| Abstract: | We introduce a method for 50 GHz comb generator calibration using Agilent 86100 C sampling oscilloscope. The 70 GHz sampling head measures the output time-domain signal of the comb generator. Then we correct the signal for time base error, including time base distortion, jitter and drift. By transforming the time-domain signal into frequency-domain, we obtain the amplitude and phase spec-trum. Then we acquire the calibration data we need. We also determine the uncertainties of the amplitude and the phase, which are less than 0. 5 dB and 0. 9o respectively. |
