Data Acquisition Module, DAQ410

DAQ410 – 2.4 GSPS 9-bit Data Acquisition Module
PRODUCT DESCRIPTION
The DAQ410 modules digitize incoming signals at 2.4 GSPS. The on-board DRAMs
provide up to 512M x 9 bits data memory. The DAQ modules can be controlled by a PC via
a USB interface and a PCIe interface. The clock input is single-ended, 50-Ω terminatedwith a minimum power of 6 dBm. The digitized data can be downloaded, displayed, andanalyzed on a PC. The module accepts a high-speed trigger signal for operations in burstmodes. Two burst modes are offered: single burst and multiple-burst modes. The multipleburst mode allows users to capture multiple folds of signals with trigger events. Optional
hardware average/accumulation enhances dynamic performance under noisy conditions. Themodules come with companion GUI and API.

OPERATION PRINCIPLE
MemoryUSB
AnalogInputs

ADCInterfaceControls

PCIe

DAQ410 is composed of a high-speed ADC, an interface/controls unit, and a memory unit.
The ADC digitizes and multiplexes the captured data to the interface/controls unit. The
captured data is processed and stored in the memory unit according to the operation mode,
data start position and length. The stored data in the memory can be transferred to a PC hostvia PCIe or USB.
The memory unit is capable of 512 M x 9 bits storage. The 512M-point memory is divided
into 65536 equal-length segments. Each segment stores 8192 data points. The captured datafrom the ADC can be stored in user pages, which are defined by the start address and data
length as shown in the following figure. Different captured data can be stored in different
user pages.
Data Length065536Start

The stored data can be uploaded to a PC host for display and FFT analysis.

OPERATION MODE
The module can be operated in three modes: Continuous, Burst and Multiple-burst modes.
In the continuous mode, right after snapshot is clicked, the module starts capturing the input
data until the data length is met. Continuous mode is suitable for capturing repeating
waveforms, where the starting time is not critical.
In the Burst mode, the module starts recording right after the trigger signal is received. The
data is stored in the memory specified by the user pages. Afterward, the module is stopped
and the data can be uploaded for processing. Alternatively, the module can be re-armed torecord the next capture, which can be stored in a different user page.

8EuvisData Acquisition Module, DAQ410

In the multiple-burst mode, the module records several captures with respect to the triggers.
The burst number, the start position, and data length can be specified in the GUI. The total
amount of memory used to store the captures is burst number times data length. This mode
enables users to utilize a compact size of memory to capture widely separated pulsed
signals. The following figure shows three-burst captures with 15 us memory size for threewidely spread pulses over 30 ms.

COMPANION GRAPHICAL USER INTERFACEThe GUI is composed of two sections: the Main controls section and the Data display
section.

In the Main control section, users can define user pages by specifying 1) the starting addressand data length, 2) burst mode and burst count, 3) aliases of the user pages, and 4) file nameto be saved to disk. Users can select a user page and perform acquisition and upload data fordisplaying. The captured data can be saved to a file and processed by other software such asMatlab.
