Measuring output impedance in LTSpice

Sorry, I misunderstood - I thought there was supposed to be an attachment in the message I replied too...

All the various methods tried here seem to have worked for me so far.q

Oh really? Another guy on the European NG, quote "Dein angehängtes Beispiel konnte ich problemlos in LTSPICE laden und simulieren." Literal translation: I could load and simulate your attached example in LTSpice without problems.

He uses Seamonkey (also a Mozilla product), not sure why they picked that strange name. Even if this pains you, it seems Agent is not the standard. Or at least not anymore.

I can launch your form of "attachment" by right clicking in the message, open attachment directory, then click on your file name. IF you named it in your message I can find it easily. You didn't name it at the break-point in your message, but I saw it in the directory since it was in German (?)

Hobbs' "proper" method, simply right click the attachment name. Done!

Standard, smandard. Blather all you want. The question wasn't whether it was launchable eventually. It was about EASE! Your way is the crude way. (Maybe that's your "standard" ;-) ...Jim Thompson

Me neither. But I just opened the phase shift oscillator file (in another thread) from Warren from his attachment. The difference I saw in the process: when I double clicked on Warren's attachment, the window that opened had LT spice (default) in the "open with" box. With Joerg's or Phil's, the open with box had txtfile not LT Spice. I had to select the launching app, and I chose scad3.

Looking at the Content-Type header info in their posts, I see what may be a clue to the cause of the problem. In the following order: Warren, then Joerg, then Phil content type information. Content-Type: application/octet-stream; name="Phase_Shift_Osc.asc"

Content-Type: multipart/mixed; boundary="------------070604080302010003040205"

Content-Type: multipart/mixed; boundary="------------070304010100010408010508"

The line wrap occurred when I pasted the above here - there is no wrap in the headers.

In my case, with Joerg's attachment, I do not get filename.asc.txt The .txt is not appended, as it is in your case. I get LTspice IV - [Diodenpulser_4.asc-4]

So we both get failures, but even the failure mode is different.

Have you set up the default program for *.asc files to be scad3(4).exe?

With agent, if I right-click the filename, I get a menu of choices... choose the first, which is "launch". ...Jim Thompson

I found a setting for 'Toggle Attachment Pane' that will let me right click and save it, but it screws up other messages. I'm using Netscape

Well, I can right-click the attached file name and get it to save in my directory of choice which LTSpice knows, and it works fine. I was just hoping I could find a way to get it to launch. TB does not have a way to specify launch progs, AFAIK.

My excuse? It was before I met unix, then Linux, because once I met a real OS, first question was 'how can I do this at home?' :) Been running at least two PCs on localnet since, taking the best of both worlds, which for me is windows desktop over Linux networking. The software I enjoy tinkering is system stuff and the odd web page (mostly

As long as one's time is not counted.

Only times I modified some apps was actually binary mods to make it work better, I remember hacking z80 dasm to increase table size back in the '80s, and a card solitaire game I had to change name of their .dll to avoid a clash, in the '90s.

Plus dongle disconnection from a an expensive app in the '80s ;) Sped it up no end by stopping a silly conversation with said dongle, 'yes, it's here'... every time one hit main menu.

Source is too easy in one sense, but may require lots of poking around. Gives more confidence that it's available. My name's in the linux kernel for minor work, but that project moves way too fast for me to keep up for any length of time.

Yeah, I grabbed the tarball, it GUI? My linux boxes not really setup for GUI at the moment, I use PuTTY terminals, sometimes lots of them. The old idea, GUI is there simply to allow more terminals on the screen! :)

Maybe I should try SeaMonkey, it's the modern incarnation of the old Netscape Communicator suite, browser plus email and news. Big, slow and cumbersome, still the favourite of many, Slackware still include it at last look.

Of course Netscape's history was a browser that simply fell over on certain web content, unix version just as often as the windows one. It was browser of choice for unix, and in 2001/2 I did a lot of cross-browser javascript compatibility design, result of which was an online info-sys that renders properly on modern browsers, yet is unmaintained for the last decade. No SQL injection attacks. I drift, oops. More coffee!

