The 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. The internal frequency range is 10MHz to 22GHz. Preset the unit 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.
