Ok, it works doing like this ! Before, I tried to edit directly the time string, but it was not working properly, but clicking on the right digit and then use the arrow to change its value works fine. Thank you!

Hi, I'm using the DAQami software to export a fraction of a TDMS log file. I'm trying to export around 10s of my file, my CSV start with the right offset but the export keeps going until it reaches the last data or max export length instead of the max range. In the same way when I'm opening a TDMS file with DAQami, I can't load less than the max length possible.

Hello, Currently I don't have symetrical power available yet, I only have 0-24V and 0-5V. Do you have a recommendation ? Or should I add one, and use TL081 op amp for example ?

Hi Qiwen, You were thinking to use an operational amplifier as a Voltage follower ? I was looking for a pre-made solution but signal conditionner are expansive and i need 10 of them, so i was thinking to implement a simple voltage follower, but I'm not sure if it's the right choice. Clément

Hello Fausto, Thank you for your fast answer ! I didn't know the TDMS file, I thought it was logging only into the CSV. Regards, Clement

Hi, I need to log data from a USB-1608G DAQ. The DAQami interface is very easy to use, but is only capable to log 1.000.000 lines. I need to be able to log much longer files, like a few minutes at 10KHz. The Labview option is to slow to log at this rate, and create a python implementation as reliable as DAQami will be time consuming. Is it possible to log more data with DAQami ? Regards, Clement

Hi, I have a probleme similar to this one, but I'm using a USB-1608G. After verification our sensors have an impedance between 1 and 2 kOhms. Do you have any recommandations on how to implement the convertion from high impedance signal to low impedance ? Regards, Clement

Do there is an other way than time stamping each data on reception manually, witch is greatly reducing the max acquisition speed ?

I'm not sure why, but probably due to some incompatibility with the release of mcculw I'm using (mcculw 1.0.0), but your example doesn't seem to work. So I try a similar technique by editing the "a_in.py" do to something similar, and it capped at around 1k/s for only one channel. It should go at max 250ks/s/channel.

Hi, We recently bought an USB-1608G to improve our test bench logging capacity. We want to log analog data at, at least 1000Hz for a long period of time, higher than the 1.000.000 lines possible with DAQami so we turn ourself over the mcculw for Python. The example "a_in_scan_file.py" works fine, but we also want to add a timestamp which is not provided in any example. Is there a way to efficiently and accurately add one ?
