Signal generator LSX1494B

microwaveRFsingle-channel

Overview
The Lucid-X (LSX) family is a compact, modular microwave signal generator platform engineered for low phase noise, coherent frequency switching and flexible form factors. The LSX1494B is the 14 GHz, four‑channel benchtop configuration, suitable for laboratory and test‑cell applications where multi‑channel coherent sources and advanced modulation are required.

Key features

• Modular, small‑footprint architecture available in Desktop, PXIe, Benchtop, Rackmount and Portable form factors
• Fast switching: ultra‑fast options down to 10 μs; fast option 100 μs
• Coherent frequency switching for phase‑stable multi‑channel operation
• Analog modulation: AM, FM, PM, sweep and pulse modulation
• High spectral purity with low phase noise
• Standard interfaces: LAN, USB and SPI

Performance highlights

• Phase noise examples (Lucid‑X family): -148 dBc/Hz @ 100 MHz, -133 dBc/Hz @ 1 GHz, -114 dBc/Hz @ 10 GHz (10 kHz offset)
• Harmonics typically ≤ -50 dBc; spurious non‑harmonics ≤ -90 dBc
• Pulse modulation: ON/OFF ratio ≈ 70 dB; rise/fall times < 15 ns
• FM: deviations up to 10 MHz, rates up to 1 MHz
• AM: linear depth up to 90%, rates up to 100 kHz
• PM: peak deviation up to 360°

Modulation & switching
The LSX family supports versatile analog modulation (AM, FM, PM, sweep) plus advanced pulse and pattern modulation. Fast, coherent frequency switching enables realistic simulation of frequency‑hopping and pulse‑to‑pulse scenarios for radar, electronic warfare and secure communications. Optional ultra‑fast switching (10 μs) available for time‑critical applications.

Control & Programming

• Standard SCPI command set and VISA for remote control
• Supported environments: Python, MATLAB, C#/C++, LabVIEW
• Virtual front panel for local or remote graphical operation
