The Agilent 8569A Microwave Spectrum Analyzer provides an excellent sensitivity and internal preselection assuring a wide, spurious-free measurement range which is necessary for production applications, while the digital display and coupled controls speed measurement routines. 
Preset the 8569A to the color-coded, "basic operation", settings and use the coupled controls to make most measurements in three easy steps: tune to the signal, select a span and raise it to the reference level.
