Silicon crystals are used in RADAR mixer and detector stages. Using an ohmmeter, how might a crystal be checked to determine if it is functional?
Its resistance should be the same in both directions.
Its resistance should be low in one direction and high in the opposite direction.
Its resistance cannot be checked with a dc ohmmeter because the crystal acts as a rectifier.
It would be more appropriate to use a VTVM and measure the voltage drop across the crystal.
