I mean fast ADC and DDS chips are so much cheaper these days. Hell you can buy a 6ghz 2 port VNA for 600 bucks, but no one makes a 100mhz Z/LCR meter for under a grand..

Do you mean 100kHz? a 30MHz LCR will cost you around $20,000.

rwgast_lowlevellogicdesin:
No i mean 100mhz, my point is there is no reason a fast lcr meter is so much when a 6ghz VNA can be had realtively cheaply.

Show me a 100MHz LCR for $1000 and I'll buy it. Also try looking at the hardware that goes into making either of those devices, you're comparing apples and Toyotas. I'm with you though, I wish a quality high frequency LCR meter existed for a reasonable price.

rwgast_lowlevellogicdesin:
If i were better at math i would take the project on.. it seems to me you could build one with a fast ADC, a Zynq, and some hi speed opamps. Thats what 300 in parts at the higher end...

Milli Hertz ?

Sorry but you are beyond help if you cannot make the effort to use the correct denominators on a technical forum.
What example are you setting for others ? :-//

I'm outta here.....
