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.
