This is the DAQ-9600G Mainframe (with GPIB).
The DAQ-9600 data acquisition system is a modularized data acquisition system with high flexibility and higher performance. The mainframe is equipped with 3 module slots and a built-in precision 6 1/2 digital DMM is the core of its test and measurement. 5 modules are available to meet different measurement needs. For the research and development of analyzing product characteristics or the production and manufacturing of system testing or fault diagnosis, a data acquisition system with flexibility and high performance can effectively fulfill different measurement requirements by expansion and change that make the overall test simpler, faster and more reliable.
 
The DAQ-9600 provides 3 module slots, and all of which can be used to install and control selected modules. 5 different modules are available to meet different measurement needs. These modules include general-purpose modules, multi-function modules, matrix module and high-voltage and high-current module. Users can choose, mix and match these modules to obtain the functions as required. The measurement channels of each module can be configured independently, including measurement function, range, speed and the advanced measurement functions such as offset compensation. The DAQ-9600 can provide up to 60 two-wire measurements, 120 single-ended measurements, or 96 matrix crosspoints in a half-rack, which saves work space and cost when completing complex and diverse measurement tasks.

The test and measurement core of the DAQ-9600 is a 6 1/2-digit DMM, which has the functions and performance of an industrial-grade DMM. It can measure and convert 14 different input signals. In addition to high resolution, it also provides basic accuracy of 0.0035% DC voltage, 0.05% basic accuracy of AC voltage and 0.01% basic accuracy of resistance (within one-year calibration period). The functions of this DMM can be used with general-purpose modules (DAQ-900/ DAQ-901), multi-function module (DAQ-903) and high-voltage and high-current module (DAQ-909). All multiplexer modules use "disconnect before connect" scanning to ensure that only one channel (or a pair of channels) is closed at a time.
 
The DAQ -9600 does not rely on external or plug-in signal conditioning modules to handle functions other than DC voltage, which not only greatly reduces noise and errors generated by external wiring from entering the system, and improves reliability. At the same time, it does not have unnecessary cables, wire distribution boxes and signal conditioning components that makes configuration quicker and easier. Taking temperature measurement as an example, the measurement of thermocouples is often accompanied by the Seebeck effect (the thermoelectric phenomenon in which the temperature difference between two different electrical conductors or semiconductors causes a voltage difference between two substances). All DAQ-9600 modules provide cold junction compensation (except DAQ-904) to ensure maximum accuracy for all channels measuring thermocouples, avoiding the use of temperature extension wires with external cold junctions, which will increase noise and errors generated by external wiring into the system.
 
The DAQ-9600 can store the measurement results without connecting to a PC with the non-volatile memory capacity of 100k readings. Users can store the measurement results inside the system first, and then connect to a PC to collect data. In addition, for larger memory capacity, the DAQ-9600 also supports the USB storage function, which can directly record data to an external USB flash drive, or copy the data of the internal non-volatile memory to the flash drive for follow-up analysis.
