Measurement Parameters FER Measurement Results Input Signal Requirements Key TIA/EIA-98-E Tests Using FER How is an FER measurement made? Frame Error Rate (FER) measurement is used to test frame error rate vs bit error rate the performance of a mobile station's receiver. FER measurements can only be made relation between bit error rate and snr on the forward traffic channel (F-Traffic) for IS-95 system or forward fundamental channel (F-FCH) for IS-2000 system and frame error rate definition a call must be connected with a loopback service option (such as SO2, SO9, SO55 or SO75). The forward supplemental channel (F-SCH) for IS-2000 system is measured using TDSO FER measurement bit error rate calculation (see TDSO Frame Error Rate Measurement Description ). During an FER measurement, the test set sends a sequence of frames to the mobile station. Each frame contains CRC (Cyclic Redundancy Code) bits, which provide frame quality indicator and allow the mobile station to verify that it has correctly decoded a frame. The mobile station is put into a loopback service option

and makes its best attempt to decode each received frame sent from the test set. Once the mobile station determines the CAT_TYPE that specifies whether the frame received is a good frame, bad frame, frame erasure, or a frame blanked by signaling, the mobile station encodes and re-transmits the frame, with the first two bits replaced with the CAT_TYPE information, back to the test set. The test set compares each received frame to the corresponding frame that was sent and validates the CAT_TYPE information, then determines the measurement results (see FER Measurement Results ). The test set keeps a running count of the measured frames and the number of frames that contain bit errors. Intermediate measurement results are periodically available on the front panel display, but are not available programmatically through the GPIB interface. Confidence Level Testing Confidence level testing is a feature of FER measurements that applies statistical analysis to FER measurements so that pass/fail test results can be obtained in the shortest possible time. When confidence level is on, a minimum number of frames as specified must be measured before conf

Is there a conversion or something between them? I think when it comes to the probability, it is always between 0 and 1, but error rate might drop to 10e-5. 1st November 2006,12:09 2nd November 2006,05:05 #4 rsrinivas Advanced Member level 1 Join Date Oct 2006 Location bengalooru Posts 415 Helped 50 / 50 Points 4,038 Level 14 BER and bit error probability The thing wat u told is also between 0 and 1. 0.00001. 2nd November 2006,05:44 #5 samasimo Junior Member level 3 Join Date Nov 2006 Posts 31 Helped 11 / 11 Points 1,547 Level 8 BER and bit error probability BER is the number of errorounous bits/total number of bits BEP is the probability that a certain bit will be recieved with error For a large number of transmitted bits(typical assumption),both of them are equal and the 2 terms are usually used interchangebly in the literature but BER is more common + Post New Thread Please login « ISO/IEC standard 13818-1 2000 | Lecture Slides 4....

In some systems, FER is referred to as PER (packet error rate) or BLER (block error rate). The input signals to the reference (ref) and test (test) inputs must be bit streams. The bit streams must be synchronized, otherwise the BER/FER estimates are wrong. The Start parameter defines when data processing starts. The end of data processing depends on the settings of the parameters ControlSimulation, Stop, and EstRelVariance: If ControlSimulation is NO, then Stop and EstRelVariance are ignored. Data processing ends when the simulation ends. In this case, the end of the simulation is determined by other sink or source components that control the simulation. If ControlSimulation is YES and EstRelVariance is 0.0, then data processing ends when Stop is reached. If ControlSimulation is YES and EstRelVariance is greater than 0.0, then data processi
