Installation, Verification, and Maintenance
As high-frequency technologies develop and extend beyond the lab,
the need for portable, high-performance test gear increases. FieldFox
handheld analyzers are able to withstand the toughest RF and microwave
measurement environments regardless of test site location. Install, verify,
and maintain systems in the field using one unit that supports over 25
measurement capabilities.
FieldFox’s software options provide the same precision and accuracy
as the Keysight equipment on your lab bench. You can customize your
configuration at initial purchase or upgrade later with license keys that you
can quickly and easily install in the field. There is no need to send the unit
back to upgrade it.
FieldFox Family Overview

Find us at www.keysight.com
FieldFox offers two series in the product family that differ in frequency
range and bandwidth. The A-Series models have frequency coverage
from 100 kHz to 50 GHz with 10 MHz of bandwidth, while the B-Series
models have frequency coverage from 9 kHz to 54 GHz and up to 120 MHz
of bandwidth. To see a side-by-side comparison of the A-Series versus
B-Series specifications, please see the flyer FieldFox Microwave Analyzers:
B-Series vs. A-Series Specifications.
FieldFox has three base configurations to choose from — vector network
analyzer (VNA), cable and antenna tester (CAT), and signal analyzer (SA).
You can also configure your unit as a combination analyzer that supports all
of the base functions and more. Figure 1 shows a visual representation of
the FieldFox family of instruments.
