Material Sensing & Instrumentation
MSI Time-Domain-Reflectometry (TDR) Structural-Health Monitoring probes the structural health of a composite part by propagating a fast electrical pulse along a distributed linear sensor which has been fabricated directly in the laminate. The sensor is formed from the native graphite fibers already used in composite manufacture, and constitutes zero defect. Fibers are patterned into a microwave waveguide geometry, or transmission line, and interrogated by a rapid pulse as shown below. Structural faults along the line cause distortions in waveguide geometry, producing reflected pulses similar to radar. Cracking, delamination, disbonds, moisture penetration, marcelling, and strain are all detected by propagation delay, for sensor lengths up to several meters.

Moisture Resistance/ Humidity Test
-
This test is performed for evaluating the resistance of component parts and constituent materials to the deteriorative effects of the high-humidity and heat conditions typical of tropical environments. Most tropical degradation results directly or indirectly from absorption of moisture vapor, and from surface wetting. These phenomena produce many types of deterioration, including corrosion of metals; physical distortion and decomposition of organic materials; leaching out of constituent components of materials, and detrimental changes in electrical properties.

Amplifier, Switch and Test Box
CLIOQC Model V
-
The QCBOX Model 5 is a non-conventional unit designed to fulfil actual and future needs of an electro-acoustical analyzer like the CLIO system. It is USB linked to a PC and can be configured, with dedicated software controls, to assist frequency response and impedance measurements or to perform DC measurements. Using it for frequency response measurements acts as 50W power amplifier to drive the speaker or network under test while routing one-of-four inputs to the analyzer as well the current sensing output. The four inputs are able to provide a phantom power supply both for Audiomatica or general purpose microphones (0-24 V range, software controlled). Impedance measurements can be done either switching the D.U.T.’s load across the analyzer’s input or using a dedicated output, ISENSE, thus allowing impedance measurements in constant voltage mode as well voice coil current distortion analysis. An internal ADC measures the DC current into the voice coil. Thanks to an internal software controlled voltage generator the speaker can be driven with a superimposed DC voltage (±20V), allowing for measurements of large signal parameters. Two ADC converters with a ±2.5 V and ±5 V are available at inputs 3 and 4 to measure the displacement with a laser sensor or any other DC signal. A dedicated digital input handles an external foot pedal switch (or TTL signal) to be connected and triggers QC operations. A 6 bit output – 5 bit input TTL digital port is available to interface the QCBOX and driving software with external hardware (like turntables for example).The QCBOX Model 5 finds use both in laboratory for R&D applications and in production lines setups.

Audio Generator
AG-51
-
The AG-51 Audio Generator contains a low distortion 20 Hz to 200 kHz sine wave generator, an SMPTE standard intermodulation signal generator and a fixed frequency sine wave generator at 3.15 kHz for wow and flutter tests. Signal outputs are simultaneously available at levels of up to +20 dBm (equivalent sine wave power for complex signals) at separate left (L OUT) and right (R OUT) output connectors. Outputs may be selected for left (L) only, right (R) only, left and right in phase (L+R), and left and right in phase opposition (L-R). Fully balanced or unbalanced outputs at impedance levels 150 ohms or 600 ohms are front panel selectable. Three precision attenuators (10, 1.0 and 0.1 dB) provide a dynamic range of 99.9 dB in 0.1 dB steps. Attenuator dials display the output level directly in dBm in the 150 ohm source impedance configuration. Automatic output leveling circuitry with a built-in self-test feature provides a constant output level thereby eliminating the need for output metering. In the TEST mode the generator output level is reduced to zero, a useful feature during noise measurements.
