1. The attenuator can only withstand a maximum power of 1W (CW), so do not input power exceeding 1W (CW) into the attenuator port at this time.
2. The programmable step attenuator port is a precision female connector that can only be connected to a matching connector. When connecting, attention should be paid to whether the size of the port to be connected meets the national standard requirements to avoid damaging the connector and affecting the device's specifications and service life. In addition, it is best to use a torque wrench when connecting and disconnecting connectors. Cover the connector with a dust cap when not in use to prevent excess material from entering the attenuator and affecting the performance indicators.
3. The programmable step attenuator is a non sealed attenuator, please store it in a dry and dust-free environment.
