SNR measured by UE can be logged into a text file in a format expected by the NetSim metrics window. Upon adding a reference to the SNR plot text files in the Metrics.xml file we can conveniently obtain SNR plots in the NetSim Metrics window without having to use other tools like MS Excel, GNU Plot, etc. Following is one such example where we log the SNR for each UE in a separate text file and obtain plots in the NetSim Metrics window at the end of the simulation.


The steps involved may vary between different versions of NetSim. Choose the appropriate section of this article, as per the version of NetSim (please scroll down to see the different version applicability).



Applicable Releases
v13.3


SNR can be seen in LTENR_Radio_Measurement log file in the NetSim results dashboard. LTENR_Radio_Measurement log file can be enabled from logs from the toolbar in the NetSim GUI.


We can obtain SNR Plot for each UE using tools like MS Excel. The steps to plot the graph are as follows:

  1. Filter the channel column to PDSCH because the network has downlink traffic.
  2. Select the Time (ms) column and SNR (dB) column from the excel sheet and click on the insert option from the toolbar.
  3. From the Insert option click on charts > scatter with smooth line option to get SNR vs. Time plot.



Applicable Releases
v13.2


SNR can be seen in LTENR_Radio_Measurement log file in the NetSim results dashboard. LTENR_Radio_Measurement log file can be enabled by referring to the section  3.19 of NetSim 5GNR technology library manual.


We can obtain SNR Plot for each UE using tools like MS Excel. The steps to plot the graph are as follows:

  1. Filter the channel column to PDSCH because the network has downlink traffic.
