# Display impedance on Genesys' Smith Chart?

Hi Guys,

Something that has wasted hours of my time, and without any
success: I'm trying to make the Agilent Genesys linear simulator show
me the complex (rectangular) input impedance of a circuit, and display
that impedance (through a marker) on the Smith Chart, rather than just
as polar S11. (A Genesys Table display can do it easily...). The ZIN1
parameter does not even seem to work (I had thought it had, some years
ago). Surely there is a way! Anyone have any ideas on this??

Thank you!

-Bill

(PS: I was also trying to make the graph's marker text larger, but
that failure is just too painful to talk about).

No pun intended but that's one reason I use a real Smith Chart. Then
ones where they first have to fell a tree ...

True Joerg, but all of the software Smith charts I have ever used
allow this capability too. And for some reason, most people in this
newsgroup don't seem to be very familiar with Genesys, so I guess its
no REAL-IMAGINARY impedance's for me (at least on Eagleware's Smith
chart tool)!

Best,

laughs. Maybe you need to import into Agilents free tool Appcad to do

Seriously, there has to be a setting... doesn't there?

Eagleware? Yeah, if you work in a huge business where several thousand
Dollars are considered chump change, or if your name is Rockefeller. My
only expense is about $1 for new compasses when traveling because the TSA guys won't let them on board. J #### Joel Koltner Jan 1, 1970 0 Joerg said: Eagleware? Yeah, if you work in a huge business where several thousand Dollars are considered chump change, or if your name is Rockefeller. The "full" version of Genesys (now owned by Agilent -- they bought Eageware something pushing a couple of years ago) is ~$20k. Certainly not cheap, but
very much within reach for any copmany with more than a handful of decently
paid engineers. (I mean, if you have a half dozen engineers these days, you
company must be burning something pushing a million bucks a year...)

It was probably something like$20, but well worth it -- compared to the $1 compasses I was able to draw much better circles. ---Joel J #### Joerg Jan 1, 1970 0 Joel said: The "full" version of Genesys (now owned by Agilent -- they bought Eageware something pushing a couple of years ago) is ~$20k.

But imagine how many parties $20k could throw for the guys I still find it a bit on the expensive side. I have occasionally used similar luxury suites at clients but afterwards never felt enticed to plunk down the equivalent of a new car myself. IMHO the gEDA world could become promising if the leaders in that field would foray out of the "nerd corner" and into the Windows mainstream. I bought a decent compass/divider set while in college. It was probably something like$20, but well worth it -- compared to the $1 compasses I was able to draw much better circles. Oh, I've got a really nice set here but TSA so far considered those weapons. So before leaving I scope out a Walmart on the route from the airport to the client where they have the plastic versions for school kids.

The fully optioned version was/is about 20k$, but the base version was 1k$ a few years back.
There are other ways of getting around the price/performance issues with
the package, for instance Microwave Office used to cost considerably
less. Also all the synthesis tools in Eagleware usually have superior
tools with more functionallity from other vendors.
