Figure 5: AFG output circuits
The following table shows the output window (minimum and maximum levels) for a sine waveform
when you change the load impedance (L). Load impedance affects the output window.

Protection from overheating
The internal temperature of the AFG31000 Series instrument is monitored. A warning message is
displayed if the internal temperature reaches a specified level and signal output is automatically
turned off.
If the warning message appears, check for the following conditions:
 The ambient temperature requirement is correct.
 The required cooling clearance has been provided.
 The instrument fan is working properly.
