Shared Hardware and Field Usability
Most FieldFox models, including the N9912A, N9914A, N9917A, N9918A, and N9923A, share a standardized form factor measuring 292 x 188 x 72 mm and weighing between 2.7 kg and 3.0 kg. The N9952A has slightly different dimensions at 188 x 292 x 82 mm. All models feature a 6.5-inch transflective VGA color display designed for visibility in outdoor environments, backed by an LED backlight. They are built to function in an operating temperature range of -10 to 55 degrees Celsius and run on external DC power (typically 15 to 19 VDC) via an AC/DC adapter or internal Lithium-ion battery power. Physical interfaces across the series generally include dual USB 2.0 Host (Type-A) ports, a mini-B (or mini-USB) Device port, and a LAN port.
Analysis Capabilities and Frequency Ranges
The family is divided into RF analyzers, dedicated network analyzers, and high-frequency microwave combination analyzers. The N9912A is an RF analyzer configurable with spectrum analysis options up to 4 GHz (Option 230) or 6 GHz (Option 231), or CAT analysis from 2 MHz to 4 GHz (Option 104) or 6 GHz (Option 106). The N9923A is a dedicated RF Vector Network Analyzer operating from 2 MHz to either 4 GHz or 6 GHz, supporting standard T/R measurements or full 2-port S-parameters with Option 122. For higher frequency work, the combination analyzers start with a base Cable and Antenna Analyzer (CAT) mode and can be configured with VNA and SA capabilities. The N9914A spans up to 6.5 GHz, the N9917A operates up to 18 GHz, and the N9918A reaches 26.5 GHz. For high-frequency applications, the N9952A provides coverage up to 50 GHz for CAT, VNA, and spectrum analysis, utilizing 2.4 mm male test port connectors.
Accessories and Interconnects
The N9910X family comprises option-coded accessories specifically designed to complement the FieldFox handheld analyzers. This family covers RF coaxial interconnects, passive RF components (such as adapters, attenuators, and terminations), calibration kits/standards, and mechanical carrying items. Cables available under the N9910X options include phase-stable and general-purpose 50-ohm coaxial cables of various lengths, which are essential for maintaining amplitude and phase stability during field measurements.
Frequently asked questions
- What are the base measurement modes for the microwave combination analyzers?
- The N9917A and N9918A use Cable and Antenna Analysis (CAT) as their base function, which supports measurements like distance-to-fault (DTF), return loss, and cable loss. Other modes like VNA, Spectrum Analyzer, and Vector Voltmeter are added via configuration options.
- What connector types are used on the 50 GHz N9952A?
- The N9952A is equipped with 2.4 mm (male) test port connectors for Port 1 and Port 2, alongside SMA (female) connectors for external reference input and external trigger input.
