Section 4 RF Testing
4.2.9 Test Equipment List
NOTE:
The test equipment outlined above is an example of typical equipment used to
perform the measurements. Other equipment with similar capabilities can be sub-
stituted. The serial nThe Qualcomm MER tool set consists of hardware and soft-
ware. In addition to the FSQ3 spectrum analyzer a Linux based PC is needed to
control the analyzer, a Linux based PC is needed to generate the test ASI stream
to feed the Apex exciters, and a GPS receiver to provide a 1PPS reference signal.
The software is provided by Qualcomm.
NOTE:
Rather than use two Linux PC’s a single, high performance, Linux PC could be
used to peform both functions. An additional Windows PC will be needed to ana-
lyze the measured data sets.
4.2.10 Transmitter Power Output
4.2.10.1 Objective
To verify the nominal rated RF output power (average) of the transmitter in digital
mode (FLO modulation).
NOTE:
The transmitter output power is measured at the forward output precision direc-
tional coupler located before the filter. The output of the transmitter must be con-
nected to an appropriately sized dummy load or to the MediaFLO channel filter
assembly which is connected to a dummy load.
