Troubleshooting Assembly Level Problems
Power Supplies
The power supply is a switching supply that has an automatic line-voltage and frequency selection. There are
no switches to change for 115 Vac or 240 Vac operation. The power line fuse is not replaceable. If the fuse
opens, the power supply must be replaced. Use the Power Supplies vs. Assembly Matrix
(Table 1-13 on page 1-18) to troubleshoot the signal generator’s power supplies.
WARNING Wait 30 seconds after unplugging the instrument to allow the supplies to discharge
before removing or installing any assemblies.
