2. Press the DOWN button (item 2) or the UP button (item 3) until line 3 of the display
shows the current control source (PANEL CONTROL, ANALOG CONTROL, or
SERIAL CONTROL).
3. Press the VALUE UP button (item 5) or the VALUE DOWN button (item 6) until
ANALOG CONTROL is displayed on line 3.
4. Press the ENT button (item 5) to save the selection.
5. Press the RUN button (item 1) to return to exit the programming menu.
SERIAL control:
To change the control source to the Serial interface connector,
1. Press the PGM button (Item 1) once.
2. Press the DOWN button (item 2) or the UP button (item 3) until line 3 of the display
shows the current control source (PANEL CONTROL, ANALOG CONTROL, or
SERIAL CONTROL).
3. Press the VALUE UP button (item 5) or the VALUE DOWN button (item 6) until
SERIAL CONTROL is displayed on line 3.
4. Press the ENT button (item 5) to save the selection.
5. Press the RUN button (item 1) to return to exit the programming menu.
Note: Pressing the RUN button (item 1) automatically saves the current setting and

programming menu.
Note: The control source and control mode selection is saved when the R301 RF Power
Supply is powered down – it will power-up in the same mode.
Leveling Mode:
The leveling mode is the method the R301 uses to regulate its output power. There are three
(3) leveling mode selections.
· The “PWR” (power) leveling mode uses the R301’s internal power sensor to regulate the
RF output power. There are two types of power leveling available on the R301 RF
Power Supply:
1. Forward (FWD) Power leveling: The forward output power is measured by the
R301’s internal power sensor and compared against the requested output power
(power setpoint). The R301’s power amplifier increases or decreases its output to
maintain the requested power setpoint. Reflected power is displayed and
monitored for internal protection.
2. Load Power Leveling: The forward and reflected power is measured by the
R301’s internal power sensor. The reflected power signal is subtracted from the
forward power signal and compared against the requested net power (power
setpoint) to be delivered to the load. The R301’s power amplifier output increases
or decreases its output to maintain the net power delivered to the load. Reflected
power is displayed and monitored for internal protection.
