DAB-XPlorer / DABXP / DABRF
– Getting Started

5.3.3 Coverage measuring
Setup
•
DABRF-HWU or DABRF-RM
•
DABRF-RX
•
DABRF-PC
•
DABRF-OCC
Uses
Use the DABRF with DABRF-RX to record extended EDI files in test drives. After the
measuring journey, use the GPS-Campaign-Converter (DABRF-OCC) to make KML files
from your recorded EDI files. Open the KML files in Google Earth to get a presentation of the
results. Consider using a scripting language (like Python) to extract data from the KML file for
further statistical evaluation.
With the same test equipment and statistical evaluation, suppliers of car antennas can
compare different antenna setups doing several subsequent measuring journeys on the
same route.
5.3.4 SFN test
Setup
•
DABRF-HWU or DABRF-RM
•
DABRF-RX
•
DABRF-PC
Use
Choose one transmitter of your network as reference for the timing of the whole SFN.
Measure the parameter
Time Position
and press the
Resume
button to copy the value into
the field
Reference
in the
SFN
panel of the
ETI-XPlorer
window. Visit every transmitter within
your network and check if
Deviation
is zero or equal to the wanted additional delay of the
transmitter under test.
5.3.5 Receiver test
Setup
•
DABRF-HWU or DABRF-RM
•
DABRF-RX
•
DABRF-PC
•
DABRF-TX
Uses
Software test with real-life scenarios
Use the DABRF to record EDI files from on-air signals with content that is interesting for your
receiver tests. Replay the recorded EDI files with the DABRF-TX player to produce the RF
signal to test your receiver.
The analyser functions coming with ETI-XPlorer, FIC-XPlorer, and FIC-XTractor will be
helpful to check the integrity of the caught ensemble configurations and to research strange
compatibility issues.
