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
1.9 GTR 8000 Base Radio/GPW 8000 Receiver Specifications,
.
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%.

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?
Procedure Steps
