The spectrum analyzer performs frequency sweep within the set frequency range. Whenever the frequency parameters are changed, the frequency sweep is restarted. There are two ways to indicate the frequency range of the current channel of the spectrum analyzer: start frequency/end frequency, center frequency/span.
  • Page 56 S3532 / S3533 Series Spectrum Analyzer User Manual In zero span mode, the start frequency, center frequency, and stop frequency have the same  value and will be modified together. You can use the numeric keys, knob, and arrow keys to modify this parameter. ...

  • Page 57: Frequency Offset

    S3532 / S3533 Series Spectrum Analyzer User Manual This function is very useful for quickly adjusting the center frequency to the harmonic of the input signal. For example: Observe the harmonics of a 300MHz input signal, set [Frequency Step Automatic Manual] to Manual, and enter 300MHz. If the center frequency is 300MHz at this time, press the step increment key to change the center frequency to 600MHz, which is equal to the second harmonic.

  • Page 58: Ampt

    S3532 / S3533 Series Spectrum Analyzer User Manual When changing the span in non-zero span mode, if the frequency step and RBW are i  automatic mode, the frequency step and RBW will be automatically modified, and the modification of RBW will cause the change of VBW (in automatic mode). Changing any one of the span, RBW and VBW will cause the change of sweep time.

  • Page 87: Using Resolution Bandwidth To Resolve Closely Spaced Signals

    S3532 / S3533 Series Spectrum Analyzer User Manual 4.2 Using resolution bandwidth to resolve closely spaced signals Resolution bandwidth description: The signal resolution is determined by the bandwidth of the intermediate frequency (IF) filter, i.e., the resolution bandwidth. When a signal passes through the IF filter, the spectrum analyzer uses the signal to scan the bandpass shape of the IF filter.
