to the simplified error model. This calibration method only needs to carry on the calibration of short circuit plate and the matching load in the one-port of the VNA, and the through in the dual-port. The calibration process and the correction algorithm is simple. Finally, it is found that the amplitude relative error of the SLT calibration method is less than 2% and the phase calibration error is less than 2.5øthrough the statistics of several DUTs.
