Thank you @attila, Just to confirm, if I use oversampling, the resolution is 16 bits. Then, the ADC resolution for the 50V range is around 0.7mV?

Thank you @attila, The voltage range that I am looking to sense is ~4V. If I understand correctly, I should scale the signal down by 10 times using 0.1X attenuation and a range less than or equal to 200mV so that I can keep the resolution at 130uV, correct?

Hello, The resolution for the ADP345 is 14-bit with +/-25V (50V difference) input range. Is it possible to adjust the input voltage range (reduce it) to achieve better voltage sensing resolution? Thanks,

Thank you, JColvin, for your answer. By using the record mode, I cannot see the acquired values on the screen until the recording is done, correct? Is it possible to see the values as they change while using record mode? Mohammad

Hello, I am using the ADP3450. I am wondering if there is any way I can start sampling at time=0sec or time=0min. I tried to manipulate the parameters in the "Time" window, but I could not achieve what I was looking for. As shown in the attached photo, the sampling did not start at time=0. Also, when I try to export the raw data, for Ch#1, for example, it shows that the first data point is recorded at t=-147sec as shown in the second attached photo. Could you please help? Thanks, Mohammad

Ok, John.

Hello John, Thank you for your comment. I actually tried to use the power supply of the working to power the second one, however, the "device ready" LED is still off. Once I connect the USB2020 I hear the sound as if a new device is connected to the PC. However, I do not have access to the device. Serial number for the first USB-2020 (good board): HE1793938 Serial number for the second USB-2020 (not working): HE1631214 Regards, Mohammad

Hello, I am using USB2020. I have two devices. The first one was detected directly by the host PC and the "device ready" blue LED is ON. However, LED in the second one is OFF all the time. I made sure that the 9V input is present at the board input supply terminals. Also, I unplugged and plugged back the USB cable to the host PC. As shown in the attached photo, the device is present in the PC's devices list. However, I have no access to it. Also, I tried to see if Matlab toolbox can detect but I did not. Could you please help with that? Appreciated, Mohammad

Hey Arthur, Thank you for your valuable comment. I already have the training data set to train my neural network on. Once I train the neural network, I believe I can save it such that I use it every time I run the script (So I do not have to train it every time). Do you think that is correct? Coming to the performance part, could you please explain more? Do you mean the rate of the process when running the python script locally is slower than that of an average PC? I would appreciate it if you can provide me with more insights on the performance when running the python script with AI locally vs a PC. Thanks again, Mohammad

Hello, I am planning to write my own python script using the SDK tool in Waveforms while using ADP3540/ADP3520. Can I run a neural network in the python script? If yes, can the neural network be trained using an external data set? I plan on the following: 1) Training the neural network on a dataset that is already available. 2) Make the ADP device sample data (For example, a voltage value). 3) The sampled data is fed into the pre-trained neural network in real time. 4) The neural network gives an output based on the supplied sampled. 5) Sample data again. 6) A new output from the neural network. 7) repeat steps 2 to 6, and so on. Is what I described possible? what could be the limitations? I would highly appreciate your valuable answers and clarifications. Thank you so much. Mohammad

Hello John, Could you please help me with the above issue? Thanks a lot. Mohammad

Hello Joh, Thank you for your reply. Then, I might try to use Labview to have Burst mode sampling and then acquire the samples in Matlab from Labview. Do you think this is a valid option? Thank you! Mohammad

Hello John, Thank you for your reply. It seems that you answered my questions based on the USB-202 not based on the US-B2020. Could you please help me addressing my questions based on the USB-2020? Thank you for your time. Mohammad

Hello, I am writing with some questions about using Matlab to log data from MCC-USB 2020. I would appreciate your help. 1. Is it possible to use BURST mode in Matlab? If yes, is there any guide/documentation related to this? 2. Is it possible to change the input voltage range in Matlab? I assume that Matlab considers the +-10V range but would like to decrease this range if possible. Thank you for your time and consideration. Best, Mohammad
