Crystal Measuring Adapter (CMA) for NanoVNA PCB for the Crystal Measuring Adapter (CMA) for NanoVNA project. PCB Euro 7,50 7  

nanovna_xtal_pcb 

nanovna_xtal_024  

 Note : picture is assembly example, PCB is sold without headers, small crystal header, toroids,
and edge connectors, but comes with the 4 SMD load resistors pre-soldered and 2 SMD 0 ohm resistors
for the attenuator sections (0dB).

On request I can add 3, 6, 10, 16 of 20dB attenuator on input or output (additional euro 1,50 / section).
For example when you have a NanoVNA H4 with a output of +6dBm a 16dB attenuator
would required to have a -10dBm max drive on the crystal.
