Appendix 2. ADV Real-Time Binary Data File Format
This appendix describes the format of the binary files generated by the ADV data acquisition
software. The format is the same for all ADV configurations.
A2.1. Overview of Binary File Format
There are four basic data types in the ADV real-time binary files: file configuration, data sample,
event counter, and analog input sample.
• File Configuration Structure (578 bytes)
• Data Sample 1 (18-30 bytes)
• Event Counter 1 (2 bytes)
• Data Sample 2 (18-30 bytes)
• Event Counter 2 (2 bytes)
• ! ! ! ! !
• Data Sample N (18-30 bytes)
• Event Counter N (2 bytes)
A2.1.1 File Configuration Structure
ADV system configuration data is recorded once at the beginning of each binary data file. The
file configuration structure is split into two areas: user setup parameters (324 bytes) and probe
configuration parameters (254 bytes). The User Setup and Probe Configuration structure defini-
tions are given below in the C language code used to access the data files.
