ESG Family Signal Generators Initial Troubleshooting and RF Block Diagrams Equipment Required for Troubleshooting Equipment Required for Troubleshooting Table 1-2 lists the equipment required to troubleshoot your signal generator. You may use the recommended model or an equivalent that meets the critical specifications.
Initial Troubleshooting and RF Block Diagrams Initial Troubleshooting ESG Family Signal Generators Initial Troubleshooting Perform the following troubleshooting steps in the order they are presented. If you are unable to identify the failed assembly, go to Chapter 2, “Assembly-Level Troubleshooting with Block Diagrams,” for further instruction. NOTE Do not attempt to replace any fuses within the power supply to correct a problem with your signal generator.
ESG Family Signal Generators Initial Troubleshooting and RF Block Diagrams Initial Troubleshooting Step 2: Power On the Signal Generator and Check for Error Messages This procedure verifies that the signal generator powers up and that the internal instrument check identifies no errors. The internal check evaluates the correctness of operation and returns an error message if a problem is detected. 1. Switch on the signal generator. Let the signal generator warm up for at least five minutes.
Initial Troubleshooting and RF Block Diagrams Initial Troubleshooting ESG Family Signal Generators Step 3: Functional Check the Front Panel Keys and Display 1. Press various front panel hardkeys and softkeys to verify they function as expected. 2. Use the contrast keys to verify that the display can be lightened and darkened. Refer to Figure 1-2.
ESG Family Signal Generators Initial Troubleshooting and RF Block Diagrams Initial Troubleshooting Step 4: Visually Check the Individual Voltage Supplies 1. Unplug the signal generator and remove the instrument cover. Refer to Chapter 5, “Assembly Replacement,” for removal instructions. 2. Expose the motherboard by removing the top cover. It is secured by 11 screws. 3. Plug in the signal generator and allow it to warm up for at least five minutes. 4. If possible, clear the error queue(s) of messages.
Initial Troubleshooting and RF Block Diagrams Initial Troubleshooting ESG Family Signal Generators Step 5: Measure the Individual Voltage Supplies The voltages supplied as inputs from the power supply via J6 to the motherboard are +15 V (TP502), +15 V standby (+15 V_STBY), −15 V (TP503), +12 V (TP505), and +5.2 V (TP302). DGND (TP301) is associated with these supplies. The −6 V (TP508) and −5.2 V (TP509) supplies receive their input from the +5.2 V digital supply (5.2 VD at TP506). The +5.
