Option 377, 5G NR / 5G NR EVM Conducted Option 378
How to Set Up Over–the–Air (OTA) Mode Settings
— And, refer to Figure 13-16 called, “Example of 5G NR Multi-Beam –
Displaying Multiple Beams From Cell Site 378,” on page 363
.
— See also
“GNSS (GPS+) and GPS” on page 795.
2. Selecting OTA mode:
— Press Mode_

(Available modes are Option dependent.)
—
LTE FDD (default) or
—
LTE TDD
— 5G TF
— 5G NR
— 5G NR EVM Conducted
The OTA format chosen begins scanning for signals.
Additional FieldFox setting changes are required for OTA to
display the available signals. Refer to the steps below and
see also,
“How to Define a Cell or Cell(s) and Use OTA” on
page 384
.
4. Define some carrier and cell measurement information. See also,
“How to
Define a Cell or Cell(s) and Use OTA”
.
Then modify the carrier and cells based on the selected OTA technology
(i.e., LTE FDD, LTE TDD, 5G TF, and 5G NR /5G NR EVM Conducted).
5. Press Freq/Dist
If after making the setting changes in the steps below, no data is
displayed, refer to
“Troubleshooting” on page 416.
