USB-1608G problems

[georgiev1992]

Hi guys,

I have a USB-1608G in the lab and I am trying to change the mode from differential to single mode(SE) and change the input voltage range per channel but in the DAQami GUI I see the channel mode grayed out and it says differential. When I go to the "Channels" tab the only option for the range is +-10V. I tried to connect through the python library "UL" by using the ul.get_daq_device_inverotry(InterfaceType.USB) but it returns empty. FYI the DAQ is connected through USB and I can talk to it through the DAQami GUI.

Hello,

The USB-1608G input channel mode can be set using ul.a_input_mode(board_num, AnalogInputMode.SINGLE_ENDED). Check out the attached Python script that demonstrates device discovery, setting the input mode, and collecting data from four channels.

Best regards,
John

Thank you for the quick response. My main issue is that: No devices are detected, when I run the example script. My instrument is connected through USB that was provided in the box.

I forgot to mention that the input mode setting in DAQami is on the USB-1608G (Device 0) tab.

I got the instrument running and I ran a 1000 measurements on a known signal and the variation was -/+ 2.5mV. We were told that the precision is better than 1 mV. Is there anything we need to do to calibrate the instrument?
