Elecraft XG3 RF Signal Source

摘要

There are four momentary contact push buttons: the BAND (+) and BAND (-) buttons, the ON/OFF power button and the output LEVEL button. The 0 dBm indicator will flash when the internal 9 V battery falls below a measured 7.6 V, or if an external supply falls below 11 V. A BNC type connector is used at the RF output. At the ARRL Laboratory, I must always be mindful of these safety steps! I also tum the RF output and the microphone gain to minimum with any transceiver I test as an added precaution.
