TD-LTE Signal Analyzer
6-5 TD-LTE Over-the-Air (OTA) Measurements
3GPP MG
PN: 10580-00234 Rev. V
6-19
EVM (pk)
The peak (%) of all the error vectors, between the reconstructed ideal signals and the received
signals, divided by the RMS value of the ideal signals.
Freq Error
This is the difference between the measured carrier frequency and the specified carrier
frequency. This number is only as accurate as the frequency reference that is used, and is
typically only useful with a good external frequency reference or GPS.
Freq Error (ppm)
This is the frequency error displayed in parts per million.
TAE
Time Alignment Error (TAE) is a measurement of the differential transmission delay
between the Component Carriers. The 3GPP specification identifies the limits of the delays
for the system to operate properly.
Cell ID
Cell identifying information sent by the transmitter in the sync signal.
EMF (Option 444 only)
EMF measurements are available in Over-the-Air TD-LTE Signal Analyzer mode only when
Option 444 is installed. The option requires an isotropic antenna, at a frequency range that is
within specification of the instrument used. Refer to the isotropic antenna and spectrum
analyzer Technical Data Sheets.
provides connection instructions for the antenna and detailed
descriptions of the EMF Measurement menu and submenus.
Measurement Setup
Scanner
1.
Press the
Measurements
main menu key.
2.
Press the
Over-the-Air
submenu key.
3.
Press the
Scanner
submenu key to activate the OTA Scanner display (
). Press the
Scanner
key again to display the OTA Scanner menu.
a.
Press the
Sort By...
submenu key to list the Sort By menu and select the
parameter the OTA Scanner will use for sorting (Power, Cell ID, or Sector ID).
Press
Back
to return to the OTA Scanner menu.
b.
Press the
Show Mod Results
submenu key to display or hide the Modulation
Results of the strongest signal.
Note
When Show Mod Results is on, the overall scanner measurement speed is slower
due to the additional time required to demodulate the strongest signal.
Some instruments require the TD-LTE demod option to toggle this submenu to On.
