A communication satellite is in stationary (synchronous) orbit about the earch (assume
altitude of 22.300 statute miles). Its transmitter generates 8.00 W. Assume the transmit-
ting antenna is isotropic. Its signal is received by the 210-ft diameter tracking parabo-
loidal antenna on the earth at the NASA tracking station at Goldstone, California. Also
assume no resistive loss in either antenna, perfect polarization match, and perfect
impedance match at both antennas. At a frequency of 2 GHz, determine the:
(a) power density (in watts/m²) incident on the receiving antenna.
(b) power received by the ground-based antenna whose gain is 60 dB.

50mV and 10kHz from the function generator to the input. The mulitmeter postive is connected to the output and negative to a ground. Is the circuit connected correctly? Yes or No. Does the reading look correct? I don't need calculations but will take them. I just need to know if the connection is right.
Connect a signal generator to the input and set it for 50 mV Sine wave with a frequency of 10 kHz. Connect the output to a multimeter set to RMS voltage. Record the output voltage and frequency in the following table. Repeat the measurement for all given frequency values in the table.
