2.15.2 Precautions When Using Bias-T
When connecting an external device such as a Bias-T to the output
connectors of the BERTWave, if the output signal includes any DC
voltage, variations in the output of the DC power supply or load may
change the level of the output signal, risking damage to the internal
circuits.
CAUTION

Do not connect or disconnect any external devices
while DC voltage is impressed.

Only switch DC power sources ON and OFF when all
equipment connections have been completed.
