Hi,

  I would like to measure magnitude and phase of a DF Receiver using VNA. DF Receiver is taking RF input ( Range: 20 MHz to 1 GHz) and gives IF Output at 70 MHz. It has internal LO. I have read some literature about frequency translating device test using FOM Option. How can i test this device without having External LO ?
 
Can anyone tell me the procedure to test this particular device ?

Regards,
Ranjan
