Cyclic prefix
defines the type of signal the scanner is set to measure. With
Autodetect
selected, the scanner will automatically detect the appropriate signal type. If Cyclic Prefix is
known to be Normal (most common), setting the scanner to Normal will increase scanning
speed slightly.
Uplink-downlink configuration
refers to LTE TDD frame structure.
Frame structure type 2 is applicable to TDD. Each radio frame of length

reserved for downlink transmissions, “U” denotes the subframe is reserved for uplink
transmissions and “S” denotes a special subframe with the three fields DwPTS, GP and UpPTS.

3. After making the appropriate settings, click OK and OK again and go to online mode to start
the scanning.
4. A green light on the scanner Device Status window should start blinking. This means that the
device is working properly and scanning using the default settings. In TOP-N Mode this may
take a few seconds.
5. Click the Start Recording button
to start recording the results in an output file.
