LCR Meter Plot Software

[mawyatt]

super inspired by mikes idea about a curve tracer for the LRC instrument TH2830,
we had a great day making a little java version
it run in a random browser and any platform
no sw install needed, no skils needed, it is so far just two txt files in a folder, one is a HTML file
and it also works perfectly fine on a PC
anyone like to hear more about this ?

Yes, definitely

here you go mike.. and anyone else with a TH2830 :-)

webx dot dk / th2830 dot zip

unpack the two txt files into folder of you own free choise
open the htm file
com port is connected to your th2830, i use 9600 baud, so that is what it defaults too,
also setup : avarage 1, speed medium.
this is first demo version,
so far you just setup the type of measurement on your th2830 hit lock to get back to local mode
the software take both measurements selected on the th2830 and perform auto scale trace
you can zoom and move and all that, add peaks and save csv file too,

ideas for next version : let the sw handle all the measurement modes,
and scale to pF nF uF and such correctly, that could be cool
so far the sw readout the values as they are delivered from th2830
that means capacitance is in Farads :-) and that is a little bit ignoring,
but there is a comment line,  where you can edit a multiplier, enable that to make it read out in uF
as explained in the txt file

Thomas,

Can you make this active again?

Not sure if we've looked at your version, memory is going fast!!

Thanks

Does this only work on USB/serial, or did you also get it to work over ethernet?

Thanks,
Josh

RS232 to USB.

We've updated the IM3536 plotting routines, cleaning up some things and adding the ability to handle Engineering Input notation like k (kHz) and M (MHz).

Here's a few plots of a 32.786KHz Crystal using the Custom Split-Kelvin SMD LCR Fixture with the IM3536. These are with 1Hz steps with Linear Frequency Plots.

Note how the Phase transitions between -90 degrees Capacitive to +90 degrees Inductive and back to -90 degrees Capacitive. This occurs as the Frequency sweeps up to Series Resonance, then to Parallel Resonance, and past Parallel Resonance. Also note how RS (Effective Series Resistance) peaks at Parallel Resonance.

Will include the TH2830 version if anyone is interested (needs some testing tho).

That looks great!
