It is forbidden to load the input port with a signal that does not meet the rated value, and
ensure that the probe or other connected accessories are effectively grounded to avoid
equipment damage or abnormal function. RF IN port can only withstand an input signal power
of no more than +30dBm or a DC voltage input of 50V.
7. Gen Output 50Ω （Tracking Source） : This N- Female connector is used to as the source output of
the built-in tracking generator. The input impedance is 50Ω.
Warning
It is forbidden to load input signals on the output port to avoid damage or abnormal function.
