13 Over–the–Air Measurements (OTA) – LTE FDD Option
370, LTE TDD Option 371, 5G TF Option 377, 5G NR /
5G NR EVM Conducted Option 378
OTA mode measures signals at the SA RF Input Port 2 connector.
OTA mode requires the FieldFox to have SA mode (Option 233 on combination
analyzers), GPS (Option 307), and CPU2 installed.
5G NR requires 100 MHz wide path Option B10.
Recommended, but not required:
— Preamplifier (Option 235) to improve receiver sensitivity.
— EMF (Option 358) to measure the EMF levels of 5G signals.
With
Options 370 (LTE FDD), LTE TDD (Option 371), 5G TF (Option 377), and
5G NR (Option 378) network designers can ensure that networks have enough
resources to carry out handovers (re-selection) when users move between cell
towers on the same 5G network as well as in between 5G and 4G networks
(intra/inter-radio access technology).
The FieldFox OTA measurements support LTE FDD (Option 370), LTE TDD
(Option 371), Verizon 5G TF (Option 377), and 5G NR (Option 378) over-the-air
demodulation for single or multiple component carriers (CCs) and multiple cell
towers for each CC. Additionally, 5G NR EVM Conducted provides EVM
measurement capabilities for conducted signals. The FieldFox display can be
configured to show data formats such as table, bar chart, spectrum and strip
chart of key performance e indicators (KPI's).
By integrating over-the-air (OTA) measurements with cable and antenna test
(CAT), full 2-port vector network analysis, spectrum analysis, and real-time
spectrum analysis (RTSA), the FieldFox can be used for base station setup and
verification.
Some examples in this chapter include the electromagnetic field (EMF)
mode. EMF requires Option 358. See also,

Analyzer) Mode (Option 233–Mixed Analyzers)FUTURE”
