Given the new dynamics of wideband, microwave and millimeter wave communications, Keysight developed the next generation FieldFox Microwave Analyzer with 120 MHz of real-time bandwidth and frequency coverage up to 50 GHz. To address the millimeter wave frequency requirements for 5G, satellite and automotive radar industries, FieldFox can easily extend its frequency up to 110 GHz with an add-on downconverter.
FieldFox is also the industries most integrated handheld analyzer supporting over 20 key RF and microwave instrument functions including signal analyzer, full 2-port vector network analyzer, real-time spectrum analyzer, over-the-air demodulation, CW signal source, power meter and many more, in an all-in-one field proof package.
| Key Features |

| Make accurate spectrum analyzer measurements (± 0.3 dB) without warmup. |
| Capture intermittent signals with 120 MHz gap-free, real-time bandwidth. |
| Characterize radar pulse profiles with a portable solution. |
| Perform over-the-air measurements for 5G NR and LTE. |
| Capture I/Q data for RF signal monitoring and analysis. |
| Use GPS/GNSS for geolocation and timestamping. |
| Carry one lightweight unit at 3.4 kg (7.4 lb). |
| Benefits |
|
| Built For 5G | 5G technologies provide dramatic network speed improvement and superfast connection time.
5G New Radio (NR) is the 3rd Generation Partnership Project (3GPP) standard for the wireless network running on the sub-7.125 GHz frequency band (FR1) and above 24.250 GHz on the millimeter-wave (mmWave) frequency band (FR2). 5G offers gigabit per second data rates.
5G networks use wider bandwidths, higher operating frequencies, and active antenna systems, such as phased array antennas.
The key challenges for 5G network deployment are characterizing air interface path loss, optimizing beam coverage, and mitigating interference issues.
Keysight’s 5G gNodeB (gNB) field test solution, based on the FieldFox microwave analyzer, provides a complete toolkit for radio frequency (RF) engineers and technicians to install and troubleshoot 5G networks.
This solution can verify hardware gNB performance, such as cable and antenna conditions, transmit power, control channel power, and RF spurious responses.
It can also verify signal quality over the air, including multipath synchronization signal information and coverage area path loss, as well as identify and troubleshoot interference issues.
