Attenuators are electrical circuits used to reduce the amplitude of an incoming signal, without substantially distorting its waveform. AT-115-WP1(40) is a particular attenuator designed for specific application fields. This article outlines its key features, its application fields, and its working principles.

Feature overview

The AT-115-WP1(40) is an adjustable constant impedance variable attenuator that can reduce signals of up to 40 dB. It is a rack mountable unit with a sealed, hard anodized aluminum package. The housing has two chambers, one for the electronic components and the other for a temperature controlled fan. The fan is adjustable to maintain operating temperature within a specified range. The unit also features a BNC input connector and a BNC output connector. Its primary power supply is 175 to 260 VAC, and it can also be powered from an external battery pack.

Application fields

The primary application for the AT-115-WP1(40) is in broadcast and communication systems, where its adjustable constant impedance is required to reduce signal levels without degrading the quality of the transmission. It is also used in medical imaging systems, where its adjustable constant impedance is needed to prevent transmission distortion at different signal levels. Lastly, the AT-115 is suitable for use in RFI/EMI applications, where its adjustable constant impedance allows secure transmission with minimal interference.

Working principle

The working principle of the AT-115-WP1(40) is based on the principle of negative feedback. The device is designed with two variable resistors in a bridge network, with the input and output signals connected in series. The input signal is divided between the two variable resistors in a ratio of 40:60. The individual resistances are then connected to a negative feedback loop, with the output voltage proportional to the difference in resistance. This loop then adjusts the individual resistances of the two variable resistors, providing the necessary attenuation. Thus, the attenuator acts as a variable resistor, reducing the amplitude of the incoming signal without distorting its waveform.

Conclusion

The AT-115-WP1(40) is an adjustable constant impedance variable attenuator designed for applications in broadcast, communication, medical imaging, and RFI/EMI systems. Its primary power supply is 175-260 VAC, and it can also be powered from an external battery pack. The device operates by adjusting two variable resistors in a bridge network on a negative feedback loop, reducing the amplitude of an incoming signal without distorting its waveform. This makes it a valuable tool for reducing signal levels in any of the aforementioned industries.
