Bit Error Rate Testers (BERT) — Equipment & Solutions

BER is measured by counting the number of erroneous bits received versus the total bits transmitted over a defined period. A BERT instrument injects a known pattern, monitors the output, and calculates the ratio. Lumistar's LS-68 Series integrates BER reading directly into its digital processing engine alongside real-time telemetry display for immediate analysis.

BER testing verifies the integrity and performance of digital communication links by quantifying transmission errors. In aerospace and flight test applications, it ensures telemetry data received from airborne platforms is reliable and accurate. It helps engineers identify signal degradation, RF link issues, or equipment faults before and during critical flight test operations.

BER is calculated by dividing the number of bit errors detected by the total number of bits transmitted: BER = (Number of Error Bits) / (Total Bits Transmitted). For example, 10 errors in 1,000,000 transmitted bits yields a BER of 1×10⁻⁵. Integrated BERT equipment like the LS-68 Series performs this calculation automatically and displays results in real time.

Lumistar's LS-68 Series is available in three configurations: a small modular format for compact deployments, a portable lunchbox (LS-68-M-P1) for field use, and a 1U rack-mounted unit (LS-68-R1) for fixed facility installations. All configurations support integrated BER reading, bit sync, frame sync, and full telemetry decommutation.

Yes. The LS-68 Series includes PCM data simulation capability, allowing engineers to generate and inject known PCM patterns for end-to-end telemetry system verification. This is particularly useful for pre-flight testing, ground station validation, and debugging telemetry links without requiring an active airborne transmitter.

Yes. The LS-68 Series supports Telemetry over IP (TMoIP), enabling processed telemetry data to be distributed across IP networks to remote workstations or facilities. It also includes an integrated IRIG Time Code Reader/Generator and PTP Network Time synchronization to ensure precise time-stamping across distributed data acquisition and monitoring systems.
