The Anritsu TETRA Signal Generator provides you with a PC utility to quickly create a T1 TCH/7.2 test signal for Base Station sensitivity testing as per the TETRA test specification to be used with the Anritsu LMR Master S412E handheld instrument. To begin using the utility, install the software, enter your signal pattern parameters into the dialogs, and then save the generated signal pattern file for importing into your LMR Master.
This document also provides the necessary instructions on how to generate custom TETRA DL patterns, and to load these new patterns into LMR Master S412E. This feature is to be released in November, 2021. Refer to Installing the TETRA DL Signal Generator Software.
Required Hardware and Software
• LMR Master S412E with TETRA Analyzer (Option 581) upgraded to firmware 4.40
• Windows 10 computer
• USB Memory Device formatted using FAT32 file system
• Internet Connection

Installation Complete Window
Installation is now complete and the TETRA Signal Generator is now ready to run.
Running the TETRA Signal Generator
1. If you have added a shortcut to your desktop, you can double click it to run the program.
The TETRA Signal Generator can also be found under the Windows Home/All Programs menu under TetraSignalGenerator.
2. Enter the desired values for Base Color Code (BCC), Mobile Network Code (MNC), Mobile Country Code (MCC), and Number of Multi-Frames, and then click [Generate Signal] button to generate your desired signal.
Note
Do Not leave any field empty. Each field must contain an integer value within the specified range.

3. Select the Folder where you want the signal file to be placed and click [Select Folder].
Note
Depending on the processor and Number of Multi-Frames selected, this process may take up to 30 minutes. Do Not cancel the signal generation process or the program may hang and need to be restarted.
Four files will be generated. The signal file that will be used in the S412E will be named:
TETRA_T1_TCH_7p2_{BCC}_{MCC}_{MNC}_{#MF}_.bin
Note
Do Not rename the .bin file as the S412E will expect the .bin file to have a specific naming convention.
Where:
• {BCC} = Base Color Code
• {MCC} = Mobile Country Code
• {MNC} = Mobile Network Code
• {#MF} = Number of Multi-Frames
For more information on loading and testing custom base station patterns, refer to BS Sensitivity Menu section of the Land Mobile Radio Analyzer and Coverage Measurement Guide (10580-00243AE-LMR-MG).

3. Select the Folder where you want the save the custom pattern and click [Save] button.
Note
Depending on the processor and Number of Multi-Frames selected, this process may take up to 30 minutes. Do Not cancel the signal generation process or the program may hang and need to be restarted.
Saving the Generated File
4. When the custom TETRA pattern is generated the pattern’s name will be displayed as.txt file in the Status box.

5. Locate the .txt file and copy it to a USB memory device.
Importing Custom TETRA DL Patterns
1. Power On the LMR Master S412E and wait until it finishes its power-up sequence.
2. Insert the USB memory device with TETRA pattern in the root directory.
3. Select the TETRA Analyzer Mode.
4. Once the TETRA Analyzer mode is loaded, select Setup using the soft key at the bottom of the screen. Select the "Load Custom DL Pattern" button on the right edge of the screen.
Loading Custom DL Pattern
5. Locate the USB memory device and select the .txt file containing the TETRA pattern. Once highlighted, press the Enter key on the instrument.
Locating the TETRA file on the USB Memory Device
6. Press the Enter key on the instrument when prompted with LOAD PATTERNS message, to start loading the patterns.
Loading the DL Patterns
7. The custom pattern will begin loading and can take up to three minutes to complete. When done, press the Escape button on the instrument to exit.
Successful loading of the DL Patterns
8. Select CUSTOM PATTERN INFO from the Setup menu to confirm successful loading of the custom patterns.
Pattern Info Verification
9. Press TX PATTERN from the Setup menu, and select CUSTOM DL option when PATTERN TYPE SELECTOR appears.
10. Ensure the instrument's TX frequency matches the center frequency of the pattern and the amplitude is appropriate for the test. The pattern generated as shown below was made possible by connecting the signal generator output of the S412E to its Analyzer/RF In port. Note that the TETRA summary matches with the parameters set using the TETRA DL SIGNAL GENERATOR software.
