This guide provides practical tips and techniques to maximize the performance of your DAQ-9600, ensuring that you can capture and process data swiftly and accurately.
Feature of each module
Each module has its own features and functions. Understanding the module is the first important step.
| Module | Construction | Type | Speed （ch/sec） |
Max volts | Max amps | Bandwidth | Thermal offset | Comments |
| DAQ-900 | 20 CH Multiplexer | 2-wire solid-state （4-wire selectable） |
450 | 120V | 10MHz | <4 µV | Built-in cold junction reference | |
| DAQ-901 | 20 CH Multiplexer＋2 CH Current | 2-wire armature （4-wire selectable） |
80 | 300V | 1A | 10MHz | <4 µV | Built-in cold junction reference 2 additional current channels（22 total） |
| DAQ-903 | 40 CH Single-Ended Mux | 1-wire armature （common low） |
80 | 300V | 10MHz | <1 µV | No four-wire measurements | |
| DAQ-904 | 4 × 8 Matrix | 2-wire armature | 300V | 1A | 10MHz | <1 µV | ||
| DAQ-909 | 8 CH HV Multiplexer＋2 CH Current | 2-wire armature （4-wire selectable） |
60 | DC 600V AC 400V |
2A | 10MHz | <4 µV | 2 additional current channels（10 total） |
DAQ-900 module is a solid-state relay module that provides two groups (A/B) of 10 2-wire channels each and features the top scan speed (450 channel/second) that satisfy the high-speed demand user.
DAQ-901 module is a comprehensive multiplexer for general scanning. The same module can mix 2-wire and 4-wire channels; at the same time, the additional 2 current input channels can be used for AC and DC current measurement without external shunt resistors.
DAQ-903 module can switch 40 single-wire inputs per module. It can be used for common-low applications such as battery testing, component characterization and desktop testing.
DAQ-904 module can provide the most flexible connection path between your DUT and the test system, allowing different test instruments to be connected to multiple points on the DUT at the same time.
DAQ-909 module is a multiplexer specially designed for high voltage, providing 8 channels for DC 600V / AC 400Vrms voltage, and 2 channels for 2A current measurement.
Fixed-Range vs Auto-Range
Although Auto-Range is often used to ensure the correct range and provide convenience, if the value of the DUT is fixed within a certain range, we highly recommend choosing a specific range instead of Auto to save time.
Range Low
When measuring current, its value may vary across multiple ranges, making it impractical to choose only one specific range to save time. However, using the Auto-Range setting decreases measuring efficiency, creating a dilemma for the operator. In this scenario, the convenient Range-Low function can be used to find a balance between the two.
For example, if we already know the current range is within 10mA to 2A, then we can choose the Auto-Range with Range-Low (set to 10mA). In the figure below, we can see the detecting range is narrowed, enhancing the efficiency dramatically compared to the Auto-Range only mode.
Speed vs Resolution
Speed setting is also an important factor in overall efficiency. Reading speed and resolution are two factors that counterbalance each other: higher speed sacrifices resolution and signal-to-noise ratio, while lower speed provides better resolution.
Conclusion
There is no single best setting that can handle all scenarios. Only by understanding the user's needs and the features of the device and modules can we find the most appropriate setup to optimize the measurement.
As mentioned previously, the first step is to identify the user's needs to choose the correct module (speed, resolution, current measurement, high voltage measurement, channel numbers, etc.). Then, set the parameters based on these requirements to maximize performance.
In conclusion, a tailored approach that considers both the user's specific needs and the device's capabilities is essential for achieving optimal measurement efficiency and accuracy.
