Frequently Asked Questions - FieldFox Handheld RF Analyzers
What is FieldFox?
FieldFox is the industry's first 50 GHz handheld RF analyzer. The Swiss army knife of electrical measurement, FieldFox functions as a vector network analyzer (VNA), cable and antenna analyzer (CAT), spectrum analyzer (SA), signal generator, or an all-in-one combination RF analyzer.
What is an RF analyzer?
An RF analyzer is a test instrument capable of combining vector network analysis, spectrum analysis, and cable and antenna testing of radio frequency signals. Network analysis characterizes the response of a device or circuit to RF signals, while spectrum analysis measures the frequency, power, and noise of a signal. Analyzers treat the device under test (DUT) as an electrical network to measure how the DUT alters radio frequency signals through interaction.
RF analyzers provide spectrum and network analysis on RF devices and the characterization of parameters such as:
- RF signal amplitude at different frequencies
- scattering parameters (S-parameters)
- impedance of the overall network
- gain in RF signal power
- return and insertion losses
- signal phase shifts
Why choose a FieldFox handheld analyzer?
FieldFox provides benchtop accuracy in a portable package. Built to withstand your toughest working environments, FieldFox is rugged enough to meet MIL specs and enables 5G, satellite, and radar operators to make true RF coverage measurements up to 54 GHz and beyond. Lightweight, rugged, and portable, FieldFox is ready to meet your RF test needs. For more information on the world’s most integrated handheld analyzer, see our technical overview.
What are the benefits of using a handheld network analyzer?
Network analyzers verify the performance of various components such as antennas, amplifiers, cables, and many other active or passive devices. Network analyzers tend to be sensitive equipment, but many network measurements involve devices that live outside the laboratory. Because of this, having a handheld analyzer to carry with you into the field is extremely valuable.
Does FieldFox function as a general-purpose RF analyzer?
Yes, you can configure FieldFox as a cable and antenna analyzer (CAT), vector network analyzer (VNA), spectrum analyzer (SA), signal generator, or an all-in-one combination RF analyzer. With the FieldFox, you can make 5G field test measurements with wide analysis bandwidth up to 120 MHz.
What network analyzer functions does a FieldFox perform?
The key network analyzer functions of FieldFox are pulse measurements, TDR (Time Domain Reflectometry), cable measurements, QuickCal, and full 2-port S-parameters.
What are essential 5G field tests?
There are six essential field tests for 5G networks. These include (1) path loss characterization; (2) base station coverage testing; (3) component carrier power measurements; (4) over-the-air control channel coverage testing; (5) network quality and beam performance verification; and (6) EMF exposure evaluation. To learn more about using FieldFox to perform 5G field testing, check out our eBook: Essential 5G Field Tests or view this short course: How to test 5G networks in the field.
