microwaveRFsingle-channel

Overview
The Lucid‑X LSX2091X is a PXIe single‑channel 20 GHz microwave signal generator designed for high‑performance RF/MW test applications. It delivers excellent spectral purity, low phase noise and coherent operation suitable for multi‑channel systems.

Key summary
The LSX2091X provides a compact PXIe form factor, single output channel up to 20 GHz, extensive modulation features and fast coherent frequency switching for demanding laboratory and production test environments.

Main capabilities

• Fast switching: <100 μs standard; UFS option 10 μs
• Coherent frequency switching for phase‑coherent multi‑channel setups
• Modulation: AM, FM, PM, Sweep, Pulse, Pattern
• Phase noise examples: -148 dBc/Hz @100 MHz (10 kHz offset); -133 dBc/Hz @1 GHz (10 kHz offset); -114 dBc/Hz @10 GHz (10 kHz offset)
• Spurious: harmonics typically -50 dBc; non‑harmonics typically -90 dBc
• Interfaces: LAN, USB, SPI (integrated)
• Control & programming: SCPI/VISA; compatible with Python, MATLAB, C#/C++, LabVIEW; virtual front panel included

Analog, Pulse and Pattern Modulation
The LSX family supports advanced modulation:

• FM: up to 10 MHz deviation, rates to 1 MHz
• AM: linear depth to 90%, rates to 100 kHz
• PM: peak deviation up to 360°
• Pulse modulation: high on/off ratio (~70 dB), rise/fall times <15 ns
• Pattern modulation available

Signal integrity & typical applications
The device delivers the spectral purity and phase‑noise characteristics required for LO/STALO use, intermodulation testing, DAC/ADC clocking, radar and EW testbeds, phased‑array/beam‑forming systems, quantum control/readout and advanced RF research.
