ENABLE
Digital
input
RF output is enabled when a 4 to
30 V input (pin 9, RF ON BIAS,
can be used as a voltage source)
is present on this pin.
Note: The interlocks must be
satisfied and the setpoint
must be within the Output
power range before unit
will deliver power. See
Table 3-3. on page 3-6 for
the Output power range
specification.

FORWARD/LOAD
POWER SETPOINT
Analog
input
This analog signal provides a
linearly scaled control of the
forward or load output power
depending on the regulation
mode (1 V per 1 kW output
power).
Note: The interlocks must be
satisfied and the setpoint
must be within the Output
power range before unit
will deliver power. See
Table 3-3. on page 3-6 for
the Output power range
specification.
