Meeting Specific Test Needs Without Purchasing Costly Test Equipment

"Viable Solutions to Customized Product Testing"
Patrick Beaver
Engineering Manager
Digalog Systems, Inc.

From design validation to the production floor to on-site diagnostics, testing is a critical component in the product development process - which basically involves identifying potential problems in order to address and resolve them. Finding a piece of test equipment that will address all of a product's testing needs, however, is a dilemma that frequently leads to creating a custom, product-specification defined, rack-and-stack. This often results in a solution that resembles a "hot mock-up" or "plug-it-in-and-try-it method" that's expensive to maintain.

Signal Switching in Modern Test Systems

"Making The Switch"
Michael Moran
Product & Support Technologist
Digalog Systems, Inc.

Test system designers are vitally concerned with connecting signals between their instrumentation and the products under test. These connections have to be reliable and inexpensive, to occupy minimal space in the system chassis, and to satisfy the need for routing and re-routing scarce resources as quickly as possible. To meet this need Digalog created the DigESwitch product line, a series of 2U rack-mount switching solutions available in single-ended matrix, and differential mux configurations.

Signal generation and measurement resources can be expensive,

Functional Tests

Often, there is a temptation to start writing test code before there are adequate test and process specifications, leading some to ask, "Why do we not have time to do it right, but we have time to do it over?" While there is a legitimate need to complete test projects quickly, a more accurate and less costly way to achieve the same goal is to start writing the test and process specifications early-even while the product is being developed.

Cost Effective Testing Technologies

"Bridging the Gap Between Instruments And Devices Under Test"
Patrick Beaver
Digalog Systems, Inc.

Price competition is more evident in automotive electronics than in any other industry. To remain competitive, new cost-effective technologies must be implemented in the design and manufacture of automotive electronic products. As a result, automotive electronics testing must be equally responsive by applying new test and measurement methodologies that accurately and quickly accommodate validation and functional testing.
