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 seven basic modes of operation:
— CAT/TDR - Cable and Antenna Test
— NA - Network Analyzer
— SA - Spectrum Analyzer
— VVM - Vector Voltmeter
— PM - Power Meter (USB Sensor)
— CPM - Channel Power Meter
— ERTA - Extended Range Transmission Analysis
CAT, NA, and VVM modes have similar capabilities but are separate modes of
operation.
The 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.
