Making and Checking RF Settings (UHF)
Checking with Wireless Studio
The RF level meter of the Wireless Studio application can be used to verify the RF level.
RF level meter
1 Power down all transmitters.
2 Determine the channel plan for the receiver.
Select the band
Select the band based on your intended purpose and your wireless environment (e.g., whether TV
broadcast transmissions exist).
* The band is fixed for the DWR-S01D.
Take factors such as effective use of frequencies and the risk of mutual interference with other wireless
equipment and/or analog wireless systems into consideration.
Select the group
There are groups that are designed for simultaneous multi-channel operation and others that are not.
Select an appropriate group according to the intended purpose and the number of channels to be
operated simultaneously.
Groups not specifically designed for simultaneous multi-channel operation are 00 for US models, 00 for
EU models, and groups that include TV channel names (e.g., TV62). In order to accommodate flexible
channel planning even when using these groups, continuous channel setting is possible in 125-kHz steps
(25-K steps for groups that include TV channel names on EU models). When using these, design your own
channel plans according to specific requirements.
3 Check for external interference.
Sample settings for checking
Band to use: To be established in this step.
Group to use: To be established in this step.
Antenna installation location/orientation: Install according to requirements described in “Antenna
installation position” (page 43).
Antenna gain: Set according to instructions in “Booster gain setting conditions” (page 44), ensuring that
cable losses can be fully covered.
Number of antennas: Determine according to requirements described in “Antenna installation position”
(page 43).
TX RF power: TX to be OFF in this step.
RX attenuator: Provisionally set to 0 dB.
Checking procedure
Check the RF level meter indication. Verify that interference is less than 10 dBμ (RF level meter is always out.).
Check possible sources of interference including TV broadcast signals and external interference noise and
determine the band and group to use.
