Mid-range price LCR meter ?

Frequency requirements depend on the DUT. Some LCR's go up to 50MHz, which I guess you could say is relatively low frequencies compared to other devices. I have no idea what makes them so expensive; but I would guess it's the lack of competition.

If you look at the datasheets for specific components, you'll see that spec values are often measured in the MHz range.

That might give an idea why meters are exploding in price with every Mhz decade of measurement frequency:

KungFuJosh:
I dunno, that seems like a lot of reading might be involved. 😉

Martin72:
Up to 100khz this is still manageable and relatively inexpensive to realize, from Mhz it becomes more complex and therefore naturally more expensive.
That's more or less what it says. ;)

That's what I assumed it would say. 😉

However, I would bet up to $3.50 that the Instek 8200 series are all the same HW except for some FW crippling. Based on the logic of that doc, it must cost Instek more across the spectrum to make them.
