QiwenSheng Posted October 5, 2023 Share Posted October 5, 2023 Hello, I am trying to get more details for the USB-1208FS-Plus: 50 kS/s sample rate, 12-bit resolution. In my project, I need to transfer the digital signal to the analog signal. For the two analog output channels, is the analog output from the DAC? I would also like to use python to control the DAQ. Does the DAQ support the remote control with python? Thanks a lot. Link to comment Share on other sites More sharing options...
0 Fausto Posted October 5, 2023 Share Posted October 5, 2023 Hello @QiwenSheng. The USB-1208FS-Plus is supported by MCC's Universal Library Python API for Windows (mcculw). Please reference the MCC Universal Library Help file for supported functions. https://files.digilent.com/manuals/Mcculw_WebHelp/ULStart.htm The USB-1208FS-Plus has two analog output channels. Each analog output channel can be paced at rates up to 50,000 updates per second. The output range is 0 V to 5 V. User's guide: https://files.digilent.com/manuals/USB-1208FS-Plus.pdf After installing the MCCDAQ software, https://digilent.com/reference/software/mccdaq-cd/start, Python for Windows examples can be found in the local path: 'C:\Users\Public\Documents\Measurement Computing\DAQ\Python' Regards, Fausto Link to comment Share on other sites More sharing options...
0 QiwenSheng Posted October 5, 2023 Author Share Posted October 5, 2023 Hello Fausto, Thanks for your quick response and information. I would like to input the digital signal to the DAQ first, and then obtain the analog signal from the analog output channel. The DAQ functions as a digital-to-analog converter. Could it work for the USB-1208FS-Plus? Thanks a lot. Qiwen Link to comment Share on other sites More sharing options...
0 Fausto Posted October 5, 2023 Share Posted October 5, 2023 The device supports analog input and digital input channels to capture your signal(s). Once stored to memory, a user can process the data and then fill an output buffer for the analog output channel(s). Link to comment Share on other sites More sharing options...

0 QiwenSheng Posted December 29, 2023 Author Share Posted December 29, 2023 I am reading the Vout01.py Python sample. Does the USB-1208FS-Plus have the D/A converter? Thanks. Qiwen Sheng Link to comment Share on other sites More sharing options...
0 Fausto Posted December 29, 2023 Share Posted December 29, 2023 Hello @QiwenSheng. The USB-1208FS-Plus does have a D/A converter with a 0 - 5 V output range. Please reference MCC's Universal Library Help for supported functions. Regards, Fausto Link to comment Share on other sites More sharing options...
0 QiwenSheng Posted January 2 Author Share Posted January 2 Hi Fausto, Thanks for your information. When I was running my code on Windows 11, a UL error occurred. Code: 126 Message: Cannot find CB.CFG file. I also checked the 'C:\Program Files (x86)\Measurement Computing\DAQ'. I didn't find the CB.CFG file. Is there any method to generate the CB.CFG file? Thanks a lot. Qiwen Sheng Link to comment Share on other sites More sharing options...
0 Fausto Posted January 2 Share Posted January 2 Hello @QiwenSheng. MCC's cb.cfg file resides in the C:\ProgramData\Measurement Computing\DAQ directory. InstaCal creates the cb.cfg file with a list of MCC devices connected to the target system. Regards, Fausto Link to comment Share on other sites More sharing options...
0 QiwenSheng Posted January 2 Author Share Posted January 2 Hi Fausto, I still cannot find the "cb.cfg" file, even reinstalling the InstaCal. Are there other ways to generate "cb.cfg" file? Thanks a lot. Link to comment Share on other sites More sharing options...
