ACQUISITIONLOGIC AL81G High-Performance Data Acquisition Module

ACQUISITIONLOGIC AL81G

The ACQUISITIONLOGIC AL81G is a high-performance data acquisition module or single-channel analog-to-digital converter (ADC) board, primarily used to convert analog signals into digital signals for processing and analysis by computers or other digital systems. It is suitable for industrial automation, scientific research experiments, medical equipment, and other fields. The detailed introduction is as follows:

• High-Resolution Acquisition: The 8-bit ADC provides high-resolution data acquisition, enabling precise collection of analog signals.

• Fast Sampling Rate: The maximum sampling rate can reach 1GS/s, supporting broadband signal acquisition. The effective sampling rate ranges from 1GS/s to 250KS/s.

• Large Memory Capacity: The onboard memory ranges from 256M samples to 1G samples, supporting long-term data acquisition. Memory operations allow continuous acquisition while transferring data to the PC.

• Diversified Trigger Modes: Supports triggering via software, BNC, four-quadrant encoder input, or internal TTL connection. It also supports pre-trigger and post-trigger functions to capture data before and after trigger events, with a re-trigger time of only 1μs, enabling high-repetition-rate signal acquisition.

• Rich Interfaces: Equipped with BNC interfaces for connecting to various signal sources and supports the PCI Express x1 bus for convenient integration with other devices.

• Number of Channels: 1 channel.

• Resolution: 8 bits.

• Bus: PCI Express x1.

• Power Supply: +12V, +5V, -12V.

• Dimensions: 220mm × 167.6mm × 21.9mm.

• Weight: 500g.

• Operating Temperature: 0°C to 50°C.

• Storage Temperature: -40°C to 85°C.

• Humidity: 5% to 95% (non-condensing).

• Abnormal Data Acquisition: If the collected data is inaccurate or missing, it may be due to the input signal exceeding the range or input impedance mismatch. Check whether the input signal is within the rated range and confirm that the input impedance settings are correct. If an ADC chip failure is suspected, try restarting the module. If the issue persists, contact the manufacturer to replace the chip.

• Trigger Failure: If data is not acquired as expected after setting the trigger, the trigger mode may be incorrectly configured. Verify that the trigger mode settings match actual requirements and reconfigure the correct trigger mode. Alternatively, check if the trigger signal source is working properly and if the connection is secure.

• Communication Failure: If the module cannot communicate with a computer or other control systems, it may be due to a bus connection issue. Check for loose PCI Express x1 bus connections and ensure they are secure. Incorrect communication parameter settings may also be the cause; confirm that parameters such as baud rate, data bits, and stop bits match the host computer settings.
