FieldFox Analyzer Software and System Features

Remote control capability with iPad and iPhone

Engineers and technicians can now remotely monitor and control their FieldFox using their iOS device such as an iPhone, iPad, or iPod Touch. FieldFox’s Remote Viewer iOS app emulates the front panel of the unit, letting you simply press any FieldFox key right from your iOS device. The app also allows you to instantly access technical documents such as data sheets.

FieldFox’s Data Link software makes report generation and documentation easier

FieldFox’s complimentary Data Link software provides data transfer, data definition and report generation. You can add markers and limit lines to traces, and you can load cable files and antenna factors using Data Link.

Remote control via LAN and FieldFox programming

All FieldFox models can be controlled using SCPI over LAN and USB.

Built-in variable voltage DC bias

FieldFox has a built-in variable voltage DC bias source. The DC bias source can provide DC power to amplifiers under test and bias tower mounted amplifiers (TMA) when you need to sweep through the TMA to reach the antenna (bias tees available separately).

Built-in GNSS/GPS

A built-in GNSS/GPS receiver provides geo- location tags to measurements. The geo data-time, latitude, longitude, and elevation-can be displayed and saved in data files. In addition to location information, the GPS provides an external reference to improve FieldFox frequency accuracy.

USB keyboard and mouse support

FieldFox supports use of USB keyboards and mice to simplify the input of text such as file names while working in the field.
