Microwave Measurements Laboratory


Class taught with Ralph Pasquinelli of Fermilab for the USPAS. Students are awarded full credit equivalent to graduate course at the host university. Taught at:

Hand-on labs include:

1.Spectrum AnalyzerMeasurement of simple signals on a spectrum analyzer to understand resolution bandwidth, video bandwidth, dynamic range, noise, etc.
2.TDRMeasurement of characteristics of various connector families, transmission lines, complex loads.
3.ComponentsMeasurement of the s-parameters of a variety of microwave components.
4.Beam SignalsUtilize an arbitrary function generator to simulate beam signals from the accelerator, AM for betatron signals, FM for synchrotron signals.
5.NoiseConsists of measuring the noise performance of a microwave amplifier. The amplifier will then be part of a “system” and noise performance of the system will be compared to individual noise performance of the components.
6.MatchingDesign and build a simple single stub transmission line matching circuit.
7.RF CavitiesMeasure mode spectrums of a cavity, the cavity coupling, loaded and unloaded Q, the electric field profile and R/Q of a cavity by the bead pull method.
8.Vector Signal AnalyzerUse of a vector signal analyzer for measuring Am and FM modulation.
9.WaveguidesMeasurements with LRL 550B Microwave Student Lab.
10.MixersMeasurements with double balanced mixers, linearity, conversion loss, intermodulation products.
