Measuring Hpd Br Rx Sensitivity And Rx Ber - Motorola GTR 8000 Manual

GTR 8000 Base Radio
11 Compare the value that displays in the Signal Power field to the base radio Tx Power Out specification that
matches your base station configuration. See
page 1-12.
Be sure to account for cable loss in this comparison.
The output power reference plane is the output connector of the power amplifier. The loss of the transmitter
output cable (PA output to the back of the base radio) is 4% at 700 and 800 MHz. However, the base radio
software allows the transmitter output power to be set at 10% above rated value.
12 Note the value that displays in the Freq. Error field. Tolerance should be +/- 50 Hz.
13 Note the value that displays in the EVM avg field. The value should be less than or equal to 10%.
14 If no further testing is needed, click Change to Normal Mode to return the base radio to normal operation.

5.11.4 Measuring HPD BR Rx Sensitivity and Rx BER

When and where to use:
Follow this procedure to test:
• Rx Sensitivity: Does the 1% Bit Error Rate (BER) meet specifications for your GTR 8000 Base Radio
configuration?
• Rx BER: Does -70 dBm produce a 0.01% Bit Error Rate (BER) or better, as expected?
