RF evaluation and development kits, boards provide designers with the necessary components for developing and testing RF (Radio Frequency) circuits. DC715A from Teledyne LeCroy is one of the commonly used RF development and evaluation boards. It is a digital RF generator with frequency range from 140kHz to 3.5GHz.

DC715A has a wide application field mainly include general purposes, communication, education, laboratory automation, electronics, defence, automotive, medical, radar, aerospace industry, etc. It has been widely used in signal source test, loop and sense test, etc.

DC715A offers several advantages for both users and developers. It has high output power with power level adjustable from 0 dBm to 24 dBm. It also has low noise floor with wide dynamic range (better than 100 dBs). In addition, it has low harmonic and spurious levels and covers several different standard modulation formats such as Frequency Shift Keying (FSK), Phase Shift Keying (PSK), Amplitude Shift Keying (ASK), Quadrature Amplitude Modulation (QAM), performance detection, etc.

Moreover, DC 715A has a friendly, intuitive and easy-to-use graphical user interface (GUI) which is designed for Windows XP and Windows 7 operating systems. Furthermore, it has front panel display for controlling the operations depending on user’s settings.

In terms of its working principle, DC 715A works in the following steps. Firstly, the signal to be generated is entered into the signal source. Secondly, the signal is amplified by the amplifier and is tailored to the desired bandwidth. Thirdly, the signal is passed through an attenuator and leveled-off before being sent to the digital-to-analog converter. Finally, the signal is sent to the RF generator output port and is up-converted with a local oscillator reference signal for the desired center frequency.

Therefore, DC715A is an excellent RF development and evaluation board that can be used in a wide range of applications due to its features. It offers low noise floor, low harmonic and spurious levels, wide dynamic range, and several different modulation formats. Furthermore, it has a highly intuitive GUI, and a front panel for controlling different operations. As it is easy-to-operate, even the people with less technical experience can use it efficiently.
