Directional Power Sensor (DPS)
Setting Scale
Note: The Bird DPS uses Bird Plug-In Elements. These are labeled
with a max power and a frequency range.
Note: The transmitter frequency should be within the
element range.
Note: Forward and Reflected full scale power must be entered
manually.
1. Press Scale.
2. Select the power units (W, mW or kW) with up and down arrow keys.
3. Enter the maximum power of the element in the forward element socket
using the numeric keypad and <.> key.
Note: The element’s max power is listed on the element nameplate.
4. Press OK.
Terminating Power Sensor (TPS)
Zeroing Sensor
Over time, the sensor’s “zero value” (reading with no applied RF power) can
drift due to environmental factors (temperature, humidity, etc.) This can make
the readings performed by this sensor less accurate by the drift value. If the drift
would be a significant error, re zero the sensor.
1.
Ensure the sensor has been connected to the DPM.
2. Press and hold “0” for two seconds to begin zero calibration.
Note: “Zero/Cal” will be displayed and calibration will begin.
WARNING
RF voltage may be present in RF element socket. Keep element in socket
during operation.
CAUTION
Do not exceed 2 W average or 125 W peak power for 5 μs when using the TPS
or the TPS-EF. Doing so will render the sensor inoperative.
