Measurement of quartz crystal unit parameters - Measurement of drive level dependence (DLD) Ingestion-build-93833 particularly designers involved in the1 Scope This part of IEC 60444 applies to the measurements of drive level dependence (DLD) of quartz crystal units. Two test methods (A and C) and one referential method (B) are described. Method A, based on the network according to IEC 604441, can be used in the complete frequency range covered by this part of IEC 60444. Reference Method B, based on the network or reflection method according to IEC 604441, IEC 604445 or IEC 604448 can be used in the
