Description
Field RF work rarely happens next to a bench. So the Keysight N9918B FieldFox analyzer packs cable, antenna and VNA functions up to 26.5 GHz into a rugged handheld combination unit. Lost in HCM also lists it for rental and sale, with service on request.
One handheld for cable, antenna and spectrum work
First, cable and antenna test, vector network analysis and spectrum modes share a single case. So a crew can check a feeder, then sweep the band, without swapping instruments. Options add real-time spectrum, interference and over-the-air measurements, plus GPS/GNSS, remote control and data capture.
| Frequency range | 30 kHz to 26.5 GHz for CAT/VNA functions |
|---|---|
| Real-time bandwidth | Up to 120 MHz, option dependent |
| S-parameter dynamic range | Up to 115 dB, configuration dependent |
| Weight | Approximately 3.4 kg |
| Power | Rechargeable battery or AC adapter |
Carry it, charge it, check it
The rugged, battery-powered design targets field maintenance. At about 3.4 kg it also travels easily, while an AC adapter covers long sessions at a site office. However, the installed options decide which functions a unit has, so confirm them before the trip.
Field jobs for the Keysight N9918B FieldFox analyzer
- Base-station cable and antenna maintenance, such as feeder checks.
- Satellite and microwave-link commissioning, such as link checks.
- Interference hunting.
- Field verification of RF components and networks.
Crews also compare it with the Rohde & Schwarz Spectrum Rider and ZNH and with Tektronix RSA handheld workflows. Then check analyzer modes, frequency range, VNA ports, tracking source, real-time bandwidth, battery life and weather protection.
Accessories to list with the quote
A handheld is only as good as its kit, so name the calibration kit, test cables, adapters, antennas, GPS and carrying accessories. Then request a quote from Lost in HCM for the Keysight N9918B FieldFox analyzer, with your dates and delivery site. The spectrum and signal analyzers range shows related models. You can also contact SMK Vietnam for help choosing options. The Keysight website holds official product data.
