DIGITAL TELEVISION (DTV) FIELD STRENGTH

AND VIDEO QUALITY STUDY

J. Wayde Allen and Ted Mullen 

A particular concern about digital television (DTV) broadcasts is whether such broadcasts have sufficient

power to be received using inexpensive indoor antennas located inside a typical home. To test this, the

Institute for Telecommunication Sciences (ITS) constructed a “simulated home” mounted on a flatbed

trailer. This allowed ITS to move the test home to a number of locations in the vicinity of an operating

commercial DTV transmitter. By equipping this test home with commercially available DTV receivers

and an indoor antenna located at the center of the home, ITS could then observe and record the DTV

reception at a number of test locations. This information was further correlated with the incident field

strengths by measuring the signal power outside the structure at a height of 10 meters above ground and

at a location inside the structure at a height of roughly 1.5 meters above ground. This report summarizes

the results of this study.

1 INTRODUCTION

As the deployment of digital television (DTV) moves forward, a number of concerns have been raised regarding the

power limits placed on the technology. Of particular concern is whether reception of DTV is possible using commercially available DTV receivers and inexpensive set top or “rabbit-ears” antennas positioned at arbitrary locations in a

home. Since over-the-air DTV broadcasts are currently available in a number of metropolitan areas, one can test DTV

reception in a number of home sites. However, since houses located in different areas are constructed using a variety

of materials and are not all furnished the same way, analysis of such data is difficult. There are simply too many variables. If no picture is obtained at one location, how can one determine if the lack of reception is caused by too little

power, multi-path interference caused by reflections of the DTV signal off of nearby objects, obstruction of the signal

by intervening structures, interference of the signal by some local noise source, or differences in the construction of

the two buildings?

There are several ways that one can deal with this problem. One approach is to account for as many variables as

possible. Another is to try and control the number of experimental variables in order to make the problem more

tractable. For this test, ITS chose to limit the number of variables by constructing a simulated home that could

be moved to a number of test locations. This eliminated the problem of trying to compare data taken in different

structures and allowed ITS to look specifically at how location and power affected the reception of DTV signals inside

a structure.

2 THE TEST

2.1 Hardware Requirements

The major elements of the test setup include: 

Simulated Home Enclosure 

VHF/UHF Indoor TV Antenna 

Two Commercial DTV Receivers (different brands and chip sets) 

Digital Camcorder 

TV Monitor 

GPS Receiver 

Calibrated Dipole Antenna 

Spectrum Analyzer

To improve the approximation of the enclosure to a typical house, the structure included a window in the broad

wall, was insulated with fiberglass, and was paneled with 1/4 inch plywood. All of the equipment was assembled as

diagrammed in Figure 1.

Both the indoor TV antenna and the calibrated dipole antenna could be mounted inside the test enclosure at the same

location. This allowed ITS to position the indoor TV antenna for recording the DTV receiver’s video signal, or to

measure the field strength at this location using the calibrated dipole and spectrum analyzer. Additionally, mounting

the same dipole antenna on a 10-meter mast allowed ITS to position it outside the enclosure at a height of 10 meters

above ground for an external field strength measurement. This height approximates the location of an external antenna

located on a representative home.

2.2 Test Procedure

The following test procedure was followed at each of the locations where observations were made.

1. Park the test structure at a test location. The orientation of the structure was random to the extent that the vehicle

could legally and safely be parked at the chosen location.

2. Connect the indoor TV antenna to the first DTV receiver.

3. Tune the DTV receiver to an available DTV broadcast. In this case, the station was KDVR-Denver, located on

channel 32 with a center frequency of 581 MHz, and authorized to broadcast from Lookout Mountain in Golden,

Colorado, with an effective radiated power of 233 kW.

4. Choose the field strength indicator display from the menu on the DTV receiver and adjust the antenna to obtain

the best signal as reported by the DTV receiver display. The antenna adjustments were only those built into the

antenna, namely rotation and tilt of the loop element. In all cases the antenna location remains constant at the

center of the test enclosure.

5. Record the video output from the first DTV receiver.

6. Connect the indoor TV antenna to the second receiver, adjust, and record the video as was done for the first

receiver.

