Canadian limit is f/30, but the FCC limit is more
stringent). The power density is calculated as:


Max Pd = 960/300 = 3.2mW/cm2
Pt = +23dBm = 200mW

The local oscillator of the receiver is 916MHz. When measured off of the antenna port,
the receiver could not be found. An attempt was made to perform this measurement at
the three meter site. Again, the receiver could not be found.

             Appendix A – Antenna Substitution Method of EIRP Measurement

            First, measure the field strength of the device in accordance with the procedure in
       Appendix B. Second, replace the device with an antenna and connect the antenna to the
       output of a signal generator. Set the signal generator to the same frequency as the device
       emission that is being measured. Adjust the height of receiving antenna to give the
       highest reading. Repeat with the substitution antenna in the vertical position. Bring the
       position back to the polarity and height that results in the highest field strength reading.
       Set the signal generator to a power that results in the same field strength reading as that
       of the device emission. The gain of the transmitting antenna, output power of the
       generator, and loss of the cable can then be used to determine the EIRP of the device.

               Field Strength = ACF1 + Cable Loss1 + Ground Plane + DUT Output




Field Strength = ACF1 + Cable Loss1 + Ground Plane + Cable Loss2 + Antenna2 Gain + RF Source which produces a level equivalent to DUT


            Appendix B – Field Strength Measurement Procedure

     This test measures the field strength of radiated emissions using a spectrum analyzer
and a receiving antenna in accordance with ANSI C63.4-2003. During the test, the EUT
is to be placed on a non-conducting support at 80 cm above the horizontal ground plane
of the OATS. The horizontal distance between the antenna and the DUT is to be exactly
3 meters. Levels below 1 GHz are to be measured with the spectrum analyzer resolution
bandwidth at 120 kHz and levels at or above 1 GHz are to be measured with the spectrum
analyzer resolution bandwidth at 1 MHz.

1) Monitor the frequency range of interest at a fixed antenna height and EUT
azimuth.
2) If appropriate, manipulate the system cables to produce the highest amplitude
signal relative to the limit. Note the amplitude and frequency of the suspect
signal.
3) Rotate the EUT 360° to maximize the suspected highest amplitude signal. If
the signal or another at a different frequency is observed to exceed the
previously noted highest amplitude signal by 1 dB or more, go back to the
azimuth and repeat step b). Otherwise, orient the EUT azimuth to repeat the
highest amplitude observation and proceed.
4) Move the antenna over its fully allowed range of travel to maximize the
suspected highest amplitude signal. If the signal or another at a different
frequency is observed to exceed the previously noted highest amplitude signal by
1 dB or more, return to step b) with the antenna fixed at this height. Otherwise,
move the antenna to the height that repeats the highest amplitude observation
and proceed.
5) Change the polarity of the antenna and repeat step b), step c), and step d).
Compare the resulting suspected highest amplitude signal with that found for the
other polarity. Select and note the higher of the two signals. This signal is termed
the highest observed signal with respect to the limit for this EUT operational
mode.
