  • Page 20: Setting Frequency Parameters

    3-3 Setting Frequency Parameters Spectrum Analyzer Measurements Setting Frequency Parameters Frequency-related parameters are set using the “FREQ / SPAN Menu” on page 3-6. 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 21: Using Offset Frequency

    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.

  • Page 22: Zero Span If Output (Option 89)

    3-3 Setting Frequency Parameters 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 23 Spectrum Analyzer Measurements 3-3 Setting Frequency Parameters The spectrum analyzer has several mixer bands. Depending on the operating frequency, the local oscillator may be above or below the input frequency. When the local oscillator frequency is below the input frequency, an increase in the input frequency results in an increase in the IF output frequency.