7. Replace the indoor TV antenna on the mounting post in the center of the test structure with the calibrated dipole

antenna connected to the spectrum analyzer. Position the dipole elements in the same plane as the indoor TV

antenna element.

8. ITS was interested in measuring the upper limit of the power since this indicates the most power one is likely to

see at the test location. Since the KDVR signal has a center frequency of 581 MHz and a nominal bandwidth

of 6 MHz, configuring the spectrum analyzer with the following settings takes 601 peak power samples with a

6-MHz bandwidth centered at 581 MHz: 

Center Frequency: 581 MHz 

Span: 0 Hz 

Sweep Time: 100 ms 

Resolution Bandwidth: 6 MHz 

Video Bandwidth: 6 MHz 

Peak Detector

9. Record the field strength trace data from the spectrum analyzer.

10. ITS was also interested in recording the shape of the DTV signal envelope. This was accomplished by reconfiguring the spectrum analyzer to provide a narrow band (100 kHz) power sweep across a frequency range larger

3
than the DTV signal bandwidth. This was done by reconfiguring the spectrum analyzer with the following

settings: 

Center Frequency: 581 MHz 

Span: 10 MHz 

Sweep Time: 100 ms 

Resolution Bandwidth: 100 kHz 

Video Bandwidth: 100 kHz 

Peak Detector

11. Record the trace data from the spectrum analyzer as configured in 10.

12. Mount the dipole antenna on the 10-meter mast and raise the mast into position.

13. Repeat the same set of spectrum analyzer measurements at the 10-meter height with the spectrum analyzer reset

for the field strength measurements as in step 8. The one difference is that the analyzer’s detector is set to

“peak hold” so that the analyzer indicates the maximum signal when the antenna is rotated about its axis. This

eliminates the need to find the antenna polarization giving the maximum signal before taking a reading.

14. Rotate the dipole mast around its axis 360 degrees and record the resulting field strength trace.

15. Configure the spectrum analyzer to record the shape of the DTV signal envelope as was done in step 10.

16. Record the trace data showing the DTV signal envelope as seen at 10 meters.

17. Record a description of the test location and the GPS coordinates.

2.3 Uncertainties

Since this report is anecdotal in nature, a high degree of measurement accuracy was not expected. Nevertheless, the

following should give the reader a reasonable estimate of the experiment uncertainty.

For our field strength measurement we measured the power of the DTV signal in a 6-MHz bandwidth and computed

the field strength using the expression [1, pg. 9]:

Fs  Pmedian  Gcable 	 77 
 2  20log  f  Gantenna (1)

where:

Fsis the field strength  dBμV 
m ,

Pmedian is the median power computed from the spectrum analyzer trace  dBm  ,

f is the center frequency in MHz (in this case f  581),

Gcable is the loss of the cable connecting the antenna to the spectrum analyzer (in dB), and

Gantenna is the gain of the antenna (in dBi).

4
For our particular equipment our uncertainties are estimated to be:

∆Pmedian 1 dB  26%  (2)

∆Gantenna 2 dB  58%  (3)

∆Gcable 2 dB  58%  (4)

The frequency accuracy given in the spectrum analyzer documentation is 0 
 2% of the span or 1 
 2 MHz so the

frequency term can vary from 20log  579 
 8   55 
 27 to 20log  582 
 2   55 
 30 giving an estimate of ∆20log  f  

0 
 02. This certainly contributes very little to the overall uncertainty and for this estimation will be ignored.

Combining the fractional uncertainties of the ∆Pmedian, ∆Gcable, and ∆Gantenna terms in an RSS summation gives the

following estimation for the Type-B measurement uncertainty [2]:

ub  

∆P

median  ∆G2cable  ∆G2

antenna 0 
 262  0 
 582  0 
 582  0 
 86 2 
 7 dB  (5)

Since there are no repeat data at any given point with which to estimate Type-A uncertainties [2], this information must

be estimated from past experience. Similar testing done using the Radio Spectrum Measurement System (RSMS) has

shown spectrum analyzer measurements with repeatability on the order of 0 
 5 dB or approximately 12%. This is a

reasonable estimate, and results in the following estimate of combined uncertainty

This gives an expanded uncertainty with a 95% confidence limit  k  2  of

UFs  2uFs  1 
 74 4 
 4 dB  (7)

which describes the “best” measurement accuracy obtainable with this test setup.

