Subject: Re: [PSES] EMC test lab errors

I'll dare to mention a few errors which I have seen first-hand; I would say 
that these are all in the "we don't know what we don't know" category.

* Having an abiding faith that mixers can handle any power you push down a coax.
* Thinking that coaxial directional couplers are as broadband as the coax.
* Assuming that components must blow smoke before death.
* That amplifiers only amplify.
* That signal sources are clean.
* Not realizing that coax cables are not water pipes, and that stacking several 
3-way Tees at a junction will have no effect on impedance.
* That anything performs as promised without cross-checking.
* That what was good last week is still good.
* That the little mistake you made earlier couldn't have any cascading effects.
* That the software knows what it's doing.
* That you know what the software is doing.
* That you have all the variables under control.
* That everyone wants to know the truth.
