One should consider measuring Capacitor ESR at or near the frequency of intended use for the best results within a circuit. If this isn't known beforehand, or for general purpose use, Capacitor characterizing over a broad frequency range and creating a plot of ESR vs frequency seems worthwhile.

Also note that certain type capacitors (high dielectric ceramic types) have widely varying parameters with applied voltage, temperature and age which creates a difficult and time consuming effort to characterize.

Best,

I used the exported data from the "LCR Meter Sample Application" to create the Excel spreadsheet, and then the data exported directly from the IM3570 to create spreadsheet v2. The data appears the same on the chart, despite being separate test runs.

Try plotting with Log Log scales, this will show Z better over a wide frequency range.

Best,

That's super easy to mess with in the spreadsheet.

Nice plot  :-+

What is the point of going from 4 BNCs on the instrument, through a box and cable to another box with 4 SMA?, and then out to the probes?  Why not directly connect a set of probes to the instrument BNC?  What is the point of the extra boxes and cables in the signal path here?  I would understand if the probes and BNC box was one unit, but separate probes with SMAs?  The frequency only goes to 5MHz.  BNC is more than fine for that.
