General Description:
The PSM-500L uses Datum Systems’ proprietary techniques of direct modulation and demodulation to completely eliminate transmit and receive IF sections and their associated filters. Sophisticated digital signal processing eliminates all on board physical adjustments and provides performance within 0.3 dB of theoretical. Direct Digital Synthesis (DDS) of the transmit, receive and data rate synthesizers allow settings to 1 Hz and 1 bps respectively.

The L-Band PSM-500L is optimized for low cost, high performance VSATs and small stations, while the companion PSM500S, 70MHz IF version is ideal for hub station. The PSM-500L series adds 8PSK, 16QAM, Reed-Solomon and a built-in multiplexer to the PSM-4900 series. The PSM-500L series is unmatched by any other modem in its class for fast acquisition, BER performance and power/band width optimization. It uses dedicated DSP for extremely fast acquisition over a programmable range. The PSM-500L is available in 3 upgradable versions, the PSM-505L, PSM-511L and PSM-523L offering the latest modulation, coding and FEC technology plus data rates to precisely meet your needs. The transmit and receive can independently use BPSK, QPSK, OQPSK, 8PSK and 16QAM modulation at any data rate or configuration settings. Reed-Solomon, IBS multiplexer, AUPC and remote modem control channels are built-in. Sophisticated TPC and other FEC options are available. The full front panel provides a backlit LCD display, full keypad and LED indicators for monitor and control of all modem parameters.
