Keysight (Agilent) N9937A

FieldFox Handheld Microwave Spectrum Analyser, 5 kHz – 18 GHz


 Keysight / Agilent N9937A Handheld Microwave Spectrum Analyser  In microwave, radar, and satellite communications, and commercial microwave backhaul, you may be responsible not only for hardware installation and maintenance, but also over the-air signal quality. The Keysight N9937A spectrum Analyser is optimized to excel in a dynamic spectral environment. You may face measurement challenges such as the need to detect a low-level signal under strong signal conditions (requiring high dynamic range), or close-in small interference signals (requiring excellent phase noise). Superior dynamic range (TOI > +15 dBm), close in phase noise (-111 dBc/Hz at 10 kHz offset), and fast sweep time make these challenging tasks easier. The Keysight N9937A spectrum Analyser also provides a full power measurement suite and complete trace and state control.With the Keysight N9937A FieldFox’s InstAlign capability, internal amplitude alignments occur automatically as environmental conditions change, without any user intervention. This provides unprecedented amplitude accuracy of ± 0.5 dB for spectrum analysis and power measurements. The Keysight N9937A provides a spectrum Analyser IF output with 25 MHz bandwidth. This enables use as a frequency downconverter and digitize the signal using external test equipment like real time scope, or VSA to do deep signal analysis. FieldFox can connect to the 89600 VSA software (Keysight model number 89601B) via Ethernet to a Windows based PC or tablet. Specifications for the Keysight / Agilent N9937A Handheld Microwave Spectrum Analyser Include: See Datasheet for full specifications     

Product specifications of Keysight Agilent N9937A (From Used-Line T&M Specifications)

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.
