In FieldFox, these experiences translated into attributes that make it ready for the toughest conditions. To ensure durability in harsh environments, the completely sealed enclosure is compliant with US MIL-PRF-28800F Class 2 requirements. The water-resistant chassis, keypad and case can withstand salty, humid environments and a temperature range of 10 to +55 °C (14 to 131 °F). Gasket-sealed doors protect the instrument interfaces from moisture, and the dust-free design — with no vents or fans in the case — helps extend instrument reliability. The case can also withstand shock and vibration. Finally, a specially designed connector bay protects the RF connectors from damage due to drops or other external impacts.
Defining field-ready ergonomics
First-hand observations of on-the-go personnel provided deeper insights into practical, meaningful decisions about ergonomics. For example, a nonslip rubber grip — built into the case — not only fits securely into the user’s hands, it also prevents the analyzer from sliding off the hood of a vehicle. The front-panel buttons are large enough to easily operate while wearing gloves (Figure 2).
The vertical or “portrait” orientation and 7.4-inch (188 mm) width makes FieldFox easy to hold. Coupling that with a carefully designed keypad layout makes it easy for a user to operate FieldFox with their thumbs. Also, a weight of just 6.6 pounds (3.0 kg) makes FieldFox easier to carry than similar analyzers.
Because FieldFox may be used day or night, inside or outside, we included a bright, low-reflective display and five display modes that optimize viewing under a wide range of lighting conditions. The keys are also backlit
