Spectrum Analyzer Measurement Guide : Spectrum Analyzer Measurements : Connecting a Signal Source
 
Connecting a Signal Source
The basic setup starts with connecting a signal source to the RF IN port of the instrument. For over-the-air measurements, connect an antenna that is appropriate for the frequency range to be measured. For direct conducted measurements, ensure the RF source does not over power the input of the analyzer.
Note 
For connector panels descriptions and torque specifications, refer to the product user guide. For RF input power limitations, refer to the product technical data sheet.
After an RF source is connected to the input connector, follow the sections below for setting up the measurement parameters.
