Spurious Responses Performance Test

This test verifies that the PSA Series Spectrum Analyzer meets its specification for input related spurious responses. In this test, the source is connected to the RF Input and set for the spur frequency. The source amplitude is measured using a power meter. The source frequency is then moved to the frequency location that will create the spur. The amplitude of the source is kept the same by using the power meter. The PSA then measures the spurious response at the spur frequency.
