1. Purpose & Scope 

The purpose of this document is to describe the guidelines and main 

building blocks for the ASUS Hermon repair tool. The document describes the 

calibration process required for repairing and measuring the phone 

functionality. These calibration processes consist of a set of independent 

calibration procedures, however we need to initialize the IFL (Intelligence 

Framework Libraries) first before we use them. 

The document will focus on the GSM system and introduce how to use the 

repair tool for repairing and measuring the phone functionality. The outcome of 

the calibration process is a set of parameters that shall be loaded two 

databases on the PC and on the phone. 

 

2. Hermon Repair Tool Hierarchy 

 

 

 DLL Module：(build with Visual C++) 

  Base on HMDSender.dll and reference Intel HTS 2.01 source code   

 Application Side：(create by C++ Builder) 

  User interface   

  Combine the export functions and test procedures 

  Show result and information 

 Hermon repair tool features the following capabilities： 

  Flexibility. (easy to add extended functions or create new method by 

update DLL module) 

  Auto identifies USB connection between application tool and target         

board. 

  Set and control UE in difference mode. (production mode/operational 

mode) 

  GSM system  –  preliminary finish TX/RX debug functions. 

  Embedded other useful function in repair tool. 

 

3. General Description

 

 

The Hermon software has two main states as shown in below. 

 

There are two main operating modes, 

  Operational Mode 

  Default operating mode. 

  Normal operation of the system. 

  Production Mode (Calibration Mode) 

  Production mode is used mainly for calibration activities, thus no 

call processing activities are required. 

  This mode can be entered only after reset (or wake-up). 

This mode requires the system to disable the protocol stack that the 

external control software (e.g. ICAT or Hermon Repair Tool) will 

manage the system; it will communicate with the DIAG module. 

 

4. System Block Diagram

 

 

Following are the main test procedures: 

  System wakeup 

  Test equipment initialization 

  Scenario initialization 

  Acquisition 

 

 

 

 

Application Side： 

Following figures are the scenario of operating guidelines. You can refer to the 

main building blocks in the below too. 

1. Start the program and power on the target then wait the device connection. 

 

2. Update database 

 

4. Fill out the data then press following button：turn off protocol

select band 

mode

set calibration mode 

 

5. Run the test scenario： 

TX – Remember press STOP button when you finished TX. 

RX – You can select LNA Control option before press START button.
