RF POWER ON
STATUS
Output
Pin
7
is supplied with +15 V
through a 10 k
Ω
resistor. While
RF power is present at the output,
an internal relay opens the
contacts between pin
7
and pin
8
.

With pin
8
grounded externally,
pin
7
will be at +15 V when RF
power is present and at 0 V when
there is
no
RF power.
Note:
For RF to be present at the
output, the output must be
enabled and the set point
level must be above the
minimum specification
