But you found a sneak path
that looks like it might work, and it's still on grid.
In other words, whether the spectral component in question came directly from a frequency source, or was generated through a sneak path
of several mixers and subsequent amplification, SPECTRASYS identifies the component origin.
There is only one return path through each channel ground and no sneak path
or short circuits.
Poor matching can seriously degrade a device's spurious performance while uncontrolled ground currents, sneak paths
and waveguide moding can cause high level internal and external spurious responses.
