You need to increase the sample value.
Using the two values version may help.
Have the pretrace go deeper.
As for the count, use the two values version for nearest_count.

Try this version :

global_settings {
  assumed_gamma 1
  #if (Radiosity)
   radiosity {
    pretrace_start 0.04
    pretrace_end 0.0025 // or even 0.00125
  // more pretrace sampling almost always reduce noise and artefacts.
    count 350 999 // Should reduce those dark splotches.
  // Second value set a sampling direction pool.
  // Second value MUST be greater than the first
    recursion_limit 2 // 1 may even be enough.
    nearest_count 20 5 // enable adaptive sampling and pretrace
  // second value must be the smaller one.
  // Larger first value often help to reduce the dark splotches,
  // and also make then less sharp.
    error_bound 0.35

Try raising the oscilloscope a little bit above the table. After all, 
most have rubber pads under them acting as short legs.
