Double Regulation Power Supply
Double regulation power supplies include: DO series, AxN series, ATR series.The Power Supplies of the AxN series are built with the double regulation technique. The first regulation is obtained by the partialization of the grid circulation angle as automatic variac. The second regulation functions as a linear stabilizer with constant dissipated power. As a result, this solution allows to obtain both low power dissipation and, thanks to the linear regulation, excellent output characteristics.DO series Power Supplies are made with the double regulation technique. A linear stabilization circuit is added to a thyristor-controlled bridge, which allows to reduce the power absorbed by the network. This type of control allows a volume reduction compared to linear power supplies but it preserves the characteristics of low noise and speed of response.ATR linear Power Supplies series are built with the double regulation technique. the first regulation is obtained by the personalization of the grid circulation angle as automatic variac. The second regulation functions as a linear stabilizer with constant dissipated power. As a result, this solutions allows to obtain both low power dissipation and, thanks to the linear regulation, excellent output characteristics.

RF Test Spectrum Measurements over CPRI
Integris 3000
Most modern cell tower network configurations place the Remote Radio Head (RRH) at the top of the tower and the baseband unit(BBU) at the bottom of the tower. While this configuration is advantageous for both computational efficiency and mitigation of RF loss across the cable, it means the only place along RF can be accessed is at the top of the tower. This forces field technicians to have to climb the tower to measure and debug RF noise problems.

Silicon Detectors
Through the photovoltaic effect, detectors provide a means of transforming light energy to an electrical current. The root of the theory behind this phenomenon is a small energy gap between the valence and conduction bands of the detector. When light, with enough energy to excite an electron from the valence to the conduction band, is incident upon the detector, the resulting accumulation of charge leads to a flow of current in an external circuit. Since light is not the only source of energy that can excite an electron, detectors will have some amount of current that is not representative of incident light. For example, fluctuations in thermal energy can easily be mistaken for light intensity changes. A variety of these "non-light" contributions are present and, when summed up, make up the total noise within the detector.
