This user's guide describes the characteristics, operation, and use of the Precision Signal Injector
evaluation module (PSIEVM). The EVM facilitates the evaluation of single-ended, differential, and high-
voltage SAR analog-to-digital converters (ADC) by generating a very low distortion, low-noise signal. This
signal generator is powered by and controlled by the USB port. This user's guide provides a description of
how to configure and control the hardware using the provided software GUI.

Overview The Precision Signal Injector Evaluation Module (PSIEVM, or PSI for short) is a platform for testing and evaluating the performance of successive approximation register (SAR) ADCs. The board is strictly designed to provide a low distortion, low-noise, 2-kHz input signal for driving the input of the ADC and pairs with most of TI’s SAR ADC evaluation modules (EVMs).

  • Page 21: Signal Path Illustration

    Connectors for Signal Output The PSIEVM is designed to be easily interfaced with a TI SAR ADC EVM via a subminiature version A (SMA) connector. P2, P4, and P5 are SMA connectors that allow analog output connectivity through coaxial cables.

  • Page 22: Optional Features

    Ensure the connected power supply is at a maximum of 15 V. Fluctuating above 15 V could result in component damage. The PSIEVM must still be connected to the computer via the USB cable but this is only used for data from the GUI and not power.

  • Page 23: Other Considerations

    Note that by adding output resistance, there will be a voltage divider from the output resistance of the PSI and the input resistance of the DUT. The PSIEVM is fully calibrated with R53, R59, and R100 as 0-Ω resistors. Cable Selection It is best practice to minimize the length of the cabling used between the PSI and the DUT.
