3D Inspection Service
-
The reference data may come in the form of a table, with values at specific points or features, a cad model, or 3d scan. 3D inspection services may require datum measurements, where the part to be inspected is located in a fixture that is specifically designed to orient the part by an ordered method. In some cases, the part may have features that are designed specifically to be referenced by datums, if no functional feature of the part provides a clear reference.

High Accuracy AC Reference Source
515
-
Clarke-Hess Communications Research
The Model 515 High Accuracy AC Reference Generator fills a need for a relatively low cost and practical solution for supplying a reference excitation to typical LVDT and Synchro/Resolver transducers. The Model 515 has built-in load sensing which, in effect, yields "zero" output impedance and virtually eliminates the effects of fluctuating output loads. With up to 15 VA of output into loads with as much as 80 of phase shift, the Model 515 is ideally suited to driving inductive loads.

Manual Testing Services
-
Production teams often refer to automation testing like it’s the holy grail. But when it comes to user experience, there’s no replacement for the human eye. While automated tests focus on repetitive tasks, manual QA testers come up with creative use cases and provide a lot more value. Very often, our recommendations helped improve the products and even lead them in new, more successful directions.

Frequency Response Analyzers
-
Frequency Response Analysis (also referred to as Transfer Function Analysis) measures the output spectrum of a system relative to a stimulus, and is used to characterize the dynamics of the system under test. The technique measures the magnitude and phase relationship between output and input waveforms as a function of frequency. The input signals may be from a wide range of sensors including acoustic (microphones/sonar), mechanical (accelerometers/displacement transducers), optical (photodetectors), and electrical (amplifiers).

Active Filter
J2190A
-
The J2190A active filter presents a high impedance (approximately 150kOhms) minimizing the loading of the circuit being tested. The output impedance is 50 Ohms allowing low noise coaxial connections to all typical test equipment. The 0.1Hz-10Hz noise band is common for opamp measurements, voltage regulators and voltage references. Many application notes offer schematics of such a filter for test purposes. An engineer’s time is much too valuable to be spent building test equipment. We have created a 4th order high pass and 4th order low pass filter with an optimally flat response and 0dB gain. Additional filters can be cascaded for even sharper cutoff.
