The design and construction of a simple 10-100MHz noise figure and insertion gain calibrator is described. This instrument, constructed from readily available components, tests the accuracy of Y factor based noise figure measurement and insertion gain to better than 0.2dB over the full dynamic range of the target instrument, (usually ~50dB). The limitations of the method and the corrections applicable at the low end of the gain range are shown. An example of re-adjusting an Eaton 7380 is given.
