SpreadSpectrum PN Code Generators

New Wave Instruments currently offers a line of three PN code generators expressly designed for spread spectrum development. The LRS-100 is a convenient 16-stage desktop generator, and the LRS-205 and LRS-220 are 32-stage rack-mount generators with GPIB capability. All three provide pseudo-random sequence outputs at baseband, and include both TTL outputs and AC outputs for directly driving double-balanced modulators and mixers.

Note: If you found this page through a search engine, you may have misspelled "spread spectrum" as one word (spreadspectrum). To view the most recent version of this page (with proper spelling), click here.

These generators will complement your lab's RF spectrum analyzer and signal generator perfectly. Brief descriptions of the generators are given below, and a handy Feature Comparison table is available.

LRS-100 SpreadSpectrum Generator

Price:   $11,000 (Domestic)
Delivery:   From stock to 30 days

The LRS-100 generates PN codes that are useful for developing and testing both spreadspectrum (spread spectrum) and conventional data communication systems. These sequences are generated with a configurable 16-stage linear-feedback shift register.

The register size, feedback taps, initial register contents (initial fill), and length of the linear recursive sequence (LRS) are all fully programmable. Different modes of operation include BPSK, QPSK, OQPSK (SQPSK), GOLD/JPL (R8 max), and Burst Mode for radar applications, with a maximum shift rate of 25 MHz.

A built-in clock and data simulator are included for the user's convenience, or external sources can be selected. External inputs include clock, preset, start/stop, and data. External outputs include a buffered clock, I and Q direct sequences, sequence-repeat (epoch) strobes, and a parallel interface for driving a frequency hopper. In addition, I/O ports are provided for conveniently connecting a pair of LRS-100s together in a master/slave configuration for maintaining synchronization between the two. This feature is particularly useful for transmitter/receiver applications.

LRS-205 SpreadSpectrum Generator

Base Price:   $16,000 (Domestic)
Delivery:   From stock to 30 days

The LRS-205 generates PN codes that are useful for developing and testing both spreadspectrum (spread spectrum) and conventional data communication systems. These sequences are generated with a configurable 32-stage linear-feedback shift register.

The register size, feedback taps, initial register contents (initial fill), and length of the linear recursive sequences (LRS) can all be set manually via a soft menu on the display, or automatically via an optional GPIB interface. Different modes of operation include BPSK, QPSK, OQPSK (SQPSK), and Burst Mode for radar applications, with a maximum shift rate of 25 MHz. Custom configurations are available upon request.

External inputs include clock, preset, start/stop, and data. External outputs include a buffered clock, I and Q direct sequences, a sequence-repeat (epoch) strobe, and a parallel interface for driving a frequency hopper. In addition, I/O ports are provided for conveniently connecting a pair of LRS-205s together in a master/slave configuration for maintaining synchronization between the two. This feature is particularly useful for transmitter/receiver applications.

LRS-220 SpreadSpectrum Generator

Base Price:   $22,000 (Domestic)
Delivery:   From stock to 30 days

The LRS-220 includes all the functionality of the LRS-205, but is equipped with two sequence generators, thus enabling it to generate Gold, JPL and syncopated codes.

The LRS-220 generates PN codes that are useful for developing and testing both spreadspectrum (spread spectrum) and conventional data communication systems. These sequences are generated with configurable 32-stage linear-feedback shift registers.

The register size, feedback taps, initial register contents (initial fill), and length of the linear recursive sequences (LRS) can all be set manually via a soft menu on the display, or automatically via an optional GPIB interface. Different modes of operation include BPSK, QPSK, OQPSK (SQPSK), GOLD/JPL, and Burst Mode for radar applications, with a maximum shift rate of 25 MHz. Custom configurations are available upon request.
