It seems like the device under test would need to be rotated about two axes.?.?.?

gain is always 10*log (powerout/powerin) in units of dB. Performance is a function of geometric shape the environment and the applied field. Most satellite dishes I've seen are parabolic reflectors and are highly directional. The gains should be very high with this type of antenna. PS the...

Units of impedance are ohms. For reactive circuits like speakers, a given impedance only makes any sense when there is a frequency given with it. This means that the rated speaker impedance is only what is stated while measured at a certain frequency which is likely somewhere in the audio range...

You don't NEED a patent to sell your inventions. Just make sure you have your prior art well/legally documented. It can be helpful to have a patent if you think others will try to cash in on your idea which they most likely will if you are cashing in on it. Patents are expensive and are no...

Blues are the weakest link, besides the violets. There are many applications which want brighter blues. For example: my company (barcode decoders) is doing a cross hair targetting system in blue. I am always searching for brighter/ more efficient blues among other colors. Also, isn't it...

Random error frequency due to reactions from nucleon collisions with the circuit itself goes up with increasing cross sectional area. Dealing with that problem will cause costs to go up with circuit complexity. PS I thank the circuit characteristics at 60K feet thread for this even being on...

BPL is and should always stay illegal in this country if one takes existing FCC regulations literally. All of those power lines will make great antennas at the frequencies present in broadband internet traffic signaling. Not that I am opposed to the idea, it's just that they need to fix it first...

It is starting to sound to me like what you want will be very complex indeed. You may want to start studying up on control system theory and more specifically controlling servo motors as it is not a trivial thing. I find it highly unlikely that a canned approach will work, ie drop in this pic...

You don't give any explanation about what precision is necessary. For example: would manual motor full on full off open loop type control be suitable? do you need programmable motions? what kind of speed/position/acceleration error will be acceptable? I am also confused about where the robot...

Hi. One reason differential pairs are becoming more frequently found in high speed digital is the ability to create controlled impedance PCB layouts. This is becoming more important and necessary as signal rates climb and transmission line rules are taking over. There are other key benefits...
