LS-28-SRSM Advanced Technology Modular Single-Channel Receiver & Telemetry Processing System Data Sheet

PublishTime：2024-12-12

●The Lumistar LS-28-SRSM Modular Single-Channel Receiver offers a small profile low-cost high-performance multi-band multi-mode COTS solution for a modern Telemetry Receiving System applications. The unit functions as an independent single-channel data & tracking receiver in one package.
●The LS-28-SRSM is an advanced-technology Single-Channel Receiver employing sophisticated Lumistar “fifth generation” Digital Signal Processing (DSP) technologies. The LS-28-SRSM supports RF telemetry reception of up to six RF bands including E, S, Lower-L, Upper-L, P, C, (as well as customer defined bands from 200 MHz to 7 GHz). The RF input signal is converted to a fixed 70 MHz intermediate frequency (IF). The IF signal is then digitized by a high performance sowtware defined digital IF receiver. The unit has provisions for direct PCM bit-synchonization from external baseband sources as well from the RF channel data. 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. In addition to the digital FM demodulation, traditional analog single-symbol FM demodulation is included as an option. PCM code converted bit sync output data is provided simultaneously to TTL and high speed differential (RS422/485 signal standards). Optional IRIG UDP time stamped data, frame sync, or decom outputs 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 very powerful “onboard 70 MHz signal modulator” are included at no additional cost. The LS-28-SRSM is compatible with any Operating Systems and is controlled and statused either serially (USB or 232) or via Ethernet. 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 up to 128GB of demodualted data (minor frame time stamped). The unit is powered from a single DC power supply from +9V to +42V, consuming under 45 watts of power.
●Unlike analog legacy receivers, the LS-28-SRSM is a true software-defined radio whose digital implementation is highly flexible and expandable. The IF receiver functionality is realized using an architecture employing five 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 50 Mbps for QPSK/OQPSKSQPSK/SOQPSK/Mutli-H CPM. The LS-28-SRSM sensitivity and adjacent channel interference performance is superior due to the use of hardware IF “SAW” and DSP “FIR” filtering method. 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-SRSM 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.
