reselection decisions.
RSRQ provides additional information when RSRP is not sufficient to make a reliable
handover or cell reselection decision.
All of the parameters for OTA ID scanner can be plotted on map data such as Google Maps and
Google Earth by using JDViewer.
Setting measure setup
After configuring test parameters as described in the "Configuring test parameters" on page 173, you
can continue your measurement.
Procedure
1
Press the MEASURE SETUP hot key.
2
To set the nominal channel bandwidth to be measured, complete the following steps:
a
Press the Bandwidth soft key.
b
Select the bandwidth option from the choices: 1.4 MHz, 3 MHz, 5 MHz, 10 MHz, 15 MHz,
and 20 MHz.
3
Optional. Press the Miscellaneous soft key, and then do the following as needed:
–
To select the number of antenna ports, toggle the MIMO soft key and select 2x2 or 4x4.
This MIMO (Multiple Input Multiple Output) setting is activated only if the option 030 LTE-
Advanced FDD is installed with a license number. If not, the instrument sets this option to
2x2 by default. A 2x1 or 4x1 RF combiner is also required to able to test on MIMO
channels.
–
To select the cyclic prefix, toggle the Cyclic Prefix soft key and select Normal or
Extended. See "Appendix E – Cyclic prefix table" on page 534 for OFDM parameter details
by different bandwidth.
4
Optional. Go to SAVE/LOAD > Save, and then select the save option from the choices available
for your measurement mode. See "Using save" on page 32 for more information.
