Measuring output impedance in LTSpice

"One" guy using your same tool can read it ?:-) Did he launch into LTspice FROM the message? Hobbs' post worked, your's didn't.

Whatever you think you did... "inline" is NOT an attachment in most people's world. ...Jim Thompson

Right now my Thunderbird wants to open it into the PDF reader for some reason. Haven't figured that out yet but not so important. I will have to find out how to add the *.asc file type in there because right now it won't let me. I can launch it by hand though, works fine. Even if you say it shouldn't because it doesn't over there in Phoenix :-)

BTW, Phil's attachment and mine behave in exactly the same way on this here computation machine, as attachments.

As I said before, it shows inline _and_ as an attachment. I have set my software that way because it's also my email program. That way I can quickly see scope shots from my clients right inside the emails and also as attachments for file storage.

Tell me, if it was only inline as you claim, how could it be that if I click on this attachment and save it as a file it saves correctly? Do you really think a li'l gnome is built into Thunderbird that automagically detects which lines are SPICE and which ones are not? Would it automatically remove lines that have the words merlot, barbecue or global warming in there?

Sure, it's important. You didn't "attach" in the functional sense of the word.

Wonderful ;-) Did it launch into LTspice? No? Hobbs' did, and that's the whole point, view in LTspice without intermediary steps.

Right click and saving ain't the same as "launch".

There's a little "gnome" built into Agent that knows how to launch a schematic with its parent application.

Cheap is as cheap does ;-)

Eudora is an E-mail client.

Agent is a newsreader client.

Thunderbird is a hack ;-) ...Jim Thompson

What is the functional sense of the word? To me an attachment is an attachment is an attachment. IOW a file stuck to a message, and that's how it shows up.

I asked the German engineer, in his Thunderbird he can set file associations so the desired program launches. Turns out the config menus on his TB are totally different, he has a file association table just like Windows does. My TB doesn't.

It is. You only need to set the file associations right. And somehow my Thunderbird can't while the German one can. Guess I may have to upgrade.

Same in Thunderbird. Except the configuration in mine is a bit recalcitrant.

Nope. It's a rather fine piece of software. I prefer to have the same program for news and email.

confidential,

When _you_ can "launch" an attachment from within Thunderbird, come back and tell me about it. Until then... don't tell me about "someone else" being successful :-) ...Jim Thompson

Might be a while. I am in the middle of two major projects so I can't possibly upgrade Thunderbird right not (the German enineer's version is newer). Fact is, I no longer need to copy and paste and that's what this exercise was about. I can take the attached file "as is" and launch it in LTSpice, done it with Phil's as well as mine. Worked. Sorry, can't help it if Agent can't.

You didn't launch it from _within_ your reader.

Agent does that just fine.

I'm sorry you don't understand, but I give up. ...Jim Thompson

LTspice users should be able to launch the attached schematic directly from their reader.

Please report back success/failure and reader-type/version.

Thanks! ...Jim Thompson

Ok, tried it on the Samsung netbook which has a (only slightly) newer TB version. It does launch straight into LTSpice. At the first instance it needed to be told which program to pick, and from then on it "knew". Happy now?

But didn't you say Agent did not recognize my attachment? Then it did not do fine.

There's nothing to understand other than that the attachment does come through as an attachment. And it did.

It didn't show as an attachment here... just contained in the body.

Try it again from your newer machine. ...Jim Thompson

That's just something random that had been posted to SED in the past... not my creation. I only use LTspice as a netlist ingester, and reader for questions asked here :-) ...Jim Thompson

After having used PSpice for over a week now I must said that I'll be glad when I can return to LTSpice. The speed differences I see are immense. And I like the backend better, mostly the display options.

You like the LTspice backend better? For presentations? You certainly are a strange fellow ;-)

LTspice is certainly speedier for single cells, but the LTspice Yahoo list discussions suggest some real issues with trying to do hierarchical calls for stuff not in the same directory. ...Jim Thompson

A guy on a LinkedIn forum called me a Luddite for prefering NNTP servers over pretty much any other forum. So he went ahead and made a fancy web portal. As predicted the discussions in the forums are rather anemic :-)

I find LTSpice makes for very nice presentations.

Yes, it sure does have its limits. I don't think there's much motivation for LTC to compete with the "big iron" because it is mainly intended to aid in the design of switch mode converters. And there it's blazingly fast. I do a lot of those.

Nah, just the usual LTSpice thing--the transistors and resistors are impossibly huge, so if you want the schematic to fit on one screen, you wind up with an ugly layout. (Other folks are probably a lot more artistic than I am.)

No, Agent's been around for a long time, that's all ;)

Yup, in the spirit of the sender, the inline 'attachment' worked fine!

Agent correctly showed the demarcation, but since there was no filename given, agent can't save it. That's how inline text attachments work, and they're preferred in some places.

His was really truly and attachment, with a filename.

But you're being touch too sensitive or pedantic going on about trying to avoid a simple copy/paste/rename operation to recreate a text file.

FWIW it seems to be a distinct "inline" section. In GNUS it initially shows as normal inline text, but I can save it as a distinct attachment which I can then drag-and-drop fine into LTSpice. It does save a few steps over the copy-paste method, I prefer it as long as we don't hear reports of these not getting through news servers.

On a sunny day (Sun, 03 Apr 2011 17:33:56 -0700) it happened Joerg wrote in :

The danger there is that if somebody posts a text plain document that is NOT intended for LTspice it will start LTspice anyways. 'Text plain' is just that, ASCII text, and should go to an ASCII editor or display. So we need a new mime type, 'text LTspice'.

The rest is just undefined.
