NIST Impulse Spectrum Amplitude Measurement Service



Nicholas Paulter, Donald R. Larson


The NIST service for measuring the impulse spectrum amplitude of the output of impulse generators is described. The calibration procedures used in this measurement service were recently modified and this reduced both the time for measurement and the published uncertainties. Using this new calibration method and associated uncertainty analysis, the published uncertainties for the bandwidth of 10 MHz to 4 GHz have been reduced from ' 0.5 dB to less than ' 0.1 dB for the parameter of impulse spectrum amplitude. Furthermore, the new calibration method allows this NIST measurement service to be extended to higher frequencies to support the measurement of the spectrum amplitude of ultra-wideband (UWB) signals.
