Pin Name Type Description
11 Leveling select DI Ground referenced logic input. (See Note 2)
LOW - Selects forward-power leveling.
HIGH - Selects an alternative power-leveling
mode.
Leaving this pin disconnected will ensure a
configurable HIGH or LOW state.
Note: The alternate power-leveling mode is
selected via a software switch in a
CALIBRATION menu. Either load-power
leveling or an external source such as DC
Bias may be selected. The default is Load
Power Leveling.
12 Load power (+) AO A linear DC voltage that represents the load
power output level.
0 V = 0 W and the max. value is adjustable
between 0 and 12 VDC. Typically calibrated
to 10 VDC = Maximum Rated Power.
13 +15 VDC User voltage for interface purposes. Rated
10 mA max.
14 Max. power (C) DO Collector side of isolated transistor switch
for Pin 1.
15 Reflected power
return (-)
AO Signal return for Pin 2.
16 Forward power
return (-)
AO Signal return for Pin 3.
17 RF ON/OFF
Control (-)
DI Signal return for Pin 4.
18 Power set point
return (-)
AI Signal return for Pin 5.
19
GND Signal / Chassis ground.
20 RF ON (C) DO Collector side of isolated transistor switch
for Pin 7.
21 GND Signal / Chassis ground.
