To address this need, Agilent’s FieldFox family of RF and microwave analyzers makes it possible to make precise measurements under non-ideal conditions: in a hangar during a snowstorm, aboard a ship sailing rough seas, or at a satellite trailer in a sandstorm (Figure 1).
Figure 1. The handheld FieldFox microwave vector network analyzer enables favorable tradeoffs between speed, accuracy and calibration in the field.
When working in the field, reality often dictates the need for a balance between precision and practicality. In the case of vector network analysis, the key tradeoffs are between speed, accuracy and the complexity of the calibration process. This article will focus on analyzer configurations and calibration methods that support high quality vector network measurements in a short amount of time.
