Analog Input of USB-6008/6009 Reads 1.4V in RSE Mode when No Signal is Connected
Hardware: Multifunction DAQ (MIO)>>Portable>>USB-6008, Multifunction DAQ (MIO)>>Portable>>USB-6009
My USB-6008 or USB-6009 is reading around 1.4V in referenced single-ended (RSE) mode when no signal is connected. Is this expected?
Yes, when there is no signal connected to the analog input of the USB-6008 or USB-6009, a reading of around 1.4V in RSE mode is expected. This is due to the internal resistor network.
