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
How to Set Up Over–the–Air (OTA) Mode Settings
— Then CC (select component carriers)
— All (Not applicable for Spectrum. When All is specified, for
Spectrum, the FieldFox defaults to CC0) or
— CC0, CC1, CC2, CC3, or CC4 (i.e., 5G TF and 5G NR have
up to eight component carrier choices (
CC5, CC6, and
CC7
))
Repeat process as needed for additional Windows, Data, and CC settings.
8. Select a substep:
a. When Display Type is set to Bar Chart or Strip Chart then for all for
all OTA Options: Press Trace 6
> More
— Then Meas Data n – Then select the data type:
LTE FDD and LTE TDD: RSRP, RSRQ, RSSI, SINR, PSS, SSS
(Default = RSRP).
5G TF: PSS, SSS or Power (Default = PSS).
5G NR: RSRP, RSRQ, RSSI, SINR, PSS, SSS or DMRS
(Default = = RSRP).
5G NR EVM: RSRP, RSRQ, RSSI, PSS, SSS, PBCH, DMRS, or
Power (Default == PSS).
— Then
Sort Order and choose Up or Down (Default == Auto).
Refer to
“About Over–the–Air (OTA) Measurements” on
page 352
. When this softkey is inactive the Sort Order is set
to Auto.
— Then Sort Data n – Then select the type of data to be sorted:
LTE FDD and LTE TDD: RSRP, RSRQ, RSSI, SINR, PSS, SSS,
Freq Error.
5G TF: PSS, SSS, Power, Sync Corr.
5G NR: RSRP, RSRQ, RSSI, SINR, PSS, SSS, DMRS, Freq Error,
SSB Index.
5G NR EVM: RSRP, RSRQ, RSSI, PSS, SSS, PBCH, DMRS,
Power, Sync Error, Time Offset, PSS EVM, SSS EVM, PBCH
EVM, DMRS EVM, Composite EVM.
— Then
Data Logging – to record data. Refer to “How to Use
Data Logging (OTA Options 370, 372, 377, and 378)” on
page 407
.
IMPORTANT! When multiple component carriers are selected, the results
of the component carrier (CC) with the highest power are displayed. Refer
to
Figure 13-17 on page 379.
