A signal source is connected to the spectrum analyzer input. The
analyzer steps through the bandwidths from 3 MHz to 10 Hz, centers
the signal, sets signal peak near the reference level, and measures
the frequency of the 3 dB points for each bandwidth. The 3 dB
bandwidth is then calculated by determining the difference in
frequency between the 3 dB points.
Next, the spectrum analyzer steps through the bandwidths and
measures the frequency of the 60 dB points of each bandwidth. The
60 dB bandwidth is then calculated by determining the frequency
difference between the 60 dB points.
The shape factors are calculated by dividing the 60 dB bandwidths by
the 3 dB bandwidths.
This procedure is for instruments other than those having Option 462.
For Option 462 instruments perform the test on the following page.
