Good idea with this list. COme on guys, let's get
Um..... here's mine
If you're looking
at a spectrum analyzer display and see a spectral
line and you need to determine whether it's a discrete
spur, try increasing or decreasing the resolution
BW control. If the noise floor power level changes
but the amplitude of the spur does not, then it's
a discrete spur.
I'm amazed at the numbe
rof guys I work with don't know that simple test.
The reason it works is because a discrete spur has
no significant content other than at its discrete
frequency, so the BW of the filter does not affect
its power level (as long as your signal is not on
the skirt (band edge) of the filter.
way, that's mine. Let's have more.............
