RB10 Product Overview

The RapidM RB10 Wideband Bit Error Rate Tester (BERT) is a standalone unit designed for the testing of serial and packet H/V/UHF data modem communications equipment and communications links. The RB10 BERT is used to measure the number of errors (bit or packet) in a data transmission system.

For serial testing the RB10 BERT generates a test data stream that is passed through the data transmission system. The received data stream is compared against a reference data stream to detect any errors introduced by the system under test. The RB10 BERT can detect bits in error and missed bits (also called bit slips).

For packet data and link setup testing the RB10 BERT requests the modem to establish links and send varying packets of data through the transmission system. Indications received from the modem are used to determine link probability as well as packet throughput and packet retry rate.


The RapidM RB10 BERT generates a pseudo-random binary sequence (PRBS) based on standard test patterns. The RB10 generates these data streams at data rates from 50 bps to 120 kbps in synchronous and 50 bps to 230k4 bps in asynchronous DTE modes. The RB10 BERT Is capable of generating and checking user defined patterns from 8 to 128 bits in length. A custom text sequence is also supported.

For serial data testing the 63, 511, and 2047 bit PRBS patterns are standard with continuous and burst transmission modes also supported.

The RB10 BERT has an intuitive graphical user interface on the front panel that displays basic error statistics and allows the user to control the operation of the BERT hardware. The RB10 BERT can also be controlled locally or remotely using the BERT GUI PC S/W which provides more detailed error statistics and test results.
