This situation typically arises when changing the voltage unit setting, such as switching to dBm. The dBm unit is only valid for a 50 Ω output impedance, so if you select dBm while the output impedance is set to High Impedance, the system will automatically revert the impedance back to 50 Ω to ensure accurate voltage and power calculations.
