Can a moderator forward your access problem recount to ADI? If you agree, it had probably be better done by Andy or Tony, rather than me, because I might not understand the response (if any!).

.

?

I can't.

In LTspice, I click "Help-Get Support on EngineerZone" which opens in my browser Firefox.

It also fails in Chrome but somewhat differently.

When I click the "Ask a Question" button, the page goes blank and I see ez.analog.com followed by id.analog.com followed by ez.analog.com followed by id.analog.com for several minutes followed by some random page like:

?

How to Calculate the power factor in ADE7763

Which still leaves me no way to ask a question or make a feature request.

?

If I instead click "Log In" on the page I get:

That Was Unexpected

We apologize, but an unexpected issue prevented the page you requested from being available. We've logged the issue so the site administrator can resolve the problem.

I try "Log In" quite often so I've seen that message many times but no site administrator has ever resolved the problem.

?

I tried "Log In" on from my another workstation which does bring up a login page.

After logging in, the page blips and flips and blips until returning to with no indication that I have been logged in.

Clicking "Ask a Question" on that workstation did the same ez, id, ez, id dance to finally dump me into:

Do I need calibration circuit for AD9744 to produce high-precision output?

So, at this point, I will return to relearning Excel macro language.

I wrote Excel macro for a living some 15 years ago, so now I'm going to brush off some of my old macro work to see if I can relearn enough basic for applications to fully automate this -b batch process.

?

Thank you Tony.

?

All for now

Thank you John for your answer.
I will try a .meas for peak amplitude response.

Using a .MEAS statement, but it depends on how you define 'resonance', zero phase angle of the impedance, peak of the frequency response or something else.? The syntax for .MEAS is quite difficult to learn.

Hello,

Many thanks for your answers.
Using "table" solved my "problem"; i uploaded a screenshot with my
testing result.
A last(?) question, how can i measure the resonant frequency precisely ?
Regards,
Rudi

I will be doing seven or eight dozen -b test runs.

It would be soooo much easier to concatenate a hundred .mout files into one file.

Then read the one concatenated file into Excel, and then columnize by number of measurements, which is the same for each run, while stripping the *title line at the beginning of each set of measurements for the name of the test run.

?

Now, because LTspice is incapable, I will have to resort to macro programming in Excel to wade through all of the useless info at the beginning of each log file

to locate the measurement data.

?

I know, I know, I expect too much from a free program.

I don't know, but I'm not sure other (non-free) SPICEs provide much more. I may be biassed (of course I am), but I think LTspice's feature list is comparable to most non-free SPICEs, and the performance in most cases is better.

Is your aim to actually run in batch mode from the command line? If so, you might experiment whether output re-direction using the ">" of ">>"? generates any kind of output. The operator might not be exactly the same, I'm more used to using a BASH command line.

If nothing does what you want, you could do worse than make a feature request. The new team are receptive to ideas , but don't hold your breath. I've made several feature requests and a couple of them have been adopted. Others got an enthusiastic response without happening (yet). You don't ask, you don't get.

BTW, I'll let you know if find a simple way to get .MEAS data. I've modified the symbols and models, as you have done, to make the pin names consistent, so the analysis behaves the same way in batch mode as it does from schematic, and all the .MEAS actually work.

People say that the pin names don't matter, as long as the pin order is the same. Well, here's one scenario where that isn't true.

It depends on the circumstances. Sometimes the graph is unimportant if, for example, you're doing a Monte Carlo analysis. Then all you want is the exported data for post-processing. 10,000-20,000 steps is not an unreasonable step count for situations like that.

I will look this archive.

Rather than using multiple .STEPs, it is better to wrap the params within the same .STEP block, e.g.:

.STEP param Var1 1 10 1
+ param Var2 1 10 1
+ param Var3 list 1 2 5 10

This way, you can always be sure which order the levels operate, whereas if you use multiple .STEPs, the top one is whichever you added to the schematic first, because the order of execution is determined by the order they appear in the schematic .asc file.

You can use up 3 levels and a total of 65535 (2^16-1) combinations.

I changed the models concerned to alpha notation in order to match the alpha-based symbols and all is good.

But now my issue is with obtaining a .mout file.

If I do "File-Execute .Measure Script" from the plot window I get a .mout file.

But, if I add ".inc Original.meas" to a schematic, the measurements can be seen to run but, no .mout file is created.

?

This defeats the purpose of having a -b batch mode.

Does anyone know how to force LTspice to create that .mout file?

When I've previously used batch mode, I never thought about .mout files. I just read .MEAS results from the logfiles.

Yes, but it's not in the Help. Search the list archives for 'Stepping to the max.' /g/LTspice/files/z_yahoo/Tut/Stepping%20to%20the%20max

Hello,

A dumb question:

Is it possible to execute multiple .step commands each with one param or
one .step with multiple param
at the same time ?

Thank you in advance for an answer.

That is an awfully simple circuit to need a pre-made model. ?There are some good articles by Taylor, himself, that provide all the gory details.

True.? The Tayloe Detector model here is the one that I was interested in:
