TEST REPORT

8 Frequency Stability
Test result: Tested

8.1 Limit
The frequency stability shall be sufficient to ensure that the fundamental emissions stay within the
authorized bands of operation.

8.2 Measurement Procedure
Temperature Variation
The EUT was tested over the temperature range -30°C to +50°C in 10°C steps with -48 VDC Power
Supply. At each temperature step, the Base Station was configured to transmit at maximum power on
the middle channel of the operating band.

Voltage Variation
The EUT was tested at the supplied voltages varied from 85 to 115 percent of the nominal values of -48
VDC. At +20°C, the Base Station was configured to transmit at maximum power on the middle channel
of the frequency block.
