In today's crowded radio networks, the signal generators in wireless products must generate highly accurate and stable frequencies. To ensure that your wireless products use bandwidth efficiently, you can measure the phase noise in your signal generators with a spectrum analyzer and then evaluate the data with Matlab software. Furthermore, you can integrate the instrumentation and software into corporate networks, simplifying the documentation of test results.
