After a thorough investigation, the team initiated a RAMEC to filter the chip detector from spurious emissions from other sources that cause a false signal through EMI.
It is ideal for the measurement of harmonic and spurious emissions, identification of unknown or unwanted signals, signal monitoring, field strength measurements and EMC precompliance testing.
To gain licenses in the United States and some other countries, Iridium pledged that for a few hours each day, it would keep the levels of spurious emissions to levels tolerable to the scientists.
The frequency bandwidth can be selected by the operator to achieve low spurious emissions. These properties allow wideband frequency coverage with only one unit, whereas other approaches, i.e., fixed block converters, require several different block converter modules.
In wireless design, things like receiver self-quieting where your receiver can't hear what it's supposed to because your memory bus is screaming in its face like a drill sergeant or intentional radiator spurious emissions where you're transmitting on frequencies you don't intend and are not allowed pose great challenges.
* Panorama scan mode is used as a "quasi spectrum analyzer" for a wide scanning range without scanning - as the PR100 Series uses a receiver technology that does not scan, but rather listens to the entire spectrum to immediately detect any spurious emissions. Step size, start/stop frequency and sampling analog RF panorama scan resolution can be set.
The transmit limit for harmonics and spurious emissions is 80 dB below the fundamental frequency amplitude except for the 2nd and 3rd harmonics.
The filter is used for harmonic rejection at the transmitter output to eliminate spurious emissions. The housing is robust with plenty of heat sinking and uses one-piece silver-plated connectors that are screwed and soldered to the filter housing.
All other harmonic and spurious emissions must be suppressed by 80 dB.
CAN bus chokes minimize spurious emissions from automotive electrical systems and suppress interference with on-board electronics.
