Measuring Loopback Bit Error Ratio
1. Configure the mobile station to generate a 12.2 kbps or 64 kbps reference measurement channel (RMC).
2. Press the
Measurement selection
3. Select the Loopback BER measurement.
4. Press the Bit Error Setup (
5. Set the measurement parameters as needed for your measurement situation.
To see how low levels of cell power into the mobile affect the bit error ratio, press Cell Power (
reduce the level. With the level into the UE set to -106.70 dBm/3.84 MHz, the example above indicates a failed
BER value (the 3GPP standard specifies a BER of no more than 0.1% at this input level).

Observe how reducing the cell power
to low levels causes the bit error
ratio to increase.
