8330a Radiant Flux Meter

Mellon Optical measurement is one of the oldest and most fundamental areas of science, yet it's still one of the least mature. Optical energy is generally considered to be the portion of the electromagnetic spectrum between microwave and x-ray frequencies. Measurements in this region are a separate area of science because optical sources, detectors, and techniques differ markedly from those used in the microwave or x-ray regions of the spectrum. Within the...

Digital Testing versus Digital Testing

There's more than one kind of digital testing. The two basic kinds are functional testing and parameter testing. Functional testing can be divided into static functional testing and clocked functional testing. Static functional testing, sometimes called truth-table testing, is used to verify the logic of the unit under test. Patterns of logical 1's and O's of appropriate voltage levels are supplied to the input pins of the unit under test and its output patterns are compared with the expected...

Hewlett-Packard 9500 series automatic test systems are computerized systems for testing electronic devices. A 9500 system is a stimulus response test system it has power supplies and signal generators to provide input stimuli to the device under test, and it has measuring instruments to monitor the outputs produced by the device in response to the inputs. Everything is controlled by the computer, which is programmed in a version of the BASIC language called ATS BASIC* it's an interactive,...
