Hardware Specs

U6-Pro vs. U6
The U6-Pro has all the features of the normal U6 with the addition of an auxiliary low-speed high-resolution (24-bit) sigma-delta ADC. Under software control you specify a resolution setting that determines whether the high-speed converter or high-resolution converter is used for any given reading. The high-resolution converter is only an option in command/response mode, and is not used in stream mode.
Analog input resolution from the high-speed converter (U6 and U6-Pro) varies from 16.1 bits (RMS or Effective, resolution index = 1) at max speed (<1 ms conversion time), to 19 bits (resolution index = 8) at slower speeds (2 ms conversion time). Analog input resolution from the high-resolution converter (U6-Pro only) varies from 19.7 bits (RMS or Effective, resolution index = 9) at max speed (4 ms conversion time), to 22 bits (resolution index = 12) at slower speeds (160 ms conversion time). For more detail see the Command/Response Data Rates and the Noise and Resolution Tables. The U6-Pro has an obvious benefit at resolution index = 12, but there is also a more subtle benefit when using higher gains (x100 and x1000) as the time at resolution index = 9 is better than most times from the high-speed converter.
One more benefit to the U6-Pro, is that it has very high 50/60 Hz rejection when set to resolution index = 12.
UD Series Software Options
- Sample Applications: All free. LJControlPanel (part of the normal Windows installation) has a test panel where you can view all inputs and manually control all outputs. LJLogUD collects analog input data in command/response mode (generally 100 Hz or slower), displays it on screen, and writes it to file. LJStreamUD collects analog input data in stream mode (generally 10 Hz or faster), displays it on screen, and writes it to file. Both applications are free.
- Programming: All free. If you know any language we probably support it. This includes C, C++, C#, Delphi, Java, LabVIEW, LabWindows/CVI, MATLAB, Python, and Visual Basic (VB6/VB.NET). Start on our UD Series Programming page.
- DAQFactory: Free and paid versions. DAQFactory is measurement and automation software from Azeotech, that allows non-programmers to make custom applications. Start on our DAQFactory page.
