2.2.5 Rx Verification
2.2.5.1 Turn off test set generator.
2.2.5.2 Reconfigure the test set to generate a STD 1011 test pattern at -70dBm
level.
2.2.5.3 Verify the Rx LED on the P25netCC channel is lit.
2.2.5.4 Turn off the generator.
2.3 Bit Error Rate Test
2.3.1.1 On PCCT toolbar select Controller Card\Bit Error rate test.
2.3.1.2 Start the generator with a STD 1011 test pattern at -114dBm.( Be certain to
include the insertion loss of the RF cable at the test frequency).
2.3.1.3 Press the Purge Data button and allow the Total Rx Blocks to reach 200
for each generator setting as you decrease the level in 0.5dB increments.
2.3.1.4 The Average Bit Error Rate should be 5% or less for -116dBm (typically -
118dBm .

This completes Radio calibration.
2.4 Load/Save Transceiver Configuration
PCCT has a feature that allows saving the calibration settings for a radio as well as recalling
them. This provides a short-cut around the full calibration procedure in most cases. Sometimes
variation between radios and Channel Cards will require some fine adjustment of the
calibration.
2.4.1 Load/Save Config Window
Open the Configure>Load/Save Config screen and select the transceiver to be loaded (See
Figure 2-15 Load/Save Config Screen).
