Dear Newsgroup Members, I thought I'd try sending the first message as a test since we have 9 people signed up so far. Feel free to post to the newsgroup with...
Hi Roger- Jeff was working on setting up the question and answer "clubs" we discussed earlier. The first step was understanding how the yahoo sites work, so he...

I am curious as to why the MTT chat Groups are not part of the IEEE Online Communities; for information go to: https://www.ieeecommunities.org...
hi all, I am a masters student at Indian institute of science, bangalore and am working on RF MEMS based distributed phase-shifter. I had a doubt regarding...
Dear Indrajit, You might look at this paper: * <file://papers/cpwons~1.pdf>D. F. Williams, M. D. Janezic, A. Ralston, S. List, "Quasi-TEM model for coplanar...
I would like to know if you have software available to load the 12-term VNA calibration coefficients from statistiCAL into the HP8510 VNA. In NISTcal, I am...
In general, we only use NISTCal for 4-port calibrations. If you are performing 2-port calibrations, you would better off using MultiCal or StatistiCAL. Here...
Hi This will be my first time to perform 4 port measurement with PNA. Could you let me know what is the best way to perform 4-port calibration with both SOLT...
Hello, I need some help about implementation of matched filters, or correlators, in Lab View. I am new in Lab view and know only its basics. I need to develop ...
Hi, I am trying to measure and model a comunication laser diode (TOSA) in a TO can. In this case it is a 1550nm wavelength DFB laser intended for 2.5Gbps. It...
Dear Cory, In my experience, on-wafer probes can be made to work quite nicely with TRL standards printed on PCB. I would consider establishing your first-tier...
Hi, I am looking into what is the most practical method to add optical capabilities to my 8510C. I need to be able to measure communication laser diodes and...
Hello Cory, I believe that you are correct that the most inexpensive way to proceed is to use a calibrated photodiode. I am not sure how much Anritsu sells...
Dylan, I contacted Anritsu, and they only support 1550nm for now, and their list price is about 25K. Do you know of any other vendors that are selling ...
Hello Cory, If you are interested in power calibrations, I think that Agilent, New Focus, Newport, U2t, perhaps other options exist. Some of these might have...
Are you guys talking about the contactless probing solution? Sorry about that if not. A few years back, I heard that people used optoelectronic probe to do ...
Hello Fei, It still is very difficult to measure scattering parameters with non-contact means. Nevertheless you might find this paper our group wrote on the...
Hello I've been following Doug Rytting presentation called "TRL Calibration". The equations all make sense and give good results however the presentation does...
Sorry Igor, When de-embedding adapters you can use reciprocity (S21=S12) to solve this problem. Both MultiCal and StatistiCAL allow you to solve for adapter...
Thank you Dylan When S21=S12 there is a 180deg ambiguity in the answer because of the square root function. Similarly, there is a square root to solve for S22...
Hello Igor, In MultiCal and StatistiCAL you put in an estimate for the length of the fixture. The programs use this estimate at the lowest frequency to resolve...
