Short summary
An intercomparison in the framework of the German Calibration Service (Deutscher Kalibrierdienst – DKD) was carried out. Two different travelling standards were used to measure the rise time of a pulse generator and the rise time, bandwidth and attenuation of an oscilloscope. Fourteen participants performed the measurements from September 2015 until May 2016. The overall results show that the measurements of the participating laboratories are in good agagreement with the reference values.
