The tuning frequency range can be entered in several different ways depending upon what makes the most sense, either for the user or for the measurement.

  • Page 19: Using Offset Frequency

    Making Spectrum Analyzer Measurements 3-3 Setting Frequency Parameters Using Offset Frequency A user-defined frequency offset can be entered to adjust the frequency that is displayed on the instrument from the actual swept frequency. For example, if the DUT is an antenna system receiving signals in the 10 GHz range and offsetting the signals to the 1 GHz range, you can set a frequency offset in the spectrum analyzer in order to display the actual received antenna frequency in the sweep window.

    3-3 Setting Frequency Parameters Making Spectrum Analyzer Measurements Zero Span IF Output (Option 89) Zero Span IF output effectively allows the spectrum analyzer to be used as a receiver front-end, converting the input signal at the spectrum analyzer RF In connector to a signal centered at the IF output frequency. You can then process the IF signal in a way that meets your needs.
  • Page 21 Making Spectrum Analyzer Measurements 3-3 Setting Frequency Parameters The spectrum analyzer has several mixer bands.
