FieldFox handheld analyzers deliver benchtop-instrument accuracy in field-test environments. Designed for harsh conditions and hard-to-reach locations, FieldFox analyzers cover satellite communications, microwave backhaul, military communications, radar systems and a wide range of additional applications.
FieldFox microwave analyzers can be configured as cable-and-antenna analyzers, spectrum analyzers, vector network analyzers, or all-in-one combination analyzers. Each compact, 6.6-pound (3.0-kg) package is available in four frequencies: 9, 14, 18 or 26.5 GHz.
To ensure durability in harsh field environments, the completely sealed enclosure is compliant with U.S. MIL-PRF-28800F Class 2 requirements. To enhance ease of use, the instrument has a vertical, or "portrait," orientation and large buttons, allowing users to easily operate the unit with their thumbs, even while wearing gloves.
FieldFox microwave spectrum analyzers provide industry-leading amplitude accuracy of ±0.5 dB at power-up, with no warm-up required, allowing field users to instantly and precisely characterize transmitter power. They can detect more signals in the band of interest with phase noise of -111 dBc/Hz at 10 kHz offset, and measure low-level signals in the presence of high-power transmitters with spur-free dynamic range of 105 dB.
The microwave combination analyzer base function is a cable and antenna analyzer and it can be configured to include a spectrum and network analyzer. FieldFox can be ordered with additional capabilities: power meter, independent signal generator, vector voltmeter, interference analyzer, variable DC source, and built-in GPS receiver.
