AXTAL CONSULTING Test House
AXTAL CONSULTING is an independent test house for Frequency Control Products.
The company is privately owned by Bernd Neubig, a Physicist and Electronics enigneer with more than 40 years experience in the quartz crystal industry.
AXTAL CONSULTING's laboratory facility is located in Mosbach/South-West Germany.
It offers a broad range of services in the field of quartz crystal units, resonators, crystal oscillators, and crystal filters, some of them listed below:
- Failure Analysis of Crystals and its Oscillator Circuit. Determination of the required corrective actions
The most frequent causes of crystal failures are
► Insufficient safety margin ("oscillation allowance") of the oscillator stage for oscillation start-up
► Strong Drive Level Dependance ("DLD") of the crystals's resonance resistance
► Too low or excessive crystal drive level (crystal current or power)
► Frequency jumps (discontinuities) or stopping of oscillation in a certain temperature range due to so-called "Activity Dips" of "Frequency Dips" of the crystal
► Mismatch between the specified crystal load capacitance and the effective load conditions given by the oscillator circuit
- Optimization of the crystal application to assure high operational reliability
► Support in the design of the circuit of on-chip and discrete oscillators
► Worst-Case Analysis of the safety factor of oscillation start-up
► Testing of the crystals for Drive Level Dependency (DLD) and Activity Dips
► Measurement of crystal drive level in the circuit
► Determination of the working frequency and the equivalent load capacitance of the oscillator circuit
► Proposal for modification of the oscillator circuit in case of issue shown in above points
► Support in modification or setting up an appropriate crystal specification
- Testing of Quartz Crystals, ceramic resonators, Oscillators, SAW devices and Filter
► Electrical testing of crystals and resonators according to IEC 60122, IEC 60444 and MIL-PRF-3098
► Electrical testing of oscillators according to IEC 60679 and MIL-PRF-55310
► Electrical testing of crystal filters according to IEC 60368
► Electrical testing of SAW Devices according to IEC61019 (SAW resonators) and IEC 60862(SAW filters)
► Environmental testing according to IEC 60068, AEC-Q, MIL-STD-202, MIL-STD-883 and others
► Testing according to ESA and other Space specifications
► Testing to customer specifications
- Screening Tests and Component Selection Tests
► For High Reliability applications such as Downhole, Military, Aerospace and Space
► As immediate measure in case of failures, before the corrective actions are effective
- Qualification Tests for Commercial, Automotive, MIL, Aerospace and Space
► Capability approval test procedures
► Qualification approval test procedures
► For crystals and resonators according to IEC 60122, IEC 60444 and MIL-PRF-3098

► For crystal filters according to IEC 60368
► For SAW Devices according to IEC61019(SAW resonators) and IEC 60862 (SAW filters)
► Environmental testing according to IEC 60068, AEC-Q, MIL-STD-202, MIL-STD-883 and others
► According to ESA and other Space specifications
► Qualification testing to customer specifications (also shared test strategies)
