There are a number of Agilent/Keysight vector network analyzers (VNAs) in the department. Here are some links to help you get started with the prerequisites of understanding coax connectors and cables as precision RF instruments in a VNA measurement:
00_EquipmentCare_ECals_Cables_NetworkAnalyzers_Cory119Lab.pptx
01a_Making_AmphenolRF_Conformal_Cables - these connectors and tools are in the Cory 119 instructional lab
01b_Making_Santron_Conformal_Cables - these connectors and tools are in one professor's research lab, but posted here if you want to buy these parts/tools for your lab
02_Calibration_with_85093-60008_ECal.pptx - this ECal is in one professor's research lab, but the general principles are the same for various ECal models
03_Calibration_with_N4691-60006_ECal.pptx - this ECal is the model we have in the Cory 119 instructional lab
Agilent_Network_Analysis_Basics_Presentation - a video presentation created by Agilent, gives an overview of what "network analysis" means in terms of VNAs
The EE142/EE242 course taught by Prof. Niknejad has a lab component which uses VNAs heavily. While there is more information on those courses' web page, here are some videos taken when Dr. Joel Dunsmore from Agilent visited the class and gave some lessons on particulars of VNAs:
