RF Evaluation and Development Kits, Boards are essential tools for electronic engineers and scientists when developing a new electronic device, especially wireless networks and devices.DC795A is one of them. It is an 8-channel RF signal generator that is designed for wireless applications in development, evaluation, and production. This article will focus on the DC795A application field and working principle.

The DC795A operates in the frequency range from 450 MHz to 6.0 GHz, and offers an output level of up to +20 dBm (100 mW). It supports a variety of popular modulation formats such as AM, FM, PM, BPSK, QPSK, and Continuous Wave (CW). The DC795A also has a wide range of features, including independent channel programming, integrated antennas, and automatic frequency control.

DC795A’s extensive application field are wireless communication, radar, navigation, RF remote control, radio broadcasting, localization, etc. For example, the DC795A is perfect for testing wireless cameras, RFID readers, RF remote control systems, and other general purpose radios. Additionally, it can be used to evaluate RF receivers, antennas, and propagation characteristics of wireless networks.

The DC795A features an intuitive user interface that allows for quick programming and control of the device. The user can easily adjust the RF output parameters such as the frequency, power, and modulation format. The DC795A also has a flexible command format that can be used to control the device, as well as the ability to connect to external computers through a USB interface or Ethernet.

The DC795A is powered by a 12-volt, DC power source that is compatible with most laboratory power supplies. The DC795A is also equipped with an integrated fanless liquid-cooled design that prevents overheating and maximizes performance. The DC795A can also be operated in standalone mode, where all parameters can be set through the user interface.

The DC795A’s working principle is based on direct digital synthesis technology, which allows signals with very low distortion and high accuracy. The DC795A consists of a phase-locked loop (PLL) that synthesizes a digital signal from a reference oscillator, amplifies the signal, and then sends it to the output stage. The output stage includes a MOSFET amplifier that delivers a precise and adjustable output. The mixed-signal circuitry controls the power, frequency, and other parameters of the signal.

Overall, the DC795A is an ideal choice for designers, developers, and engineers who need an advanced RF signal generator for their wireless development projects. With its wide range of features, intuitive user interface, and direct digital synthesis technology, the DC795A is sure to provide reliable and accurate results.
