For example, if you choose to participate in write-on, you will be partially judged on the accuracy of your Bluebooking. Similarly, Bluebooking can provide anybody reviewing a writing sample an easy way to make a âfirst cutâ and divide applications between those that will get a closer look and those that will not.
A spectrum analyzer is a device used to examine the spectral composition of some electrical, acoustic, or optical waveform. Often, it measures the power spectrum.
Test setup. A spectrum analyzerâs ability to measure low-level signals is limited by the noise generated inside the spectrum analyzer. This sensitivity to low-level signals is affected by the analyzer settings.Figure 9, for example, depicts a 50 MHz signal that appears to be shrouded by the analyzerâs noise floor.
