Appendix A - Measurement Systems 
 
 
This appendix provides information regarding the measurement equipment used to perform 
this test/measurement program.  Table A-1 provides a list of the equipment used, including the 
manufacturer and model number, a brief description and where appropriate, the most recent 
calibration date. 
 
Calibration information resulting from measurements performed in the laboratory to 
determine the signal attenuation in various circuits used to support the test/measurements is also 
provided.

 The following information is provided with respect to calibrations performed as a part of 
this program to determine the signal attenuation (or gain) associated with the various 
components used to support the test/measurements. 
 
 The input signal level used in the detection threshold was set at the input to the WSD 
scanner antenna input port and thus, no signal calibration was necessary.

 A short length (2-feet) of RG-223/U coaxial cable was used to connect the WSD 
transmitter output port directly to the spectrum analyzer for performing the transmitter emissions 
measurements.  The signal attenuation in this cable was measured and found to exhibit a 
maximum loss of 0.4 dB over the frequency range involved (512-698 MHz).   The insertion loss 
associated with the channel-reject (notch) filter is 2.9 dB, including the additional coaxial cable 
used to integrate into the measurements system. 
 
 The OTA interference test utilized a log periodic antenna as the test antenna and it was 
connected to the DTV receiver (or spectrum analyzer) with a 20-ft length of RG-55 coaxial 
cable.  The signal attenuation in the cable run was measured and determined to be a maximum of 
2.3 dB.  In addition, there was a measured signal loss associated with the impedance-matching 
transformer of 0.9 dB and the antenna gain over the 512-698 MHz frequency range is 7.1-7.5 
dBi. 
 
 
 
 
Appendix B - Service Contours of TV Stations at Field Test Sites 
 
 
This appendix contains plots depicting the service contours of each full service 
and low power TV station on channels within the prototype WSD tuning range that have 
been authorized for use by a licensed television broadcaster relative to each site where 
field measurements were performed.  The test location is represented on these plots by a 
red star.  All broadcast licensees and construction permits within a 150-km (94-mile) of 
the test site were included in the contour plots.  Red circles indicate DTV stations; blue 
circles indicate analog TV stations.  There are a total of thirty plots provided for each test 
site, one for each channel in the WSD’s tuning range.
