DPM Connection
Although unlikely, it is possible to corrupt the power
sensor firmware by connecting it to the DPM while the
DPM is on. To prevent this, always turn the DPM off
before connecting or disconnecting a sensor.
Connect the power sensor to the “Sensor” port on the
DPM using the sensor cable provided. If you are using
the optional PCTool software, connect the PC’s serial
port to the “RS-232” port on the DPM.
RF Connections
Directional Power Sensor (DPS)
Connect the DPS to the RF line so that the arrow on
the DPS points towards the load. The element in the
forward socket should be inserted with its arrow
pointing in the direction of forward power, as shown
below. The reflected element should point in the
direction of reverse power. The forward element’s
power rating must be 10x the reverse element’s rating.
CAUTION
Always turn off the DPM before connecting or
disconnecting a sensor.
WARNING
Never attempt to connect or disconnect RF
equipment from the transmission line while RF
power is being applied.
Leaking RF energy is a potential health hazard.
