SonixDAQ Software V6.X

SonixDAQ software has new interface with the new SDK 6.x.

Main Window
The SonixDAQ software is separated from the Exam software. This section will only focus on the DAQ software which is used to:
 * Initialize the DAQ.
 * Adjust the DAQ parameters from Side Menu.
 * Selecting the buffer size.
 * Adjusting the gain and TGC curve.

The following figure shows the main user interface of the SonixDAQ software:



Note: If you program the DAQ with one bitstream e.g. 40MHz and want to switch to the other bitstream i.e. 80MHz you need to turn off the DAQ and turn it back on. If you skip this step, the DAQ will always respond as already being initialized and will not load the new bitstream.

Sequence Control
After pressing the "initialized" button, the DAQ software will program the DAQ hardware. Once the DAQ is programmed, the right side menu allows the user to adjust the parameters for data acquisition, start/stop the sequencing, and download/transfer the captured data to PC.



Note: If you program the DAQ with one bitstream e.g. 40MHz and want to switch to the other bitstream i.e. 80MHz you need to stop the DAQ and re-initialized it with the new sample rate. If you skip this step, the DAQ will always respond as already being initialized and will not load the new bitstream.



The flowchart of the supported sequence control is depicted in a figure below and will be explained in detail in the following sections.



Adjust the TGC Curve
The user can obtain the desired TGC curve in the top section of the window. Both adjustable TGC (as a function of depth) and fixed TGC can be programmed.



Imaging Parameters
This window allows the user to adjust the imaging parameters such as The effects of these parameters on data acquisition are depicted in a figure below. Further explanations are provided in the next subsections.
 * Number of Samples: number of samples that will be acquired regardless of the sampling frequency,
 * Receive Delay: the delay (in micro seconds) after the sync signal and before start of data collection,
 * Line Duration: duration of each acquisition in micro seconds,
 * Gain Delay, delay after the transmit before the TGC is applied in micro seconds,
 * Gain Offset, shifts the TGC curve up based on the Gain offset value, the value is in micro volts and it ranges from 0 to 1600 (1.6 Volt maximum gain),
