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

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. |

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. |

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... |

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..... |