3 RESULTS

After collecting data at each of the locations, the median peak power was computed from the 1.5-meter and 10-meter

field strength traces (581-MHz center frequency, 0 span, 6-MHz resolution bandwidth). However, since this test was

performed as quickly as possible, there were a few instances where our spectrum analyzer trace data did not get saved

to disk. This occurred at locations 4, 24, 25, 26, 27, 28, 29, and 30. At these locations it was not possible to compute

a median and we were forced to use the operator’s hand written record of powers read directly from the spectrum

analyzer screen. Field strengths were computed using equation 1, and the resulting field strengths from both sets of

data are tabulated along with location and whether a television picture was received on receiver 1 (Rcr 1) or receiver

2 (Rcr 2) in Table 1. All available trace data has been included at the end of this document in Appendix A. A second

set of data taken a few weeks later is included in Appendix B. This second data set includes measurements of the root

mean square (rms) levels in addition to the peak values.

A formal quality assessment of the received picture was beyond the scope of this experiment. The determination of

whether a “picture was received” or not was based on the following decision criteria: If a receiver was able to display

a picture for some portion of the observation time, then the reception was deemed successful and a “Y” was entered in

5
the data table. If no picture was seen at all during the observation time, then the reception was deemed unsuccessful

and an “N” was recorded. You may also note a few cases indicating that data was not available (NA) for receiver 1.

This condition occurred early in the test before it was discovered that the receiver was not properly tuned to the test

signal. Consequently, there are no data in these locations to indicate whether this receiver would have picked up the

DTV transmission or not.

The test locations have also been overlayed on top of a field strength prediction map in Figure 2. Here it is important to

note that peak field strengths were measured in order to understand the upper bound on the received signal. In contrast,

the computer models compute average field strengths, and will indicate a lower predicted field strength. One should

also recognize that the computer models assume that the station’s transmit power and antenna pattern exactly match

what is on record. Confirmation of this would require testing at the transmitter, which for this study was not possible.

Finally, the video clips recorded from the test receivers were also edited to create a DVD recording. This shows the

recorded video from each receiver overlaid with the location and field strength data as tabulated in Table 1.

4 CONCLUSION

This test provides an indication of how well DTV signals can be received in the Boulder area from an existing station

located on Lookout Mountain and operating with an effective radiated power of 233 kW. It also makes clear that power

alone is not the only variable to consider. This is particularly evident at location 9 (Figures 34 - 37) where no video

was obtained from either of the test receivers even though there is a significant field strength at this location. Compare

this for instance with location 19 (Figures 74 - 77) where there is less field strength than at location 9 and video was

obtained from both receivers. Of particular interest are the differences between the two graphs seen in Figure 35 and

Figure 75. Figure 35 shows that in spite of there being more power at this location, the shape of the DTV signal has

been distorted, presumably by multi-path effects, such that the receiver is unable to reconstruct the digital video stream

even though there is more power available at this location. Power level is clearly not the only important variable for

the reception of DTV.

A much more comprehensive study could be conducted to help quantify DTV image quality. Such an experiment

could look for not only correlation between signal power and received video quality, but also correlations with such

deleterious effects as multi-path interference, shielding, and noise.

APPENDIX A: DATA SET ONE

The following graphs show the spectrum analyzer trace data collected during the first part of the study. As has

already been noted, there are a few locations where no trace data was saved to disk. These locations were: 4, 24, 25,

26, 27, 28, 29, 30, and consequently there are graphs missing at these locations.

APPENDIX B: DATA SET TWO

After gathering the data presented in Appendix A it was requested that more data be collected in the area to the North

and East of the city of Boulder. Additionally we were asked to include measurements of the root mean square (rms)

levels in addition to the peak values as reported in the first data set. The measured field strengths are shown in

Table 2, and the graphs in Figures 94–141 show the spectrum analyzer trace data.
