Sundance SMT1026 - Manual (Page 46)

Test: Check this check box to use the ADC test data as input data. In the next step, the
data will be saved in two separate files. One file should contain a ramp with a positive
slope. The other file should contain a ramp with a negative slope.
Channel I only ADC input: Check this check box to use the connector of channel I as the
only input source for channel I and Q.
Configure ADC: Press this button to configure the ADCs of the SMT391.
3 - Acquisition:
File to save data: Set the file to which the data should be written.
Bytes to acquire: Set the size of the acquisition in bytes (or 8-bit samples).
Bytes to avoid: Set the number of bytes (or 8-bit samples) to avoid before starting the
acquisition. This can be useful in some cases. For example, the host comport on the
SMT310Q has a very small buffer that can overflow before the acquisition starts. By
setting the "Bytes to avoid" field, the comport buffer gets empty before starting the
acquisition.
Host link: Select the link used between the host and the carrier board. Most of the time it
will be the host comport but sometime it's possible to use the host RSL.
Acquire data: Press this button to start an data acquisition.
5 Examples
The SMT1026 provides several examples to illustrate the used of the Sundance's FPGA
library.
There is an example for each supported FPGA module and a more generic one.
Those examples are organised in three folders:
•
Firmware
•
Host
•
Output
5.1 Firmware
This folder contains several firmware for the FPGA-only module.
It's installed in the following directory: " C:/Program
Files/Sundance/SMT6026/Examples/SMT391/Firmware ".
