In this video I look at how sets of parameters can be stepped at the same time using the .step command together with the table function. Its quite a simple implementation that can be used to go trough multiple parameters at the same time.

I think you’re my new favourite electronics RUclipsr, because your voice and attitude is so professional and unique. God bless you sir.
You are so underrated! I was actually wondering if something like this existed but didn't find much. Thank's so much, all that I know about ltspice I owe to you
Using the voltages as direct readouts for the index variables in the first sim is a nice teaching technique. I'll have to keep that one in my back pocket. Thanks for introducing it to us!
One detail worthy mentioning. This docs is inside menu -> help -> help topics, or simply press F1. Then, LTspice XVII -> LTspice(R) -> Dot Commands. This Dot Commands section maybe the most important as I would say, every user has to know how to find this.
Always appreciate new videos with this tool.
Great Video, I am currently learning ltspice and your videos have been a great help
very good video. such a useful feature man simulation is such a time saver when the tool used is understood.
Great work, as-usual!
Thank you for showing this technique in LTspice. It would be great to see an explanation of the "measure" statements in LTspice. I have a hard time understanding their syntax. In recent versions, there is a GUI implemented to write them but that does not give the entire flexibility and power of the measure statements.
Nice one! Another advantage of 'scripting' these circuit variants is that it avoids problems in copy/paste actions where you accidentally missed a change in one of your simulations. Makes things much more reliable and reproducible.
To be honest, if I just want to change component values, this method is ok; but the copy/paste method can be far more useful when changing interconnections or adding different components.
Huge thanks
Great video!
Thank you so much.
Analog should hire you :)
Shouldn't be the .step param n 1 2 3 instead of 1 3 1 at 4:20?
Hi FesZ Electronics: What is the purpose of Pgood connexion ?. Datasheet shows typical application without Pgood.
In general Pgood, PG, or "power good" is an open drain output that stays high only if the power supply is within ~5% of the nominal voltage (exact % differs from IC to IC). The common use case is to link this pin to a microcontrollers reset so that the uC is allowed to function only after the voltage stabilizes. This is to prevent unexpected behaviors during low voltage supply.
@@FesZElectronics Ok and in your simulation R5 could be removed and will work without problems.
Of course. I didn't really bother to remove unwanted components from the schematic, I just took the default test fixture that LT provides.
Hey FresZ, Do you have a doctoral title? If not any known university should give it to you ;-)
Alot going on haha big headache lol
