LS-28-DRSM Advanced 4th Gen Technology Modular Dual-Channel Receiver/Combiner Telemetry Recording & Processing System with UDP Data Broadcast Data Sheet

PublishTime：2024-12-12

●The Lumistar LS-28-DRSM Modular Dual-Channel Receiver/Combiner Recording and Telemetry Processing System offers a small profile low-cost high-performance multi-band multi-mode COTS solution for a full up modern Telemetry Receiving System application. The unit functions as an independent data & tracking receiver/recorder/data processor in one small package.
●The LS-28-DRSM is an advanced technology Dual-Channel Receiver/Combiner employing the most current sophisticated Digital Signal Processing (DSP) technologies. The LS-28- DRSM supports independent two-channel reception and/or combining of up to six RF bands including E, S, Lower-L, Upper-L, P, C, (as well as customer defined bands from 250 MHz to 7 GHz). Each RF input is converted to a fixed 70 MHz intermediate frequency (IF). These IF signals are then digitized by a two-channel digital receiver. The IF receiver provides diversity combining as well as 2-channel independent mode operation. The system has a provision for direct PCM bit- synchonization from external sources as well for Combined or Independent channel data from RF or IF. Digital multi-mode demodulation options include Multi-Symbol PCM/FM, SOQPSK, BPSK, QPSK, OQPSK, SQPSK, AQPSK, AUQPSK, PCM/PM, and Multi-H CPM. Sub-carrier(s) demodulation can also be provided, other formats available upon request.
●In addition to the digital FM demodulation, traditional analog single-symbol FM demodulation is included. PCM code converted output data is provided simultaneously to both TTL and high speed differential (RS422/485 signal standards). Optional IRIG Chapter10 UDP time stamped data packet outputs in throughput mode are available. Other formats are available. Standard user features such as O-scope Eye Pattern and Constellation diagram displays, IF spectral displays at 70 MHz, Bit Error Rate Reader and a Data Modulator are included at no additional cost. The LS-28-DRSM is compatible with any Operating System and is controlled and statused either serially (USB or 232) or via a GigaBit Ethernet connection. All Ethernet receiver command and status controls are TCP, and the resulting user displays and data streaming is via UDP ethernet. The unit has the ability to optionally record 32 GB of demodualted data (minor frame time stamped) for each channel (CH1/CH2/Combined). The unit is powered from a single DC power supply from +9V to +42V, consuming approximately 45 W.
●Unlike analog legacy receivers, the LS-28-DRSM is a true software-defined radio whose digital implementation is highly flexible and expandable. The IF receiver/combiner functionality is realized using an architecture employing state-of-the-art digital processing engines, which can operate as a single or dual channel receiver/combiner. The IF receiver processes data rates from 1 kbps to 30 Mbps for MS- PCM/FM, 1 Kbps to 30 Mbps for BPSK & PCM/PM, and up to 60 Mbps for QPSK / OQPSK / AQPSK / SOQPSK / Mutli-H CPM. The LS-28-DRSM sensitivity and adjacent channel interference performance is superior due to the use of combining hardware IF “SAW” and DSP “FIR” filtering methods. By using this method, IF bandwidths are optimaly set by software “as a function of data rate/PCM code/modulation format”, but can be overridden by the user if required. For multi-path avoidance scenarios, the digital combiner operates at fade margin “break frequencies” up to 50 KHz. Best source selection/combining can also be performed via software.
●The performance of the LS-28-DRSM is repeatable, day-after-day, year-after-year, from unit-to-unit. It requires no periodic calibration. Life cycle costs are greatly reduced because future upgrades (such as new modulation formats) or an improved DSP algorithm are all implemented via software and/or firmware via an on-site upgrade.
