The GDS2000E design has *no* shielding except for the AFE and the front panel. As a consequence it emits a terrific amount of SMPS EMI. I'll post some photos later. At the moment I can't find my probe.
If you want to see for your self, make up a small loop that slips over a scope probe tip with the grabber removed. Make the loop from tip to ground 1/4-3/8" (6-9 mm). The smaller the loop the better the localization. Its a directional loop antenna. Rotating the loop will indicate the axis and moving along the axis will show you the source
DO NOT USE THE PROBE AS A FORM! MEASURE THE DIAMETERS AND USE DRILL BIT SHANKS TO WIND THE COILS TO SLIP OVER THE TIP AND GROUND.
The probe tip will not withstand the force of winding copper wire around it.
Has anyone attempted to retrofit shielding into one of these? Obviously the first place to start is the PSU, but the main board is also pretty noisy.
While putting a box around the PSU is pretty straight forward, I'm concerned about the cooling. The fan arrangement is less than impressive. There's only 3/8" between the fan intake and the AFE shield.
