OTA Multipath Profile measurement with LTE/LTE-A TDD Analyzer
Control Channel
DL RS power is the resource element power of Downlink Reference Symbol. The absolute DL RS power is indicated on the BCH.
The absolute accuracy is defined as the maximum deviation between the DL RS power indicated on the BCH and the DL RS power
at the BS antenna connector.
The OTA Control Channel provides summary of all control channels including RS power trend over time. GPS coordinates (latitude
and longitude) will be displayed on the screen if a GPS antenna is connected and locked to the GPS satellites.
Setting measure setup
After configuring spectrum measurement in " Configuring Spectrum Measurements ", you can set the measure setup to continue your
measurement. The measurement settings can be saved and recalled as a file by selecting File Type as Setup and load the file onto
the instrument using the
Save/Load icons on the side bar.
1 Tap the Setup ( )icon on the side bar.
2 Tap Bandwidth and select the value from the following choices: 1.4 MHz , 3 MHz , 5MHz , 10 MHz , 15 MHz or 20 MHz .
3 Tap Subframe Number to set the number of subframe using the on-screen keyboard.
NOTE:
For MBMS testing, this subframe number must be either 0 nor 5 as these subframes 0 and 5 are not available for
MBMS and it must be set to the MBMS transm
itted channel’s subframe number.
4 Optional. Tap Physical Cell ID and select the type Manual or Auto .
Auto lets the instrument detect the Physical Cell ID for the LTE signal automatically, and Manual sets a specific Physical Cell
ID for the LTE signal manually in order to speed up the synchronization with a BTS.
5 Optional. To select the number of antenna ports, tap the MIMO and select 2x2 or 4x4 .
6 Optional. To assign an antenna port number automatically or manually, tap the Antenna Port under Antenna menu and select
the option: Auto , Antenna 0 , Antenna 1 , Antenna 2 , or Antenna 3 .
If the MIMO is set to 2x2, the antenna ports 2 and 3 are disabled.
7 To turn the Multimedia Broadcast Multicast Service ( MBMS ) feature on or off, tap MBMS and select On or Off . For proper
MBMS testing, you need to set the Subframe Number in the upper right screen with the same PMCH subframe number.
If this setting is on, the measurement item MBSFN RS appears in the result table.
8 To set the Multicast Broadcast Single Frequency Network ( MBSFN ) detection automatically or manually for MBMS testing, tap
MBSFN and select Auto or Manual .
An automatically detected or manually entered MBSFN ID appears on the screen.
