Theory of Operation FieldFox Analyzer
Operation in Modes
Operation in Modes
The FieldFox User’s Guide describes the various modes of operation and describes the user interface for
each mode. The following information describes how the hardware is used in the various modes to make
measurements.
There are six basic modes of operation:
• CAT—Cable and Antenna Test
• NA—Network Analyzer
• SA—Spectrum Analyzer
• VVM—Vector Voltmeter
• PM—Power Meter (USB Sensor)
• CPM—Channel Power Meter
CAT, NA, and VVM modes have similar capabilities but are separate modes of operation.
The six basic modes listed above represent how the hardware may be used to make basic measurements.
Additional modes will provide customized user interfaces but will not change how the basic
measurements are performed.
The following table indicates various modes in FieldFox analyzers and the option dependencies. See the
“Service Related User Operations” section of Chapter 8 for more details.
