Peak detection

One way to insure that all sinusoids are reported at their true amplitudes is to display the maximum value encountered in each bucket. This is the positive peak detection mode, or peak. This mode is illustrated in Figure 2-22b. Peak is the default mode offered on many spectrum analyzers because it ensures that no sinusoid is missed, regardless of the ratio between resolution bandwidth and bucket width. However, unlike sample mode, peak does not give a good representation of random noise because it only displays the maximum value in each bucket and ignores the true randomness of the noise. So spectrumanalyzers that use peak detection as their primary mode generally also offer sample mode as an alternative.

23Negative peak detectionNegative peak detection displays the minimum value encountered in each bucket. It is generally available in most spectrum analyzers, though it is not used as often as other types of detection. Differentiating CW from impulsive signals in EMC testing is one application where negative peak detection is valuable. Later in this application note, we will see how negative peak detection is also used in signal identification routines when you use external mixers for high-frequency measurements.

Normal DetectionTo provide a better visual display of random noise than offered by peak mode and yet avoid the missed-signal problem of the sample mode, the normal detection mode (informally known as rosenfell9 mode) is offered on many spectrum analyzers. Should the signal both rise and fall, as determined by the positive peak and negative peak detectors, the algorithm classifies the signal as noise. In that case, an odd-numbered data point displays the maximum value encountered during its bucket. And an even-numbered data point displays the minimum value encountered during its bucket.Define channels

H tr ti a 20 knhAttenuation ModeMaximum found on full scan: a first scan will be done for every session, the attenuation will be then defined depending on the maximum level found. This mode is recommended when little information on the scanned zone are available.Attenuation checked on selected bands: a first scan will be done on every band defined in the scenario; this mode is recommended when a few bands only are scanned and the measurements are made close to a transmitter (frequency and types already known).Constant attenuation: the attenuation is constant and selected manually. This mode is recommended to perform many measurements in a restricted area, far from any transmitter.Attenuation is placed between RF Input of the analyser and the mixer to avoid damage on the mixer. It helps to measure high power signals and preventsthe analyser to suffer damages (even if a band is not scanned). The attenuation should be constant for all the measurements.
