the sensor.
7. Calibrate/set-up power meter according to manufacturers instructions.
8. Connect the power sensor at the top of the rack as per diagram
9. Measure O/P power and ensure the level is less than -20dBm
10. Adjust TX Gain for the band of the system under test. Start with the TX gain set to
3300. Adjust the value up or down to obtain a reading as shown in the table below. This is
equivalent to 4 users at 160k. Remember to take into account the value of any attenuation
used to protect the meter.
Band Reading
