Test Specifications
1 RX Ref Sensitivity Type Ib BER
1 RX Ref Sensitivity Type Ib BER
Description This specification sets the upper limit for residual type Ib BER (Bit
Errors) on a full-rate speech traffic channel (TCH/FS). If this upper
limit is exceeded, an “F” (for fail) will be displayed next to the RX BET
for RES Ib measurement result.
Default value The default value for the GSM900 Upper Limit is 0.41 (%).
The default value for the DCS1800 Upper Limit is 0.41 (%).
The default value for the PCS1900 Upper Limit is 0.40 (%).
NOTE Parameter 22, (RX BER/FER results) sets the units for this
specification (percent, ppm, or count).
Example If you want your test procedure to report a failure if the number of
residual Type Ib bit errors exceeds 82000, enter 0 in the lower-limit
column and 82000 in the upper-limit column. Next, set parameter RX
BER/FER Results to 0 to have results displayed in bit error count.
