Answer Key Touchstone 4

[Irati Klute]

Whileyou are interviewing at touchstone, the recruiter might ask you why you want to work at touchstone. here are 3 answers in a professional funny and Informal tone that you can use to convenience the recruiter that you are really interested in working at touchstone based on the situation

?I am excited to work at Touchstone-Inspections because of the company's commitment to providing quality inspection services. This company's dedication to its customers is evident in its commitment to continual improvement and its focus on customer satisfaction. I want to be a part of a team that is committed to providing the best possible service to its customers.

?There are a few reasons. First, I like the company's mission and values. Second, I think the company is doing interesting work in the field of quality assurance. Finally, I think it would be a great place to learn and grow my career.

Radiology technicians are trained and licensed to perform the procedure. This is a specialized skill that allows them to collect quality images that are then passed along for interpretation by a radiologist. A radiologist is a medical doctor who had special training in reading and interpreting medical images. For the most part. Even the radiologist will not make a diagnosis, they will simply state what is visualized. Whether an image shows normal tissue or an organ or any abnormalities they note.

Once a radiologist has interpreted the images, your medical provider will use these results as a tool in making a diagnosis. They will evaluate the impressions against the other available evidence including lab work, physical exam results, and your medical history to develop a working diagnosis.

A radiology technician who makes a diagnosis or even offers a guess, is working outside their scope of practice and can lose their ability to continue practicing. Incorrectly interpreting results can cause needless anxiety, worry, and may even result in medical errors. Questions your medical imaging specialist is not allowed to answer for you include:

21st-century medical imaging technology is astounding. Technology, equipment, techniques, and software offer images that were unfathomable in decades past. Images are available immediately and results are interpreted much quicker. The digital ability for radiologists to view images off-site mere seconds after they are captured leads to lightning-quick results. And, with the wide-spread availability of patient access to their electronic medical record, you can view the preliminary results online, often times, the same day.

With information available at any internet users fingertips, misinformation and needless worry is bound to ensue. Your medical provider will be able to answer all of your questions, even the ones your radiology technician is not allowed to.

If your provider has ordered a diagnostic imaging test for you, make an appointment at one of our medical imaging clinics near you. All of our clinics are equipped with state-of-the-art medical imaging technology, and certified by the American College of Radiologists. Your medical provider will receive the highest-quality images interpreted by a board-certified radiologist. Our patient-centered care will leave your only question answered, your definitive diagnosis. Visit us online to schedule your appointment today!

I know that a rfm file is accepted, we just need to choose "rfm" as the data format in the nport form. Is there no possibility to directly use a bbspice file in this way?

Before you ask why I am not letting cadence generate the bbspice file for me, let me answer that question. The conversion seems to take really long when done in spectre. With ADS it is generated really fast.

Another question related to this, is the S-parameter data format "spectre" not supported as well? I can generate both a bbspice and a spectre file in ADS from an existing citifile. Can I not use this spectre file directly with the nport? At least the possibility seems to be present. But when I tried to do that, I am getting the following error.

The scs file looks ok to me. Here is a snippet :

Any suggestions on what is going wrong here?

Regards,

The spectre format for s-parameter files is just an alternative format to Touchstone. It's still in terms of real/imaginary or phase/magnitude for the matrices of s-parameters at each frequency; it does not just mean you can use a spectre sub circuit instance.

You could use RFM if coming from an external rational model creation tool such as ADS broadband spice, or if including a spectre subckt model as you have here, that can't be done with an n-port. You need to create a component which has the right pins and netlists in the right order - maybe the Keysight integration can take care of that (that's a question for Keysight, not us).

I would also suggest that you contact customer support about using the built-in bbspice. First of all, make sure you're using a current version of Spectre, and take a look at Tawna's 7 Habits of Highly Successful S-Parameters application note. If you're still seeing performance issues with the translation, then we'd welcome you to contact support so that we can investigate further.

So I understand you correctly, you are saying that we can't directly use a bbspice file in the nport for simulations.

It is also not possible to use the .scs file generated by ADS with the nport, like shown below.

It rather depends what you mean by a "bbspice file". If the Keysight Broadband SPICE tool produces an RFM file, then you can use it with nport. The nport cannot however use a spectre netlist (i.e. a spectre subckt). The "spectre" format is (as I said earlier) a spectre syntax file for s-parameters, and looks like this - it does NOT mean a spectre netlist:

Everything you ever wanted to know about the nport is here: 7 Habits of Highly Successful S-Parameters, Spectre 21.1 (note that this is a more recent version than what Andrew mentioned) or in Spectre Classic Simulator, Spectre APS, Spectre X, and Spectre XPS User Guide -- Modeling for Signal Integrity

rfm (an HSPICE format). It will contain a header (first 5 lines) which contains information on the number of ports, and the matrix type (S or Y for example). The data fields consist of rational function coefficients.

Thanks Tawna. I have already gone through your "7 habits ... " pdf some time back. Although I believe it was an earlier version,not the 21.1.

As to the suffix of .scs, it is how ADS generates this spectre version of the sp file. To me it made sense as spectre does use .scs file extension. Anyways, below is a snapshot of all the different files ADS can generate from a touchstone file.

The suffix .bbn is the broadband spice file that I was trying to use. Tried the other file formats as well but nport can't read them.

Unfortunately ADS cant generate a RFM file. We have to use a separate tool for that and there are very few licenses available for it. It's a nightmare to get transient simulations run for RF designers :D :P

As I've now said several times, nport is designed to read s-parameter-like data; it also support RFM (Rational Function Matrix) which is a rational model format. If you have a SPICE or Spectre sub-circuit, then the nport would be superfluous - all you need to do is instantiate the subckt.

If you don't want to create your own symbol (which could easily be done by creating a spectre text view and pasting in the generated SCS file contents; you'll be prompted to create a symbol afterwards), you could use this approach: How to create pcell symbol with variable pins and write custom netlist procedure for spectre and then you can reference the file as a model file.

Read the latest version of the Appnote. It's been updated. Seriously - a Customer Support AE can assist you with this. Please file a case on . Andrew and I answer questions in our "off work hours". You'll get consistent, trackable support for the Customer Support team. If it's past my dinner time, you'll get cranky responses from me.

Thanks. This is interesting, I have never used the spectreText view before. I gave it a try. Had a small issue and Customer support helped me. Could run the simulation with spectreText view, the output looks really patchy (more than the touchstone data), but that is probably another issue.

Thanks for all the support.

There are many important theological questions that are worth struggling with, but the questions that stir our theological passion and return to stir us to further examination are usually questions that arise from our own personal story. An exciting or distressing theological question is usually one that comes out of our pain or our joy. It often is so important to our existential wellbeing that we cannot let it alone. Questions of theodicy, questions concerning the reconciliation of belief in God's goodness with the existence of evil and suffering, are among the passionate existential questions. They come out of my own story. "Why me?" is not a textbook question but rather a question that comes out of my life and stirs my passions every time it returns. I believe that the important existential questions do return repeatedly, for they are questions of the heart, not of the head. We may have excellent answers for the questions, but they do not quiet the heart's ache. The heart cries, laments, and complains, and although it expresses itself in the language of a question, an answer will not satisfy the lament of a heart.

One who honestly and courageously faced the theodicy questions of his story was the man of Uz named Job. I like Job. I know that he is sometimes portrayed as a self-centered male who was more concerned about his own pain than the pain experienced by his wife, the mother of their children. However, that self-centeredness is often typical in the life of one who is overwhelmed by theodicy questions. At least Job confronted his own suffering and cried out his defiance and his pain. Job was not quiet, nor was he patient. He trusted God, and God trusted Job.
