TD-LTE Signal Analyzer 6-7 TD-LTE Summary
3GPP MG PN: 10580-00234 Rev. T 6-23
6-7 TD-LTE Summary
The following parameters are displayed in the TD-LTE summary measurement.
Freq Error
Frequency error is the difference between the received center frequency and the specified
center frequency. This value is linked to the external frequency reference accuracy and is
typically useful only with a good external frequency reference or GPS reference.
Occupied BW
The measured occupied bandwidth is calculated as the bandwidth containing 99% of the total
integrated power within the selected span around the selected center frequency.
Carrier Frequency
Carrier Frequency is the measured transmitter operating center frequency.
Channel Power
Channel power measures the average power within the selected bandwidth and is expressed
in dBm.
Ref Signal (RS) Power
Reference Signal power displayed in dBm or Watts. The reference signal is used for downlink
channel estimation.
Sync Signal (SS) Power
Sync signal power displayed in dBm or Watts.
EVM (rms)
The RMS (%) of all the error vectors, between the reconstructed ideal signals and the received
signals, divided by the RMS value of the ideal signals.
PBCH Power
Physical Broadcast Channel Power. This physical channel carries system information for user
equipment (UE) requiring access to the network.
PCFICH Power
Physical Control Format Indicator Channel Power. This channel provides information to
enable the UE to decode the PDSCH (Physical Downlink Shared Channel).
Spectral Emission Mask
Displays a Pass/Fail status for the signal measured against the selected mask.
