In this screen shot the output power can be set by means of NEW F. PW adj.. The resolution is 1W
and the new direct power data are entered by the horizontal and vertical cursors and ENTER. After
the new power has been set, it will be possible to read the power measurement really present on the
antenna connector (forward and reflected), which may be slightly different from the set one due to
the control circuit error or it may be very different in case of standing waves on the output circuit
which forces the power control circuits to reduce the power in order not to exceed the reflected
power limits.
By means of the horizontal cursor, the power enable can be set, this software command
doesn't
operate
if the transmitter is externally disabled through a CARRIER EN control placed on the rear
IN / OUT connector.
Each output power variation command is softly performed with the achievement of the final value
in 3 seconds approximately.
