• Measure RX Signal Strength. (This can be done by initially leaving the antenna connected to the radio,
performing a 60 second carrier test on the remote RTU using Toolbox Utilities, Carrier Test; powering
down the local RTU and then connecting the antenna to the test-set as shown above). Ensure that the
antenna is pointing in the right direction by using a compass bearing or by using line of sight. Adjust the
direction and height of the antenna to get the best signal strength.
• Connect the radio test-set and watt meter as shown below.

• Perform a carrier test on the local RTU by using Toolbox.
• Measure forward and reverse power. There should not be any reverse power. Forward power is typically
1 to 5 watts.
• Measure Frequency Deviation and Error. There should be a frequency deviation of 3kHz for wideband
radios and 2kHz for narrowband radios. The Frequency Error should be between -1kHz and +1kHz.
• (Optional) Connect the radio test-set and watt meter as shown below.
Caution! Do not connect the radio cable to the antenna input on the radio test set. Note the
transmit power level when the carrier detect LED on the RTU turns ON and OFF.
