Keysight N9912CU/378 - Over-the-Air (OTA) 5G NR Option for N9912C
The Keysight N9912CU/378 is the Over-the-Air (OTA) 5G NR option for the N9912C.
This option requires an instrument with the spectrum analysis function enabled. It also requires the options below (sold separately):
- N9912CU/307 (GPS receiver)
- N9912CU/B04 (Bandwidth, 40 MHz)
Option N9912CU/235 (pre-amplifier) is recommended, but not required.
OTA analysis frequency range
The testing frequency range is dependent on the spectrum analysis option installed on the N9912C.
- N9912C with SA4 - 1 MHz to 4 GHz
- N9912C with SA6 - 1 MHz to 6.5 GHz
- N9912C with SAX - 1 MHz to 10 GHz
Information on testing options
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 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.
