Signal generator LSX2091D

microwaveRFsingle-channel

Overview
The Lucid-X is a small-footprint modular microwave signal generator available in multiple form factors (Desktop, PXIe module, benchtop, rackmount, portable). Designed for low phase noise and high spectral purity, the Lucid-X family supports modulation, fast coherent frequency switching and flexible interfaces for system integration.

Key features

• Fast switching speed <10 μs (ultra-fast switching option)
• Coherent frequency switching
• AM, FM, PM, Sweep & Pulse Modulation
• Phase noise example: -148 dBc/Hz @100 MHz (10 kHz offset), -133 dBc/Hz @1 GHz, -114 dBc/Hz @10 GHz
• LAN, USB, and SPI integrated interfaces

Signal integrity and purity
The Lucid-X family provides exceptionally low phase noise across microwave frequencies and is suited for applications requiring high signal purity such as local oscillators, intermodulation distortion measurements and high-performance DAC/ADC clocking. Typical spectral performance includes harmonics ~ -50 dBc and non-harmonics ~ -90 dBc.

Analog and pulse modulation
The instrument supports built-in analog modulation including AM, FM, PM and Sweep. Typical modulation capabilities: FM maximum deviation up to 10 MHz and rates up to 1 MHz; AM linear depth up to 90% and rates up to 100 kHz; PM peak deviation up to 360°; Pulse modulation with high on/off ratio (typ. ~70 dB) and rise/fall times <15 ns. Pattern and pulse modulation modes enable realistic radar, EW and communication signal simulation.

Fast frequency switching
Ultra-fast switching (10 μs option) reduces dead time in automated test and allows simulation of frequency-hopping and pulse-to-pulse scenarios (e.g., frequency-hopping radars, secure radios). Fast coherent switching improves throughput in manufacturing and enables advanced test sequences without sacrificing accuracy.

Control and programming
Supports industry-standard SCPI/VISA commands and remote control via LAN or USB. Integration is straightforward using Python, MATLAB, C#/C++ or NI tools (LabVIEW). A virtual front panel is provided for local or networked GUI control.

Applications

• Radar STALO / LO sources
