(Excludes localized spurious responses and crosstalk)

System dynamic range is measured as the difference between maximum port power and the RMS noise floor in a 10 Hz bandwidth and no averaging (ports terminated).

Noise floor is calculated as the difference between maximum rated port power and system dynamic range. Receiver Dynamic Range is calculated as the difference between the receiver compression level and the

noise floor at Ports 1 or 2. Normalizing measurement made with a through line connection, with its effects compensated for. The

cables between the VNA and the 3743A modules are assumed to be the 806-206 1.85 mm cable (61 cm, 24 in long) or the 806-209 1.85 mm cable (91 cm, 36 in long). All figures are typical.

The graphs give measurement uncertainties after the above calibration. The errors are worst case contribution of residual directivity, load and source match, frequency response and isolation, network analyzer dynamic accuracy, and connector repeatability while noise effects are added on an RSS basis. 10 Hz IF Bandwidth is used. For transmission uncertainties, it is assumed that s11 = s22 = 0. For reflection uncertainties, it is assumed that s21 = s12 = 0.
