For millimeter-wave (mmWave) signal analysis, Keysight Technologies has extended the frequency range of its FieldFox handheld signal analyzers to up to 170 GHz. Keysight’s A- and B-Series FieldFox handheld analyzers with a frequency of 18 GHz or above can be used with VDI PSAX frequency extenders to cover the sub-THz frequency range thanks to a partnership with Virginia Diodes Inc. (VDI).
For the advancement of contemporary wireless communications and radar systems, field-based engineers require accurate mmWave measurements. For 5G, 6G, aerospace, defense, and automotive radar transmission/receiving testing, this is crucial.
Nevertheless, mmWave communications are extremely susceptible to interference, weather, and obstructions.
Engineers can design more effective networks and radar systems, increasing coverage and reliability, by precisely measuring their propagation properties.
Large desktop signal analyzers and generators, which are frequently highly costly and unwieldy for field measurement use cases, are typical examples of older equipment used to obtain this knowledge.
When used in conjunction with VDI’s PSAX frequency extension modules, the Keysight FieldFox solves this problem and makes mmWave measurements possible in a portable, lightweight device.
To provide a mmWave signal generation solution up to 170 GHz, engineers can alternatively choose the FieldFox with the downloadable Option 357 pulse generator, which can be combined with a VDI PSGX module. This gives consumers a straightforward, user-friendly, and durable way to get precise mmWave measurements.
When paired with VDI frequency extender modules, Keysight’s FieldFox offers the following main advantages:
- Expanded frequency coverage: Expanding the FieldFox’s frequency coverage from as low as 18 GHz, depending on models, up to 170 GHz for either signal analysis or generation.
- Optimized performance at the mmWave range: Supporting in-band signal analysis with selection of spectrum analyzer mode, IQ analyzer mode, or real-time spectrum analyzer (RTSA) mode with extraordinary sensitivity of -155 dBm/Hz typical value.
- Cost efficiency: Compared to traditional mmWave signal analysis and generation solutions, the combination of Keysight FieldFox and VDI frequency extenders reduces costs by half or more.
- Portable and convenient testing: Weighing approximately less than 4 kg in total, the combination of Keysight FieldFox and VDI frequency extenders makes the mmWave field testing much more feasible and convenient for both field and lab environment.
Key Comments
Dr. Thomas W. Crowe, CEO of VDI, said: “VDI manufactures state-of-the-art test and measurement equipment for mmWave and THz applications, including vector network analyzer, spectrum analyzer, and signal generator extension modules. These products enhance the capabilities of high-performance microwave measurement tools by extending them to higher frequencies. Through our collaboration with Keysight, VDI is excited to provide frequency extenders for the FieldFox handheld analyzers, offering customers lightweight solutions for both signal analysis and generation in the mmWave range, with exceptional signal quality and measurement integrity.”
Vince Nguyen, Vice President and General Manager, Aerospace, Defense, and Government Solution Group at Keysight, said: “The aerospace, defense, and commercial sectors lack a portable solution which can provide accurate mmWave measurements. As customers explore innovations they need access to higher frequencies in the radio spectrum, including mmWave. Working with VDI, we’ve developed a solution that is easy to test signal analysis and generation in the field as well as in the laboratory.”
Keysight’s FieldFox combined with VDI extenders will be showcased for the first time at the Keysight booth (Hall A3, Stand 506) at electronica 2024, the world’s leading trade fair and conference for electronics, from November 12 to 15, 2024.
