In most areas that do emissions testing today, a simple plug-in OBD II test is used to check emissions on 1996 and newer vehicles. The plug-in test checks to see that the vehicle's OBDII system is functioning normally, that all the requires self-checks have been completed, and that they...
The test lab will scan the frequency band of interest and look for emissions that are close to the limits. Using a process called 'maximization' (described below), the test lab focuses in on each of these emissions, and quantifies the amplitude of the field strength. Class A digital devic...
In the same way, the maximum field strength at the antenna will be at some particular height. A full compliance test lab needs to move the antenna up and down a 4 or 6 meter antenna mast to make sure it has found the point where the field strength is at a maximum. Again, moving th...

That’s why the proposal includes a new low-load-cycle test procedure, among others. EPA said the proposed regulations can be thought of in three broad categories: controlling emissions under a broader range of engine operating conditions, maintaining emission control over a greater portion of an...

Assure the support equipment is not at fault. Turn it off, if you can, without turning off significant portions of your equipment under test. If that can’t be done, attempt to reverse that, and turn off the equipment under test, while leaving the support equipment on. Does the problem ...
A wave travelling through a TEM cell has a free-space impedance of approximately 377Ω (up to an upper frequency boundary), which happens to be the impedance of a far-field plane wave propagating in free-space. In an OATS (open area test site) or a semi-anechoic chamber, the measurement...
CO2emissions are transformed to stationary by computing their annual growth rates,yt=ln(et)−ln(et−1). The right panel of Fig.1plotsytwhile Table1reports some descriptive statistics. We can observe that, according to the non-stationarity test proposed by Dickey and Fuller (1979),ytis sta...
