  • Page 19 Spectrum Analyzer Measurements 3-1 Introduction Chapter 3 — Spectrum Analyzer Measurements Introduction The purpose of this chapter is to provide a starting point for making basic spectrum measurement setups. This chapter describes general instrument setup, including setting up frequency, bandwidth, amplitude, span, limit lines, and markers.
  • Page 20 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 Spectrum Analyzer Measurements 3-3 Setting Frequency Parameters Both positive and negative offset values are allowed. Negative offsets can be useful for seeing differences from expected values. Enter a negative offset of the expected value, and the received antenna frequency should display in the 0 Hz range.
  • Page 22 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.

The instrument supports both log units (such as dBm and dBV) and linear units of scale (such as volts or watts). Amplitude-related parameters are set using the “AMPLITUDE Menu”...
  • Page 28 3-4 Setting Amplitude Parameters Spectrum Analyzer Measurements Setting Amplitude Reference Level The amplitude reference level is typically an absolute reference level set at the top of the graticule for the power level being measured. Signal levels above this set value will be outside of the display range and may overdrive and saturate the input circuit (refer to “Indications of Excessive Signal Level”...
  • Page 29 Spectrum Analyzer Measurements 3-4 Setting Amplitude Parameters Preamplifier The preamplifier can be turned on and off by toggling PRE AMP via the status panel or the AMPLITUDE menu. Figure 3-5 shows the noise floor with the preamplifier off (1) and on (2). Note that when the preamplifier is turned on, the noise floor drops significantly and a low-level signal is exposed.
  • Page 30 3-4 Setting Amplitude Parameters Spectrum Analyzer Measurements Indications of Excessive Signal Level The instruments have built-in features to help prevent input overload. These include auto attenuation and reference level. The instrument will also indicate when a received signal is too high for the current setup by displaying an “ADC Overrange”...
  • Page 31 Spectrum Analyzer Measurements 3-4 Setting Amplitude Parameters AMPLITUDE Menu Access AMPLITUDE menu from main menu. REF LEVEL: The reference level is the top graticule line on the measurement display. If the reference level offset is not zero, the offset reference level is displayed at this location.
  • Page 32 IMPEDANCE: Select either 50 Ω, 75 Ω, or Other. Selecting 75 ohm selects the 7.5 dB loss of the Anritsu 12N50-75B adapter. For other adapters, select Other and enter the appropriate loss (0 dB is the default loss). Note that loss values are also applied to the relevant units.
  • Page 33 3-5 Field Strength Field Strength The field strength measurement is used in conjunction with an Anritsu antenna that has known antenna factors. Users can also import custom antenna factors for antennas not listed in the standard antenna selection list. When the field strength measurement is enabled, an additional plot is shown at the bottom of the display, indicating the selected antenna factor over the currently set frequency span.
  • Page 34 3-5 Field Strength Spectrum Analyzer Measurements 1. When the field strength measurement is enabled (2), all amplitude units are converted to display field strength in the selected units. 2. The field strength measurement and antenna is selected from the AMPLITUDE menu. 3.

  • Page 37 Spectrum Analyzer Measurements 3-6 Setting Bandwidth Parameters Setting Bandwidth Parameters Bandwidth parameters are set using the “BANDWIDTH Menu” on page 3-21. Resolution Bandwidth Resolution Bandwidth (RBW) determines frequency selectivity. The spectrum analyzer traces the shape of the RBW filter as it tunes past a signal. The choice of resolution bandwidth depends on several factors. Filters take time to settle.
  • Page 38 3-6 Setting Bandwidth Parameters Spectrum Analyzer Measurements Setting Frequency Bandwidth Select BANDWIDTH on the main menu. Toggle AUTO RBW or AUTO VBW (or both) off to manually change values. If using Auto, refer to the following sections. Set the RBW and VBW to achieve the desired resolution and sweep characteristics. Lower values increase resolution and reduce noise, but at the expense of measurement (sweep) speed.
  • Page 39 Spectrum Analyzer Measurements 3-6 Setting Bandwidth Parameters BANDWIDTH Menu Access BANDWIDTH menu from main menu. AUTO RBW: When toggled on, the instrument selects the resolution bandwidth based on the current span width. The ratio of span width to RBW can be specified using the SPAN:RBW button.
  • Page 40 3-7 Setting Trace Parameters Spectrum Analyzer Measurements Setting Trace Parameters The instrument can display up to 6 traces simultaneously. Traces can be enabled from the TRACE menu by selecting the trace from the available selections, or you can select a trace in the Status panel to make it active. Each trace can have a separate trace type, mode, and detector.
  • Page 41 Spectrum Analyzer Measurements 3-7 Setting Trace Parameters Trace Math in RF Spectrum View The figure below shows the instrument with trace 5 and 6 enabled on a signal, each with a different trace or detector type setting. The left side status panel shows a trace setup summary table. Touching one of the trace rows in the table will enable the trace and open the TRACE menu.
  • Page 42 3-7 Setting Trace Parameters Spectrum Analyzer Measurements Trace Normalization in RF Spectrum View The purpose of trace normalization is to bring the measured traces onto a common scale, allowing meaningful comparisons between different traces or measurements taken at different times or locations. By normalizing the traces, you can effectively remove the influence of factors such as different instrument sensitivities or attenuations, ensuring that the relative amplitudes of signals in the spectrum are accurately represented.
