COM-1019 DIRECT-SEQUENCE SPREAD-SPECTRUM MODULATOR 20 Mchip/s

$295.00

Direct sequence spread-spectrum (DS-SS) modulator
Programmable chip rates up to 20 Mchip/s
Spreading codes: o Gold sequences (up to 223-1 chips). o Maximal length sequences, (max length 223-1 chips). o Barker codes (length 11, 13). o GPS C/A codes
code modulation: BPSK/QPSK/OQPSK with output spectral shaping filter: raised cosine square root filter with 20%, 25%, 35% or 40% rolloff. Filter can be bypassed
Internal generation of pseudo-random bit stream and unmodulated carrier for test purposes
Built-in channel impairments generation: - additive white Gaussian noise - frequency offset (Doppler)
Connectorized 3”x 3” module for ease of prototyping. Standard 40 pin 2mm dual row connectors (left, right). Single 5V supply with reverse voltage and overvoltage protection. Interfaces with 3.3V LVTTL logic
