Signal generator LSX2092B

microwaveRFdual-channel

Overview
The Lucid-X is a small-footprint modular microwave signal generator available in multiple form factors (Desktop, PXIe module, Benchtop, Rackmount, and Portable). Designed for low phase noise and high signal purity, the family covers frequencies up to 40 GHz; the LSX2092B is the 20 GHz dual-channel benchtop configuration.

Key Features

• Form factors: Desktop, PXIe module, Benchtop, Rackmount, Portable
• Dual-channel benchtop model (LSX2092B)
• Fast switching speed: ultra-fast switching down to 10 μs
• Coherent frequency switching (phase-coherent multi-channel operation)
• Modulation: AM, FM, PM, Sweep, Pulse; pattern modulation supported
• Digital and analog interfaces: LAN, USB, SPI (integrated)
• Remote control and programming: industry-standard SCPI/VISA; supported with Python, MATLAB, C#/C++, LabVIEW and a virtual front panel

Signal Integrity and Purity
The Lucid-X family provides exceptionally low phase noise and excellent spectral purity engineered for demanding RF/MW applications. Representative phase-noise and spectral figures (typical):

• Phase noise (10 kHz offset): -148 dBc/Hz @ 100 MHz
• Phase noise (10 kHz offset): -133 dBc/Hz @ 1 GHz
• Phase noise (10 kHz offset): -114 dBc/Hz @ 10 GHz
• Harmonics typically: -50 dBc
• Non-harmonic spurious typically: -90 dBc

Modulation and Pulse Performance

• FM: maximum deviations up to 10 MHz; modulation rates up to 1 MHz
• AM: linear depth up to 90%; modulation rates up to 100 kHz
• PM: peak deviation up to 360°
• Pulse modulation: high on/off ratio (typically 70 dB); rise/fall times < 15 ns
• Pattern and sequence (list) modes supported for complex signal generation

Control & Programming
The instrument implements SCPI/VISA architecture for seamless integration. Remote control supported over LAN and USB, with example programming environments including Python, MATLAB, C#/C++ and NI LabVIEW. A virtual front panel is provided for local or networked GUI control.
