Overload detection and Power Trip function is a safety feature to protect your E5071C from over-input. When an overload is detected, the power output is automatically turned off by the power trip feature. If the power output is turned off by the power trip, remove the cause of the over-input and turn on the power output to restart the measurement .
When you make a measurement at the frequency between 9.375 MHz and 8.5 GHz, an overload may occurs even if the input signal level is below the maximum input level. In that case, you may turn off overload detection. Even if the overload detection is turned off, overload may occur at the excessive input level.
When you need to turn off this feature, be sure to control that your input signal is under the maximum input level for specified measurements, and never exceeds the damage level (26 dBm) written on the instrument panel, or the instrument is damaged.
