content: I'm looking for a fluke PM6306 or other 1Mhz LCR meter. Recommendations welcome.Idealy I'd do frequency sweeps to measure inductance & Q factor vs frequency

content: Just to be aware that in order to do the sweep, you need the original software, yes, I own that meter.But .. there is an alternative, good one imho, made by member thru DIY , check this out ->https://www.eevblog.com/forum/projects/impedance-analyzer-build-and-experiments/

content: I'm now looking at a solution based on a analog discovery 2:https://youtu.be/qPdLHJ2zEsECan go up to 20Mhz and is about $500That seems to be the best option for nowI got about $1000 budgetI want to measure at up to 500khzI would like to get the best possible accuracy when measuring a 100uh inductors Q factor at 100khz

content: I've got one of these from Rosenkranz in Darmstadt / Germany:https://www.newtons4th.com/wp-content/uploads/2010/03/PSM2200-User-Manual-v3_16.pdfDoes RLC and swept RLC measurements up to 2.4MHz afair, accuracy might not be as good as a dedicated RLC meter.You'd have to DIY the adaptor for RLC measurement, but it can be as simple as three BNC plugs and a resistor.

content: The cleverscope CS448 seems like a really good piece of equipment for this:https://cleverscope.com/products/CS448It's slightly more expensive though

content: You don't need a CS448 for impedance measurements up to 1MHz, a CS320 or 328 does it (I have one).Give some thought to fixtures before leaping.Cleverscope promised a software upgrade for the FRA/Impedance functions a couple years ago but never delivered. The existing system is a mess, IMO. I don't use it.A used HP 4277A would do the job.

content: Quote from: precaud on September 14, 2020, 01:31:24 pmI was thinking about getting this scope either way for gan half bridge measurements.But seems like I'll get an analog discovery first while I'm still working on the stuff I need the impedance analyzer for , this way cleverscope has some time to get their act together before I buy their $9600 scope

content: I sold a PM6306 with the original software about 6 month ago.Now I have only two left.Once in a while they show up used for Euro 2000 but that price it not real anymore.This Fluke PM6306 was also sold under the brand name of Wayne Kerr, Model 4265

content: Quote from: Elmar on September 14, 2020, 09:56:44 amHi Elmar,It completely depends on the type of inductor you want to test and the level of accuracy you are looking for. When it comes to the Fluke PM6306, it gives a measurement accuracy of 0.1% * (f/50 kHz) +/- 1 digit for frequencies greater than 50 kHz.You can also checkother LCR meterssuch as Keysight E4980A with +/- 0.05% accuracy and high measurement repeatability at varying impedance. I hope this helps.