Because early days Netscape Communicator did it all. Netscape was quite good during the browser wars but MSFT went out of their way to kill it, first a free browser to cut Netscape's income, then the standards battle to confuse web page authors. This was during the 1990s. Netscape went broke and open-sourced their code, resulting in Firefox, Thunderbird and SeaMonkey -- that's my memory of the events ;)

PGP routinely uses .asc (ascii-armoured) for encrypted binary files. Your attachment showed up as an attachment in my Thunderbird (Linux) and would have opened in LTSpice with WINE if I had configured that. Obviously I don't want to launch PGP files into Spice :)

No. I don't recall ever setting that up as the default for .asc - but I may have, long ago. Currently, in Thunderbird's tools->Options->Attachments dropdown there's a place where the association could be made, but its greyed out.

There may be a way to "un-grey-out" the thing, or some other way to get Thunderbird to do it that I don't know.

But Thunderbird does use LT spice as the default when it recognizes that the attachment is a file with a .asc extension. It opens the attachment to Warren's file with LT spice, so my suspicion is that Thunderbird is not recognizing Phil's or Joerg's attachments as .asc. I posted one as a test, and Thunderbird didn't recognize it, either. For now, the best I can do is save the attachment to disk. It opens fine from that.

True, but it is time spend well, you actually create and learn something, unlike re-installing MS windows for the nnn's time, then the only reward is irritation, and the feeling you should be doing something else than looking at those MS silly commercials while it installs. So I burned the xp disk :-)

There is a z80 disassembler I wrote on my site, command line, C source, Linux: It is a very good disassembler, you can re-assemble the output no problem and than the binary will be identical.

Yep, I did some audio driver mod for 48000 long time ago, do not think it is the main tree, OSS went out, now it is all ALSA.

It is GUI, it was written initially as an attempt to have 'Free Agent' for Linux, so the look and feel, at least from the basic GUI, is similar. The original name was 'Secret Agent', sort of a word play to 'Free Agent'. Nonetheless it has some special crypto in it.

GUI

You will need the xforms development package installed for it to compile.

Yes wget is cool.

Retired, but still active. I am in the process of setting up my new physics electronics lab, with some fascinating experiments planned, got an other part up and running yesterday. These days I am into superconductors, gravity, and time warps. And the theoretical part that comes with the experiments too, just like every bit is falling into place. A welcome escape from twenty first century pseudo science. But it may hit hard on those who are believers in that. Reality rules, as always.

Also, the database is memory resident, so casual enquiries don't suffer a penalty for searching a disk datafile file. Suits a log analysis app I have running most of the time.

Fine, I prefer to not burn bridges, though I have to be paid to write windows code again, I decided that after looking at setting up their web server, no thanks ;)

That's what Jim doesn't want to believe :-)

Yes, that is the problem with suffixes as there are only three letters but a bazillion programs. There isn't (yet) a conditional association. Like "consider *.asc an LTSpice file if in a news group but PGP if in email".

You can just download that database, I have it in my home dir, an older version I am sure. Where it will go with IPV6 I dunno, you cannot have that many entries in a small database.

Yes, that is right, it is godaddy, they run secureserver, and secureserver.net has a server in europe, that happens to be in Amsterdam. I know it is Amsterdam because it has 020 area phone code for their helpdesk link. But for help I communicate with the US base. That IP runs multiple servers for many users, I am just in a sub directory. So it is a fixed IP, but shared.

Linux will cache it if it is often used, but I only very occasionally look up some IP. Linux made me lose fear for disk I/O years ago, I use files for everything, all will be cached.

I have written windows code for my job, never found it that great, Visual studio ... I do not see MS products as bridges, more as a mine field ;-).

than the binary will be identical.

I dunno, there are some really complex chips that use z80 based code, mainly from the east, used in embedded systems. Z80 was (or is) quite efficient code wise.
