Description: NI 9775 is a 4-channel 20 MS/S
digitizer with volatile and non-volatile memory.
Volatile Memory
| Type | Size | ADC Configuration | PLL Configuration | Battery Backup | User1 Accessible | System Accessible |
|---|---|---|---|---|---|---|
| SDRAM | 128 Mb | 34 bytes | 24 bits | No | No | Yes |
Non-Volatile Memory (incl. Media Storage)
| Type | Size | Battery Backup | User Accessible | System Accessible |
|---|---|---|---|---|
| FLASH | 8MB | No | No | Yes |
| EEPROM | 1 KB | No | Yes | No |
Product Usage Instructions
- To cycle power, completely remove power from the device and its
components. This includes shutting down the PC and/or chassis
containing the device. Simply rebooting is not sufficient. - No specific sanitization procedure is required for the volatile
memory. - To access the user-accessible areas of the Device Configuration
EEPROM, follow the instructions in KB 4GHLANQE. This will allow you
to change the calibration password and clear user-defined
information. - For non-volatile memory, no battery backup is provided. The
device retains its contents when power is removed. - The non-volatile memory can be accessed by the system without
physically altering the product. - Clearing of data in user-accessible storage locations can be
done using standard read and write commands to the storage
device.
Note: The information provided above is based on the October
2016 version of the user manual. Please refer to the most recent
version at ni.com/manuals for any updates or changes.

Procedures
Procedure 1 Board Assembly Part Number identification: To determine the Board Assembly Part Number and Revision, check the top left corner of the white label on the bottom of the module (19xxxx<REV>-0xL).
Procedure 2 – Device Configuration EEPROM (Calibration Metadata): The user-accessible areas of the Device Configuration EEPROM are exposed through a calibration Applications Programming Interface (API) in LabVIEW. Follow the instructions in KB 4GHLANQE for changing the calibration password and clearing the user-defined information.

Terms and Definitions
Cycle Power: The process of completely removing power from the device and its components and allowing for adequate discharge. This process includes a complete shutdown of the PC and/or chassis containing the device; a reboot is not sufficient for the completion of this process.
Volatile Memory: Requires power to maintain the stored information. When power is removed from this memory, its contents are lost. This type of memory typically contains application specific data such as capture waveforms.
Non-Volatile Memory: Power is not required to maintain the stored information. Device retains its contents when power is removed. This type of memory typically contains information necessary to boot, configure, or calibrate the product or may include device power up states.
User Accessible: The component is read and/or write addressable such that a user can store arbitrary information to the component from the host using a publicly distributed NI tool, such as a Driver API, the System Configuration API, or MAX.
System Accessible: The component is read and/or write addressable from the host without the need to physically alter the product.
Clearing: Per NIST Special Publication 800-88 Revision 1, “clearing” is a logical technique to sanitize data in all User Accessible storage locations for protection against simple non-invasive data recovery techniques using the same interface available to the user; typically applied through the standard read and write commands to the storage device.
Sanitization: Per NIST Special Publication 800-88 Revision 1, “sanitization” is a process to render access to “Target Data” on the media infeasible for a given level of effort. In this document, clearing is the degree of sanitization described.
