BERT Testing
Setting Up a PHS Bit Error Rate Test
Selecting the BERT Data Pattern and Total Bits
1. Press Aux Fctn > BERT > Baseband BERT > Configure BERT.
Ensure that the
Data softkey shows PN9 as the selected data pattern. If this is not the case,
press
Data > PN9.
2. Press Total Bits > 100000 > Bits.
Selecting the BERT Trigger
1. Press Return > Configure Trigger.
Notice that the Trigger Key is active in the BERT Trigger softkey as the default setting.
2. Press
Return > BERT Off On.
Starting BERT measurements
Press the front panel Trigger hardkey to start the BER measurement. You will see the
measurement result values of the Total Bits, Error Bits, and BER on the signal generator
display.
NOTE If you encounter problems making a BER measurement, check the following:
• Make sure that the cable connections are properly configured.
• Make sure that the data pattern for the BER measurement, specified by the
Data softkey, matches the data pattern in the traffic channel (TCH) for the
RF signal being input to the radio under test.
• Make sure that the RF is turned on.
• Make sure that the amplitude is set to the correct level.
• Make sure that the radio under test is controlled to receive the signal of the
specified carrier frequency and the timeslot.
