Abstract

We propose a compact and low cost waveform source that can be used to calibrate the magnitude and phase response of vector receivers over a bandwidth as large as a few gigahertz. The generator consists of a broadband comb generator followed by a filter and amplifier. The generator's output is calibrated by use of a sampling oscilloscope. As a demonstration, we constructed a source suitable for calibrating vector signal analyzers operating between 43 GHz and 47 GHz. We then used this calibrated source to characterize the response of a commercially available vector signal analyzer over a 120 MHz bandwidth. We compared the result with calibrations performed with multi-sines with different peak-to-average ratios from a more expensive and bulky calibrated source.
