Signal generator LSX4091R

microwaveRFsingle-channel

Overview
The Lucid-X LSX family provides small-footprint, modular microwave signal generators available in multiple form factors (Desktop, PXIe module, Benchtop, Rackmount 19" 1U, Portable). The LSX4091R is a 40 GHz single-channel rackmount unit designed for low phase-noise performance, coherent frequency switching and easy integration into automated test and instrumentation environments.

Key Highlights

• Form factors: Desktop, PXIe module, Benchtop, Rackmount (19" 1U), Portable
• Frequency range: up to 40 GHz
• Low phase noise suitable for LO, IMD testing and high-performance DAC/ADC clocking
• Fast frequency switching: 10 µs (ultra-fast mode where specified)
• Coherent frequency switching for phase-coherent multi-channel applications
• Modulation: AM, FM, PM, Sweep, Pulse, Pattern
• Integrated interfaces: LAN, USB, SPI; SCPI/VISA support and remote control via Python, MATLAB, C#/C++, LabVIEW

Features (detailed)

• Phase noise performance (example offsets): -148 dBc/Hz @100 MHz (10 kHz offset); -133 dBc/Hz @1 GHz (10 kHz offset); -114 dBc/Hz @10 GHz (10 kHz offset). Harmonics typically ≈ -50 dBc; non-harmonics ≈ -90 dBc.
• Analog modulation: FM (deviation 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°).
• Pulse modulation: high ON/OFF ratio (typically 70 dB) with fast rise/fall times <15 ns.
• Fast/ultra-fast frequency switching options (100 µs / 10 µs) to support frequency-hopping, automated test throughput and dynamic RF simulations.
• Control & programming: SCPI/VISA compatible; virtual front panel included; remote integration supported via Python, MATLAB, C#/C++, LabVIEW.
