    We just received our USB-SA124B. My colleague successfully installed, and ran spike on his 10+ year old Dell laptop. I, however, installed spike version 3.1.8, and the drivers (CDM v2.12.00 WHQL Certified.exe) on my one year old, Windows 7 laptop I can’t seem to get the spectrum to display on the screen. When I plug in the unit to the USB I get a solid green light, but when I start the program the software doesn’t display the actual spectrum, it just displays whatever was on the desktop behind it. I suspect that the GPU and the analyzer aren’t syncing properly, but I’m not sure how to remedy this.

    Hi Troy,

    Yes, this is very likely related to the GPU. We utilize OpenGL to raster several of the displays and require at minimum OpenGL 2.0 support. Support for OpenGL 2.0 in hardware has been around for ~8 years so for a 1 year old laptop to have trouble with this is odd.

    The first thing I would try is updating drivers. Look on your manufacturers website for any potential graphics/display drivers. You can also try updating them directly through the display manager. You can also update drivers through ‘Windows Update’ (keep updating until it can’t find any more updates).

    If this does not resolve your issue, let me know what PC you are using (make/model/CPUmodel) and I can help you find drivers direct from the parts manufacturers. You can reply here or to my email at aj@signalhound.com

    Regards,
    Andrew
