PC-100 Precision Quartz Crystal Stability Test Set

Data on the long term frequency stability of quartz crystals has always been a specification that most manufacturers have been unable to provide due to the lack of a good testing system to measure the long term aging of quartz crystals. The PC-100 frequency stability tester now fills this need.

Benefits of Obtaining Aging Data

When long term aging is measured and statistically analyzed, it proves to be a valuable tool to determine the crystal's overall manufactured quality. It is truly a bottom line test. The test becomes the final evaluation for plating and bonding integrity, the mounting stresses present, quality of the quartz material, holder leak rate, and overall internal cleanliness. Many crystal manufacturers rely soley on their customers to tell them how well their crystals are performing for long term stability. In many cases, manufactureres don't know how well their crystals perform and tend to underestimate their ability to produce low aging crystals. This results in a loss of sales.

Testing for Long Term Aging

Several conditions must be present while measuring frequency aging of individual crystals. These include:

A constant long term temperature environment.
A constant crystal drive level.
An undisturbed aging fixture with no physical movement of the crystal.
If an oscillator is used, it must have known aging properties and be electrically very stable.

Testing for long term aging is a very precise and demanding test. The PC-100 has been designed to meet all of the above requirements.

As a Crystal Manufacturer

Accurate aging on your crystal products for the sales and engineering staff
In the past, the end users knew more about the aging performance of your crystal products than you did. Now the PC-100 can supply this crucial data for your customers before they buy.
A cost-payback is received by the ability of optionally charging for aging characteristics on crucial crystal requirements.

Benefits to the Manufacturer/Crystal End User

Customer will be able to know what they are receiving from the crystal manufacturer as to aging quality.
Customer can test the products from several manufacturers and purchase from those that have the best aging quality.
Able to predict frequency aging and specify crystals which best fit the life of the product.
