Digital Television Signal Analyzer Measurement Guide : ISDB‑T Signal Analyzer : BER Measurements Setup, Custom (Option 79)
 
BER Measurements Setup, Custom (Option 79)
Measurement of BER is a useful tool for evaluating the quality of a broadcast signal. This option requires that additional hardware be installed in the instrument in order to perform Bit Error Rate (BER) measurements on ISDB‑T broadcast signals. Bit Error Rate (BER), Packet Error Rate (PER), TMCC, and MPEG TS Bit Rate can be measured simultaneously.
ASI Out Connector
The digital signal output, 50 ohm Type‑N female connector (shown in Figure: Instrument Connectors for Digital Television Signal Analysis) is present only when both ISDB‑T (Option 30 and ISDB‑T BER (Option 79) are installed on your instrument.
The ASI function produces MPEG TS data output during a BER measurement. This output can be connected to MPEG TS analysis equipment to monitor video errors, or it can be connected via an appropriate ASI‑to‑USB demultiplexing and decoding accessory for channel identification and monitoring purposes.
