5 18 SET POINT Analog
input
This signal sets the RF output
set point. Depending on the
regulation mode, the set point
refers to forward power
(P
forward
), load power (P
real
),
or external power (DC Bias).
The default range is 0 V to
10 V, but you can change this
range (see
“Analog Inputs” on
page 4-20 ).
A 0 V to 10 V signal applied to
this pin linearly controls the
set point of the CESAR
generator:
Default setting: 0 V to 10 V =
0 W to 1.2 kW
For DC bias regulation, the
scaling of the set point must
be the same as for the DC
bias signal (see pin 7).
For a wiring diagram, see
Figure 4-12 on page 4-23 .
6 19 RF FORWARD
POWER/
DC BIAS
REGULATION Digital
input
Use this signal to select DC
bias or RF power regulation
mode. To regulate on DC bias
input, apply a positive voltage
of 4 V to 30 V to this pin. To
regulate on forward or load
power, apply a voltage of 1.5
V or less or an open
connection.
See pin 8 for switching
between forward and load
power regulation.
For a wiring diagram, see
Figure 4-13 on page 4-24 .
