SignalShark 5G Analyzer V 1.0.0
The SignalShark 5G Analyzer consists of two measurement modules: The 5G EMF Extrapolation module makes it possible to determine the average level of a 5G resource element (RE). For this purpose, a downstream with maximum power is requested using a suitable user equipment (e.g. a smartphone). The SignalShark 5G Analyzer records an isotropic spectrogram and calculates the average level of a 5G resource element as well as the extrapolated maximum channel level. The SignalShark 5G Analyzer also provides a 5G `Smart Power Lock’ Test module with which the average level of a definable frequency channel can be determined using a moving average function. This Quick Guide explains how to install and activate the SignalShark 5G Analyzer software and it describes its views and how to operate the two measurement modules step-by-step.

Operation
Operating 5G EMF Extrapolation
Introduction
The SignalShark 5G Analyzer makes it possible to determine the average level of a 5G resource element (RE) and to extrapolate it to the entire signal. For this purpose, an isotropic antenna (3-axis-antenna) is connected to SignalShark. When starting a measurement, the device records spectrogram data for the given frequency span and time duration (i.e. period length and number of periods) on all three antenna axes. The recorded data will then be displayed as a spectrogram per axis. Within the recorded spectrograms the user can manually analyze the resource grid and set individual markers. In case of EMF measurements these markers will typically be set to moments of the strongest resource blocks. Based on the marker settings two calculations will be performed by the measurement module:
– The average level of one resource element within the marked area will be calculated (i.e. interpolated). – The average level of the marked area will be extrapolated to the complete signal as defined in the settings. As 5G may use extensive beamforming, it is essential that the above-mentioned measurement does not just represent ´any´ spatial measurement but that it represents a measurement where a 5G beam was pointing to the measuring unit. For this purpose, a downstream with maximum power needs to be requested. This can be achieved by using a suitable user equipment (e.g. a smartphone) that may work independently from the 5G Analyzer software. However, the software can also generate a downstream by means of a speed test which can be triggered simultaneously to the measurement and requires a suitable user equipment to be connected to SignalShark and using USB tethering for internet connectivity.
Data acquisition
1. Connect an isotropic antenna to the SignalShark. 2. In the SignalShark main user interface ensure that there is already one task (RT Spectrum or Scan Spectrum) running with any
settings. 3. Open the SignalShark 5G Analyzer by pressing the 5G button in the main menu. 4. In the Main View select the 5G EMF Extrapolation module 5. Tap on the settings button to open the settings dialog and adapt the settings according to the 5G signal to be measured, see also
sections 1.3.2 and 0 for details. 6. If you have selected the automatic speed test `librespeed’ in the settings, connect the SignalShark to a 5G-capable Android phone
via the USB 3.0 port (on top of SignalShark handheld unit) and activate USB tethering on the Android device. Make sure that the USB tethering is working properly, an appropriate RNDIS network is available and that your mobile phone contract supports 5G and provides sufficient data volume. 7. Tap on the `Start Measurement’ button (red recording icon in top tool bar). 8. In the pop-up window, enter the center frequency and select the frequency span. The span should be larger than the channel bandwidth of the 5G signal. The center frequency can also be read from the device if a 5G task is already present and properly configured. Then press `OK’.

Set marker range and save results
As indicated on the previous page, Marker A and B are used for determining the interpolated and extrapolated result level values. For handling the two markers, follow the procedure below: 1. Click on the ‘X-Axis’ tab to select the spectrogram for the X-axis measurement. 2. Select the largest possible area with maximum download traffic in the spectrogram with the markers. To do this:
a. click on the ‘Marker A’ button and then on the bottom left-hand corner of the area in the spectrogram. b. Then click on the ‘Marker B’ button to define the top right-hand corner of the marker area in the same way.
You can use the arrow keys (buttons and hard keys) to fine-tune the marker position. Press the OK button to switch between marker A and marker B. 3. Now switch to the next tab ‘Y-Axis’ and check whether the marker range you have just defined also fits here. 4. If the downlink does not fill the entire marker area, uncheck the ‘Marker Coupling’ checkbox and adjust the marker range for the Yaxis accordingly as described above. 5. Proceed accordingly for the ‘Z-Axis’ tab. 6. Check the marker ranges for all three axes again. 7. Finally, check the results (see next chapter) and save the measurement with disk icon in the toolbar. This also automatically creates screenshots for documentation purposes.
Read out result
The measured values and the extrapolated channel level can now be read in the results panel. The setting for the extrapolation can also be adjusted after the measurement if required. To do this, click on the `Settings’ button or in the results panel.
Lev.x(per RE): Received level per resource element for the X-axis in actual unit.
Lev.y(per RE): Received level per resource element for the Y-axis in actual unit.

Operating 5G `Smart Power Lock’ Test
Introduction
`Smart Power Lock’ is the ability of a 5G base station to temporarily exceed level levels (typically for a certain beam) so that the average allowed level (typically over the last six minutes as per EMF measurement standard) is still below the allowed maximum. With the 5G Smart Power Lock Test measurement module in the SignalShark 5G Analyzer, it is possible to monitor the RMS channel power of a 5G signal over several minutes and to calculate a moving average over a definable time (typically six minutes). During the measurement, the software automatically determines the maximum average level value. This value can then be compared with the EMF limit values. As 5G may use extensive beamforming, it is essential that the above-mentioned measurement does not just represent ´any´ spatial measurement but that it represents a measurement where a 5G beam was pointing to the measuring unit. For this purpose, a downstream with maximum power needs to be requested. This can be achieved by using a suitable user equipment (e.g. a smartphone) that may work independently from the 5G Analyzer software.
Data acquisition
1. Connect an isotropic antenna to the SignalShark. 2. In the SignalShark main user interface ensure that there is already one task (RT Spectrum or Scan Spectrum) running with any
settings. 3. Open the SignalShark 5G Analyzer by pressing the 5G button in the main menu. 4. In the Main View select the 5G Smart Power Lock Test module 5. Tap on the settings button to open the settings dialog and adapt the settings according to the 5G signal to be measured, see also
section Settings for details. 6. Tap on the `Start Measurement’ button (red recording icon in top tool bar). 7. In the pop-up window, enter the center frequency and select the frequency span. The span should be larger than the channel
bandwidth of the 5G signal. The center frequency can also be read from the device if a 5G task is already present and properly configured. Then press `OK’. 8. Wait until the measurement is finished. 9. While the measurement is running and after the measurement has been finished, results as exemplarily shown on the following pages may be displayed. With regards to these measurement examples, the following notes shall be considered:
a. While the measurement is running, an additional window is displayed showing the current isotropic RMS spectrum and the selected channel bandwidth. This window can be moved if necessary, but it will be displayed as the topmost window.
b. The red area in the main diagram is set automatically indicating the maximum average. The width of this area is defined by the averaging time.
c. The blue area in the main diagram displays the current basis for averaging. It moves forward while the measurement is running and it can be moved manually by drag & drop when the measurement has been finished.
d. The green bar on the right side indicates when the full averaging time has been reached. e. The green ACT trace in the main diagram displays the current isotropic RMS level related to the defined CBW (i.e.
integration of RMS spectrum) f. The violet AVG trace in the main diagram displays the moving average isotropic RMS level related to the defined CBW
and to the defined averaging time. The peak of that trace serves as reference for the red area, supposing the averaging time has been fully reached.
