scope:
This part of IEC 444 applies to the measurements of drive level dependence (DLD) of quartz crystal units. Two test methods are described. Method A, based on the pi-network method according to IEC 444-1, can be used in the complete frequency range covered by this part of IEC 444. Method B, an oscillator method, is suitable for measurements of fundamental mode crystal units in larger quantities with fixed conditions.
