CDMA - DSSS Trainer with BER Measurement Manufacturer,Supplier and Exporter in India
Product Code : SCL-CE-12556
Indian Lab Suppliers supplies the CDMA - DSSS Trainer with BER Measurement (Product ID: 12556), part of the Communication Equipment range under Laboratory equipment, a Bit Error Rate (BER) measurement module for CDMA-DSSS systems, comparing a received bit stream against a locally generated PRBS-11 reference sequence and displaying key internal signals in real time via ComScope software on a host computer.
Note on naming: this board's name is very close to our CDMA - DSSS Trainer (Product ID 12555), so please confirm the exact model with our team. The source material available to us for this listing describes its BER-measurement circuitry and instrumentation in detail but does not itemize its own spreading-code, chip-rate or baseband-modulator specifications; if you need those figures, please confirm them with our team before ordering. For a closely related instrument-grade CDMA-DSSS platform with onboard BER measurement, see also our Understanding CDMA-DSSS Communication System with BER Measurement (Product ID 12519).
Quick Answer
This module measures bit error rate by comparing a received bit stream against a locally generated replica of a 2047-bit, 11-tap-LFSR PRBS-11 reference sequence, with an adjustable measurement window, automatic synchronization, cycle-slip detection and a 32-bit cumulative error counter, and lets students view key internal signals in real time on a host computer via ComScope software.
Key Features
Measures actual bit errors while a known PRBS-11 pseudorandom test sequence is transmitted · accurate BER measurement down to 10-8 · adjustable measurement window from 1,000 bits to 1,000,000,000 bits, trading off BER range against measurement duration · fast automatic synchronization · cycle-slip detection · 32-bit cumulative BER counter for long-duration measurements · 1-bit serial / 2-bit parallel input selection (I before Q, or I/Q) · ComScope software for real-time capture and display of key internal signals on a host computer.
