Issue Details

I am trying to acquire from both channels using the external trigger of the PXIe-5122 board. It acquires one channel fine but when the second channel is activated, it jitters around instead of being synchronized with the trigger and the first channel. When I deactivate the first channel, the second works fine. 

Solution

This is a known issue of the NI-SCOPE 21.0 driver for this device. This can be fixed by upgrading the firmware of the PXIe-5122. To update firmware, run the Firmware Updater application from one of the following locations:
  • Windows XP and Windows 7/Vista 32-bit: C:\Program Files\National Instruments\NI-DAQ\fpgafiles\ni5122\NI PXIe-5122 Firmware Updater.exe.
  • Windows 7 64-bit/Vista 64-bit: Program Files (x86)\National Instruments\NI-DAQ\fpgafiles\ni5122\NI PXIe-5122 Firmware Updater.exe.
    • For Windows 10 it should be in the same location. 
This application will upgrade your firmware to the latest available version that works with this driver. After the application has finished running, you will be required to power down your computer and PXIe chassis to complete the firmware update.
