Getting Started with Troubleshooting
WARNING Immediately unplug the signal generator from the ac power line if the signal generator shows any of the following
symptoms:
• smoke, arcing, or unusual noise from inside the signal generator
• a circuit breaker or fuse on the main ac power line opens
If this rare symptom occurs it’s a potentially hazardous condition. Do not try to repair, instead, return the signal
generator to Agilent Technologies.
CAUTION For the instrument to meet performance specifications and for accurate self-test results, allow a warm up period of 45 minutes
within an operational temperature range of 0 to 55 °C. For more information, refer to the MXG signal generator Data Sheet.
