50 GHz hand-held combination analyser, from Keysight

September 03, 2015 // By Graham Prophet
Keysight Technologies has added six millimeter-wave models to its family of FieldFox handheld analysers, including what the company claims is the first handheld combination analyser to provide coverage to 50 GHz.

With more built-in capabilities than similar analysers, FieldFox can replace three or four single-function instruments — benchtop or handheld — that are typically used for maintenance and troubleshooting of systems that operate at or above Ka-band frequencies. "At only 3.2 kg, [these] FieldFox models deliver laboratory-grade measurements that enable field personnel to fully characterise today’s most demanding radar and satellite systems," said Dan Dunn, general manager for RF and microwave handheld analysers. "...a FieldFox combination analyser provides unprecedented functionality and value at about half the cost of each equivalent benchtop instrument."

Three combination-analyser models cover 32, 44 or 50 GHz and provide spectrum analysis, vector network analysis and cable and antenna testing in a rugged, portable unit. The three spectrum analyzer models cover the same frequency range. In all six new models, spectrum measurements are up to eight times faster than those made with comparable analysers. FieldFox millimeter-wave analysers are also around 1.5 kg lighter than similar units from other vendors. The FieldFox family is optimised for field testing. The fully sealed enclosure — no fans or vents — is compliant with US MIL-PRF-28800F Class 2 standards and is also type tested to meet MIL-STD-810G requirements for operation in explosive environments (Method 511.5, Procedure 1). FieldFox analysers are also type tested to meet IEC/EN 60529 IP53 requirements for protection from dust and water. The analysersare software upgradeable, enabling users to choose the capabilities they need initially and add others later. Examples include vector voltmeter, TDR cable measurements, built-in power meter, pulse measurements, spectrum analyser time gating, interference analyser (with spectrogram), and GPS receiver. The six models are:

N9950A 32 GHz FieldFox microwave (combination) analyser; N9951A 44 GHz FieldFox microwave (combination) analyser; N9952A 50 GHz FieldFox microwave (combination) analyser; N9960A 32 GHz FieldFox spectrum analyser; N9961A 44 GHz FieldFox spectrum analyser; N9962A 50 GHz FieldFox spectrum analyser . Pricing starts at $28,000 for the N9950A.
