V11. RF Power Test Description A TRUE COPY CERTIFICATION ON LAST PAGE RYAN L. BUTLER, CLERK The purpose of the TX power test is to verify the accuracy of the configured power level as set in the RFU Settings field of the EM2 software. EM2 setting is a displayed setting of TX RF Power output at the flange at the top of the stack with a calibrated power meter. Both Outdoor and Indoor RF are checked at the final connection point before the flex waveguide connection for power levels. Note: For Proteus MX+/MXD terminal the power output is software configurable not hardware set. There is no "fine tune" adjustment. You set the desired output power using the EM2 software. The Terminal output power is set per the PCN requirements. Instructions 1. Log on to the Terminal under test if you have not already logged on. a. Connect a PC with the EM2 software installed via the serial connector on the front of the terminal labeled "COMPUTER". b. Open the EM2 software and on the initial log -in screen select "Serial" from the pull down and choose the appropriate "COM PORT" that the PC is using. c. Enter the username: "admin" (note this cannot be changed) enter the password. The default password is "password" which can be changed). Once the correct "admin" and "User password" is entered you will be "logged on" and the displayed terminal icons will go from gray to blue to indicate communication with the terminal under test. 2. In the EM2 software go to the "Test" and "RFU Mute" selection and MUTE all the RF portions of the terminal under test. (Factory location only). Set the time to be "0" so it does not UN -Mute. Warning — In the field DO NOT Mute the Far End terminal unless you set a time out. You will lose communication to that terminal which can only be un -muted by logging on locally. 3. Remove the path cabling from the RF unit under test and connect the Power Meter to the transition. Warning: Do not to exceed the power rating of the Power Sensor. Use a "high power" sensor capable of + 33 dBm. 4. Turn off ATPC and read max power out of each radio based on the radios total power capability. 5. In the EM2 software, go back to the "Test" and "RFU Mute" screen and set the transmitter connected to the power meter to "On Line". Measure the power (See current PCN for power settings of each radio) and record in the "Measured Power Output' Section of the Terminal Acceptance form. 6. Go back to the RFU Settings and Mute the RFU. 7. Disconnect the Power meter from the flange and re -connect cabling to the flange disconnected in step 3. 8. Un -Mute all RF units. 9. Ensure that the "On Line" switch is set to "Auto" on the Switching Shelf for protected terminals. Page 19 of
