Keyence VE7800 PCB Pics
I couldn’t really resist taking a quick look inside the SEM. The instrument connects to the host PC over USB and firewire. These go to two separate boards inside the instrument. We removed the USB connection during operation and saw that images were still being acquired. It’s reasonable to assume that the firewire connection is used for image acquisition only, and that all control signals go over the USB connection. The USB device ID is 0720:1005.
Below are some quick snaps of the PCBs for reference.
