5. d) The transmit power of a satellite is 20 W. The gain of the transmit antenna is 30dB while the gain of the receive antenna is 20dB. Distance from the satellite to the ground receiver antenna is approximately 1000 km. The operating frequency is 9 GHz.  Recalling the following “Friis” relationship governing received  and transmitted power between 2 antennas separated by a distance R (Hint: you don’t want to use dB or dBm values for any quantities in this equation. )  Choose from the following options the one that best fits the power level in dBm received at  the output of the ground antenna  

  Assume you are testing a mixer using the test configuration above. And that you have measured the spectral response at the output of the mixer and have corrected  for the IF output cable and pad at all frequencies.  Now you want to compare your data to what may be expected from manufacturer data sheet information for the mixer.     The mixer’s data sheet information includes the intermodulation table below, and that you setup the RF and LO  frequencies as indicated below the table as test conditions and adjust the power levels for each such that they are -14 dBm @2850.1 MHz  and +7dBm @2880.1 MHz at the RF and LO ports, respectively.   Note in the intermodulation table below all values are in -dBc (values below the carrier) except where indicated with a “+” sign. For each question, pick the closest answer to what you come up with.

In an essay of no less than 250 words, answer the following:   According to the National Institute of Standards and Technology Special Publication (NIST SP) 800-100, “risk is a function of the likelihood of a given threat source’s exercising a particular potential vulnerability, and the resulting impact of that adverse event on the organization.” Therefore, risk is an equation that includes likelihood, threats, vulnerabilities, and impacts. Define an example information system and describe the risk assessment process and the resulting risk calculation as applied to that hypothetical information system. Be sure to include the categorization/characterization of your hypothetical information system as part of your calculation.    Be sure to cite your sources if paraphrasing or quoting others, and expand all acronyms for clarity. Do not use sources from outside this course’s materials, as this will lead to a score of 0 points for this essay.
