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.
