This thesis combines Keysight’s SystemVue software with a Vector Signal Analyzer (VSA) and Vector Signal Generator (VSG) to test receiver equalization schemes over physical channels. The testing setup, “Equalization Verification,” is intended to be able to evaluate any equalization scheme over any physical channel, and a decision-directed feed-forward LMS equalizer is used as an example. The decision-directed feed-forward LMS equalizer is shown to decrease the BER from 10-2 to 10-3 (average of all trials) over a CAT7 and CAT6A cable, both simulated and physical, for 1GHz and 2GHz carrier, and 80MHz data rate. A wireless channel, 2.4GHz Dipole Antenna, is also tested to show that the addition of the equalization scheme decreases BER from 10-5 to less than 10-5. Then the simulation and equalization parameters (LMS step size, PRBS, etc.) are changed to further verify the equalization scheme. The simulated channel BER results do not always match the physical channel BER results, but the equalization scheme does decrease BER for both wired and wireless channels. Then transistor-based equalization model is created using both HDL SystemVue components and blocks easily implemented by transistors. The model is then verified using HDL, Spice, and SystemVue simulation. Overall this thesis accomplishes its goal of creating a testing setup, Equalization Verification, to show that adding a given simulated equalization scheme in SystemVue can improve the quality of the link, by decreasing BER by at least an order of magnitude, over a specific physical channel.

The Road Telematics Communicator (RTC) as it is called in Scania. It is the device responsible to keep the vehicle connected and send the vehicle data to the off-board system. It uses data from different sources such as GNSS signals, CAN signal, and wireless Telecom signals. Connected vehicles provide real-time information on positioning, fuel consumption, and vehicle diagnostics. There are acceptance and regression test suites that verify the functionality of RTC. Third-party components such as the GNSS module are not a part of the tests due to technical limitations. Hence RTC lacks automated tests for important features. Due to the lack of complete verification in automated test suites, time-consuming tests must be performed on the road. And trouble reports from the field are difficult to analyze. This thesis provides testing the location accuracy of the GNSS module in vehicles used for telematics applications in the automotive industry, by using a GPS vector signal generator in a controlled lab environment. GNSS consists of GPS, GALILEO, GLONASS, BEIDOU. We are using GPS in this research. The GPS receiver is put under test in a controlled lab environment for testing the Time to First Fix, Location accuracy of GPS receiver, and analyzing the performance with the given inputs. Test cases were created similar to field tests on the signal generator. At this stage, an experiment is performed on the GPS receiver which is connected to the signal generator via RF connector and to a computer via LAN. An input data is sent to the signal generator in the form of SCPI commands. The signal generator processes these commands and generates a signal accordingly. This generated signal is fed to the receiver. With the help of a signal generator, we can generate fields like inputs and verify the behavior of the GPS module. By verifying the behavior of the module, we can develop test cases that show the functionality of the receiver.
