Hi Dr. Mauro Casaroli
I am Allen from Conectmed,we serve medical equipment and accessories manuafcturer and provide them cale,including the Doppler cord
different brands doppler manufacturer use different structure cable ,it seems does not have an industry standard.we have several doppler probe manufacturer customers,we see it has many types of dopper range 3MHZ to 8 MHZ,but the cable speficification is the same.
Following is a webpage for the doppler cord we made for them.,we can also custom according to customers, special spec.
