Over–the–Air Measurements (OTA) – LTE FDD Option 370 and 5GTF Option 377 (CPU2
Only)
About Over–the–Air (OTA) Measurements
About Over–the–Air (OTA) Measurements
OTA mode supports these standards:
—LTE FDD and
—5GTF measurements
Some measurement parameters are auto-coupled and are not user-settable.
LTE FDD Features (Option 370)
LTE FDD has the following features:
Cell Scan Results:
— Center frequency
— Physical Cell Information (PCI) – (Cell ID) – (C/S/G)
— RSRP (Reference Signal Received Power) (dBm)
— RSRQ (Reference Signal Received Quality) (dB)
— RSSI (Reference Signal Strength Indicator) (dBm)
— PSS (Primary Synchronization Signal) (dBm)
— SSS (Secondary Synchronization Signal) (dBm)
— SINR (Signal to Interference & Noise Ratio) (dB)
— Frequency error (Hz)
Data Formats:
User can set up and display 1, 2, 3 or 4 simultaneous measurements of key
performance indicators (KPI's) for any component carrier (CC0 through CC4),
up to 5 carriers, in any combination of the following:
— Table – Cell scan numeric results (for up to 6 cell sites (CCs) including
Physical Channel Information (PCI) – (Cell ID), RSRP, RSRQ, RSSI, PSS,
SSS, SINR, Freq Err.
— Bar Chart – Vertical power bar graph of selectable cell scan result metric
for up to 6 cell sites with adjustable color "heat" amplitude scale
— Spectrum – Magnitude spectrum frequency domain (fixed span). You can
only view a single component carrier at a time with Spectrum (e.g., CC0 or
CC2, etcetera).
IMPORTANT! LTE FDD and 5GTF only demodulate PSS and SSS signals
using the FieldFox’s 10 MHz demodulation path. User data channels are
not demodulated.
