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.

Launch Fiber Box
-
OTDR measuring devices are used in various ways in fibre optic technology. They enable extensive characterisation of existing fibre optic cabling networks. The use of launch and receive fibres is advantageous when it comes to ensuring precise results evaluations. With bidirectional backscatter measurements with launch and receive fibres, the attenuation values of the first and last plug-in connection can be determined precisely by averaging and device dead zones can be avoided. Measuring device manufacturers recommend different lengths of launch and receives fibres to avoid “phantom reflections”. These launch and receive fibres are also subject to measuring equipment monitoring and should regularly undergo revision in accordance with the OTDR measuring devices. A good measurement result depends on the state and quality of the measuring equipment used. Diamond offers various types of launch and receive fibres, one with standard telecommunications connectors and the other with an outdoor connector for harsh environments.
