Microwave measurement accuracy summary Microwave measurement accuracy for the 8703A analyzer is presented in the following graphs and tables. All data is taken after an 8703A accuracy enhancement using the calibration type shown. This analysis accounts for the following errors33: • Residual systematic errors (Table 7) • System dynamic accuracy (dB from reference)34 • 3.
Distance-time domain performance summary Introduction Lowpass step response42: Analog and digital device design, testing and trouble shooting are made easier by using both the distance-time domain and frequency domain capabilities of the 8703A. This combination lets the user: 1) Discover if a problem exists. 2) Locate and quantify potential causes of the problem (i.e. unexpected reflections, attenuations, etc.
Distance-time domain performance summary cont'd Frequency bandwidth (GHz) Measurement description 0.13 to 12.0 0.
General information Group delay measurements Microwave measurement calibration types Group delay is computed by measuring the phase change within a specified frequency aperture (determined by the frequency span and the number of points per sweep). The phase change, in degrees, is then divided by the frequency aperture, in Hz (times –360). Frequency response: Simultaneously corrects for magnitude and phase frequency response errors for either reflection or transmission measurements.
