System-Level Calibration of a Millimeter-Wave Vector Signal Analyzer With Uncertainties

Year: 2025

Type: article

Abstract: We describe the system-level calibration of a vector signal analyzer operating at 28 GHz, including the determination of uncertainties in the magnitude and phase of measurements of a traceably characterized calibration waveform. We then apply the IEEE 1765-2022 measurement comparison approach to evaluate the uncertainty in error vector magnitude of the vector signal analyzer using an equivalent-time sampling oscilloscope with traceable calibration as the reference receiver. An additional measurement of the modulated waveform is made for comparison using a large-signal network analyzer operating on an arbitrary frequency grid, with good agreement to the sampling oscilloscope and vector signal analyzer in amplitude, phase, and error vector magnitude.
