I have an Agilent 8720ES that tests from 50MHz to 18GHz but my customer requires VSWR and Insertion Loss from DC to 18GHz.  I looked for rental equipment to do the testing, but I'm getting quotes for equipment that has tests 1MHz to 20GHz.  So how do I test DC to 18GHz on modern network analyzers?

Dear all, I have one issue while simulating band pass filter layout in ADS using short circuited stub. I am getting the following error: Polyline edges and/or wires have been found on STRIP layer <mask 2> and will be ignored. Their location has been written to the DRC report.   Can any one comment on the same?   Thanks & Regards, Vedang

Hi I am thinking of using 34980A System with some 34924A Multiplexer Modules. I read that there is availability of Internal Analog Buses from the connector at the rear of the mainframe with which one can connect to the Internal DMM and possibly also extend the number of modules. My goal is to multiplex more than 100 channels. So, My question is:… (Show more)

Click to view contentI want to mimic the layout TSMC 0.18um technology's Inductor to get approximately the same results using ADS Momentum tool at 10 GHz.Where it consists of M6 (Blue wire) and M1(Green wire), with the same dimentions of the original TSMS inductor layout there is a signifiacntly difference between the results of the TSMC saved data at ADS and the… (Show more)
