Trace Data Limits
The displayed amplitude of each trace element falls in one of 601
vertical data points. See Figure 5-10. There are an additional 10 points
of overrange. The spectrum analyzer clips results that exceed these
limits. The overrange is equal to one-sixth of a division above the
reference level. Also, the same clipping algorithm is applied to
correction data in a trace (for example, correction data that you enter
into trace B). For example, if the reference level is 0 dBm, the scale is
equal to 10 dB per division; therefore, the correction values must be
within the range of +1.66 dBm to −100.00 dBm (one-sixth of 10 dB is
equal to 1.66 dB).
