Description
Pin 7 is supplied with +15 V
through a 10 kΩ resistor. While
RF power is present at the output,
an internal relay opens the
contacts between pin 7 and pin 8.
(See Figure 4-6 on page 4-9
electrical diagram.)
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
(see "Electrical
specifications" on
page 3-5).
Floating pin that can be used as a
reference for pin 7; while RF
power is present at the output, an
internal relay opens the contacts
between pin 7 and pin 8.
Enables output RF power with an
external contact closure between
pins 4 and 9; this pin is tied to the
LED anode of an opto-coupler
through a 1 kΩ resistor.
(See Figure 4-4 on page 4-8
an electrical diagram.)
