Why some brands don't do LCR meters?

Martin72:
That can only speak for Tonghui in terms of quality.

MathWizard:
You know how there's the FY6900 100MHz Signal generator, it's even in a case like big name versions.

Does any body make cheap LCR or Impedance analyzer versions up to even 50MHz, that are in a box, and are not $20 ebay sig gen or LCR tester quality, but upto the FY6900 level ?

For hobby RF projects, I would want to test a part, at the intended frequency, or close to it, quicker than using a scope and AWG, etc. Or sweep the frequency too and get a plot of something, and even upload it to PC.

The NanoVNA ? LCR meters rarely exceed 1Mhz. Normally with higher frequencies, people switch to a VNA.

MathWizard:
I have my eye on them too, I wish they were in a box. So they are a VNA, I have to research all this more because I can't remember if the NanoVNA needs an external signal source, or if it makes it's own. I'm pretty sure good SA's and VNA's have a good SG inside too.

I better look up Impedance analyzer's for sale and read their spec's, see what they do.


As a bench LCR meter, I wonder if something like this really has the mili-ohm spec's listed. I'd like something like these too, IF you could set the frequency to anything you wanted up to the max 100kHz. But yeah I want upto AM radio range at least.

No, it's self contain. You can even get one of those cheap adapter board to quickly put different components in different configurations.
