Introduction
1.1 About Production Test USB DAQ Type 3670
Type 3670 is a data acquisition system, specifically designed to be used with CCLD
*
measurement
transducers, that digitizes and streams data through a USB interface to computers running either
macOS
®
or Windows
®
operating systems.
Uses:
•
Real-time, multichannel sound and vibration data acquisition
• CCLD power supply for transducers
• Audio and vibration quality control (QC) of components or sub-assemblies
• Final assembly, test and pack (FATP) stations for finished products
Type 3670 is available in two variants:
•
Type 3670-A-082 – 8 input channels, 2 output channel
• Type 3670-A-088 – 8 input channels, 8 output channels
This user manual covers both variants.
1.1.1 Features
The design of Type 3670 provides exceptional accuracy and fidelity for all acquired or generated
signals. The 110 dB dynamic range allows resolution of signals that differ in amplitude by a ratio of
one million to one.
Design features:
•
Instrumentation-grade acquisition system
• Analogue input and output channels
• 24-bit analogue-to-digital converter (ADC) and digital-to-analogue converter (DAC)
• 150 mW output channels
• Streaming via Core Audio for macOS or audio stream input/output (ASIO
®
) for Windows
• Wide frequency bandwidth
• Single input voltage range covering full dynamic range
• Information-only front panel; no controls on rear panel
• Internal CCLD switch (on/off) on each input channel
• Rugged and light
• IP 50 – dust protected
• Silent operation (convective cooling)
* Constant current line drive, also known as DeltaTron
®
(ICP
®
and IEPE compatible).
