The signal
provided to this analog input represents
a linearly scaled setting for the RF
power set point.
The function of the signal provided to this analog
input depends on the power control mode. In
Forward Power Control Mode, it sets the requested
forward power.
In Load Power Control Mode the requested load
power is set.
In Process Control Mode the requested process
value is set.
The voltage range for this analog input is 0
V to
10
V. 0 V to 10 V correlates to 0 W to nominal
RF
power.
For example, a voltage of 5
V correlates to 50 % of
the nominal RF
power (see type label for actual
rating).

Reflected RF Power
Monitor
AO
The signal on this analog
output provides a linearly
scaled readback of the RF
reflected power.
The range is 0
V to 10 V.
0
V to 10 V correlates to 0 W to nominal RF power.
For example, a voltage of 1
V correlates to 10 % of
the nominal RF
power (see type label for actual
rating).

Isolated Ground
GND
Signal ground connection isolated from chassis
ground. Return pin for DI and DO signals. For
operation, this GND must be grounded either on
host or client side.

When the generator is ready to
deliver RF
power, a 5 V signal is sent to this output.
