 ===== Introduction ===== ===== Introduction =====
 The EV-HT-200CDAQ1 reference design kit includes a high temperature circuit assembly with data acquisition front-end and microcontroller, optimized firmware, data capture and analysis software, source code, design files, bill of materials, test reports, and breakout boards.   This platform is suitable for reference design, rapid prototyping  and lab testing of high temperature instrumentation systems.   The dimensions and construction of the circuit assembly have been designed to be compatible with oil and gas instrumentation form factors, although it can also be used as the basis for other high temperature applications.    A block diagram of the main board is shown below.  For a detailed overview of the platform features, see the [[resources:eval:user-guides:high-temp:ev-ht-200cdaq1:overview|overview]] wiki page.   The EV-HT-200CDAQ1 reference design kit includes a high temperature circuit assembly with data acquisition front-end and microcontroller, optimized firmware, data capture and analysis software, source code, design files, bill of materials, test reports, and breakout boards.   This platform is suitable for reference design, rapid prototyping  and lab testing of high temperature instrumentation systems.   The dimensions and construction of the circuit assembly have been designed to be compatible with oil and gas instrumentation form factors, although it can also be used as the basis for other high temperature applications.    A block diagram of the main board is shown below.  For a detailed overview of the platform features, see the [[resources:eval:user-guides:high-temp:ev-ht-200cdaq1:overview|overview]] wiki page.

 In **Burst Mode**, the firmware allows for a high sample rate (minimum = 2.4 microseconds) capture for short intervals.  Specific channels and rates are manually set.  In **Continuous Mode**, all channels are sampled sequentially at a fixed sample period of approximately 10 microseconds, as shown in below diagram.  A full sequence is conducted at a periodic rate set by the user. In both modes, data is transmitted over the UART interface to the HT DAQ Viewer for both display and analysis.    In **Burst Mode**, the firmware allows for a high sample rate (minimum = 2.4 microseconds) capture for short intervals.  Specific channels and rates are manually set.  In **Continuous Mode**, all channels are sampled sequentially at a fixed sample period of approximately 10 microseconds, as shown in below diagram.  A full sequence is conducted at a periodic rate set by the user.
