3-3 Spectrum Monitor GUI Overview Spectrum Monitor Measurements Spectrum Monitor GUI Overview This section illustrates the main graphical displays and menus presented for the spectrum monitor. Normal Spectrum View Normal Spectrum view is the default view and is suitable for viewing signals in the frequency domain where signal amplitude, bandwidth, and harmonic qualities can be studied.
Page 57 Spectrum Monitor Measurements 3-3 Spectrum Monitor GUI Overview 1. Status Panel: Each measurement features a unique status panel that displays settings and information relevant to the current measurement and view settings. 2. Markers: Markers are displayed as green diamonds on the trace to which they are assigned. The active marker is shown as a solid green diamond with a dashed vertical line.
Page 58: Spectrogram View
3-3 Spectrum Monitor GUI Overview Spectrum Monitor Measurements Spectrogram View Spectrogram view is useful for identifying intermittent signals and for providing historical signal data in a comprehensive view. It provides a multi-dimensional “waterfall” display representing frequency, time, and amplitude. Frequency and time are shown on a typical two-dimensional scale while amplitude is displayed in the color dimension.

3-7 Setting Frequency Parameters Spectrum Monitor Measurements Setting Frequency Parameters Frequency-related parameters are set using the “FREQ / SPAN Menu” on page 3-11. 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 63: Using Offset Frequency
Spectrum Monitor Measurements 3-7 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 monitor in order to display the actual received antenna frequency in the sweep window.
Page 64 3-7 Setting Frequency Parameters Spectrum Monitor Measurements The normal IF BW uses analog bandpass filters in the normal RBW chain. By changing the RBW, different filter bandwidths are selected. While the IF bandwidth is influenced by the selection of RBW filters, the digital RBW filters themselves are not employed.

Spectrum Monitor Measurements 3-8 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 3-12 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.

3-8 Setting Amplitude Parameters Spectrum Monitor Measurements AMPLITUDE 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. Clicking the plus (+) or minus (–) control increments the value by 10. The plus/minus (+/-) button on the keypad toggles between positive and negative values.
Page 73: Setting Bandwidth Parameters
Spectrum Monitor Measurements 3-9 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 monitor 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.

Spectrum Monitor Measurements 3-12 Setting Up Markers Marker Functions Noise Markers Noise Markers use an averaging routine applied to multiple data-point groups to calculate the readout, which is typically comparable to using 1 Hz bandwidth filtering. Because the noise marker routine uses groups of data points for the calculation, the noise marker should not be placed in close proximity to measurable signals.

If the selected marker is on, then it will become the active marker and any subsequent actions in the PEAK SEARCH menu will apply to the selected marker.
Page 199 5GNR Measurements 5-9 Setting Up Markers Marker Functions Noise Markers Noise Markers use an averaging routine applied to multiple data-point groups to calculate the readout, which is typically comparable to using 1 Hz bandwidth filtering. Because the noise marker routine uses groups of data points for the calculation, the noise marker should not be placed in close proximity to measurable signals.

The feature attains the magnitude/phase or real/imaginary raw data components of a waveform and either saves the data to a file on internal or external USB storage media, or streams the data out of the Data, USB, or Ethernet ports.
Page 232: Iq Frame Structure
6-3 IQ Data Format IQ Capture/Streaming (Option 124/125 and 126/127) IQ Frame Structure IQ data is organized into two levels: frame and extended frame. The lowest level is a 64 bit frame. which may contain one to four IQ sample pairs depending on the selected IQ bit resolution. The second level is an extended frame which can be used for the stamp information.
