NOTE
You can set
Auto to let the instrument detect the Physical Cell ID for the LTE/NR signal automatically and
Manual
to set the specific Physical Cell ID for the LTE/NR signal manually in order to speed up the synchronization with a
BTS.

Channel mapper measurement with DSS Analyzer
Control channel
The Control Channel measures the constellation for the specified control channel as well as modulation accuracy of the control
channel at the specified subframe.
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.

Tap to switch
Carrier Auto Search
to
Start
to start searching the SSB frequency and apply it or to
Stop
to stop searching.
NOTE
If searching is unavailable, the instrument displays a pop-up message saying that it fails to detect NR (SSB)
frequency.

Tap to switch
Radio Config
and set
Duplex Type
(FDD/TDD),
DSS Type
(Co-channel/
Adjacent channel
), and
Technology
(LTE/NR) and other related parameters as below:
You can select Co-channel to find NR frequency based on the LTE operating frequency in co-channel and select Adjacent
channel to search both LTE and NR frequency. Note that Adjacent channel will be available in the next release.
