Signal generator LSX8081X

microwaveRFsingle-channel

Overview
The Lucid-X (LSX) family is a small-footprint modular microwave signal generator platform engineered for high spectral purity, low phase noise and flexible deployment. The LSX8081X is the 8 GHz single-channel PXIe variant, suitable for LO generation, ADC/DAC clocking, radar/EW simulation and automated RF test systems.

Key features

• 8 GHz single-channel PXIe microwave signal generator (model LSX8081X)
• Fast frequency switching: 10 µs switching capability
• Coherent frequency switching for phase-stable transitions
• Modulation: AM, FM, PM, Sweep and Pulse
• Integrated interfaces: LAN, USB and SPI
• Designed for low phase noise and high signal integrity

Signal integrity and purity
The Lucid-X family delivers industry-grade spectral purity and low phase noise across its range. Typical phase noise at a 10 kHz offset: -148 dBc/Hz @ 100 MHz, -133 dBc/Hz @ 1 GHz, -114 dBc/Hz @ 10 GHz. Harmonics are typically below -50 dBc and non-harmonic spurious below -90 dBc, supporting demanding LO, intermodulation and clocking applications.

Analog and pulse modulation
The instrument provides comprehensive analog and pulsed modulation capabilities:

• FM: up to ±10 MHz deviation, 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 (typ. 70 dB) with fast rise/fall times <15 ns

Fast frequency switching
10 µs switching time (ultra-fast switching option available on compatible form factors), enabling simulation of frequency-hopping signals, radar/EW scenarios and high-throughput automated test environments.

Control and programming
Tabor Lucid-X supports SCPI and VISA command sets and can be controlled via LAN or USB. Integration is supported with Python, MATLAB, C#/C++, and NI tools (LabVIEW). A virtual front panel provides an intuitive GUI for local or remote control.

Form factors & interfaces

• Available form factors: PXIe module (LSX8081X), Desktop, Benchtop, Rackmount, Portable
