AD9125 Evaluation Board
The AD9125 the evaluation board has clocking and analog quadrature modulator circuits to ease system level solutions. The AD9125 evaluation board comes in two models:
- AD9125-M5372-EBZ: has the ADL5372 modulator on-board.
- AD9125-M5375-EBZ: has the ADL5375 modulator on-board.
To operate the evaluation board, apply power, a clock source, a digital data source, and observe the DAC output on either a spectrum analyzer or an oscilloscope. A low jitter sine or square wave clock works well as a source. The evaluation board comes with software to program the SPI port. Via the SPI port, the DUT and clock circuitry can be programmed into any of its various operating modes.
Documentation and software updates for using High-Speed DAC Evaluation Boards are included in individual, self-extracting update files.

Data Pattern Generator
The Data Pattern Generator (DPG) is a bench-top instrument for driving vectors into high-speed digital-to-analog converters. The DPG connects to a USB on a PC and allows a user to download a vector from the PC into the internal memory of the DPG. Once downloaded, the vector can be played out to an attached evaluation board for a specific DAC at full speed. This allows for rapid evaluation of the DAC with both generic and custom-generated test data.
