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.

Erbium Doped Fiber Amplifier
EDFA
-
EDFAs are based on the light amplification in erbium-doped fiber, which are optically pumped by means of 980 nm or 1480 nm light sources. In this way, the light of a larger wavelength within the C or L band applied to the input of the amplifier is amplified, thus widening the range of optical communication links. EDFAs typically operate in saturation and the average signal power determines the average gain. The dynamics of EDFA are unaffected by the sequence and dynamics of a digital signal or channel interaction in DWDM systems. As a result, multiple channels can be bundled within the total erbium spectral amplification bandwidth. However, the total average output power in both cases is determined by the saturation power of the specific EDFA.

Fully Differential Amplifiers
-
Differential amplifiers allow the process of single-ended input to complementary differential outputs or differential inputs to differential outputs. These amplifiers feature two separate feedback loops to control the differential and common-mode output voltages. Analog Devices fully differential amplifiers are configured with a VOCM pin, which can be easily adjusted for setting output common-mode voltage. This provides a convenient solution when interfacing with analog-to-digital converters (ADCs). ADI also offers a series of differential receiver products that convert differential input signals to single ended output.

HF Amplifier
Prometheus
-
The design of the Prometheus is the result of over 10,000 hours of research and development, encompassing hundreds of hours of mathematical analysis, computer simulation and modeling, and numerous prototypes and experiments spanning over a five year period. The result is a rugged, commercial quality amplifier designed to run cool under 1500W continuous SSB, CW or RTTY, with special ferrite transformers and combiners designed for full power operation even on 160 meters. Although our custom transformers are more expensive and difficult to manufacture than competing designs, they do not saturate or heat up beyond the Curie point, thereby becoming irreversibly damaged and destroying the RF transistors in the process.

Basic Quad K-Type Analog Thermocouple Amplifier
SEN-30103-K1
-
Analog thermocouple amplifier board based on the AD849x from Analog Devices (successor of the AD597). This quad-channel thermocouple board converts the very low voltage signal from a thermocouple to a highly-linear, 0.005V/C output with either 0V or 1.245V offset (both configurations stocked) while removing unwanted noise from the signal. Many supply and output configurations are available with this board, though the PCB was designed with Arduino in mind. Specifically, the output header will plug directly into a standard Arduino Uno or Mega, with a pin-for-pin match for power supply, ground and analog outputs. With a 5V Arduino, temperatures from 0C to 1,000C are possible with the 0V offset board and -249C to 750C with the 1.245V offset board. If using a 3.3V microcontroller (Due, etc), the board must be supplied with no more than 3.3V to avoid damaging the microcontroller. Temperature measurement range is dependent on the supply voltage. It is possible to supply the board with higher voltages to allow temperature measurement over the entire operating range of the K-Type and J-Type thermocouples, allowing use with more capable data acquisition equipment.
