Signal generator LSX8081B

microwaveRFsingle-channel

Overview
The LSX8081B is the 8 GHz single-channel benchtop member of the Lucid-X modular microwave signal generator family. Designed for test and instrumentation applications, it delivers low phase noise, broad modulation capabilities and configurable fast switching in a compact benchtop form factor.

Key features

• 8 GHz single-channel benchtop microwave signal generator
• Fast switching: <10 μs typical (UFS option); FS option for 100 μs
• Coherent frequency switching for multi-tone and hopping tests
• Analog modulation: AM, FM, PM, Sweep and Pulse
• Integrated LAN and USB interfaces for remote control

Signal integrity and purity
The Lucid-X family provides very low phase noise across its frequency range, suitable for local oscillator, IMD and DAC/ADC clocking applications. Example phase noise (10 kHz offset): -148 dBc/Hz @100 MHz, -133 dBc/Hz @1 GHz, -114 dBc/Hz @10 GHz. Harmonics typically -50 dBc; non-harmonics typically -90 dBc.

Analog and pulse modulation
The LSX8081B supports extensive analog and pulse modulation:

• 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°
• Pulse modulation: high on/off ratio (~70 dB); rise/fall times <15 ns

Fast frequency switching
Fast switching modes (10 μs UFS option, 100 μs FS option) suit automated test, frequency-hopping simulations, radar/EW emulation and high-throughput manufacturing test environments.

Control and programming
Standard SCPI/VISA command set with LAN and USB interfaces. Integration supported via Python, MATLAB, C#/C++, LabVIEW and NI tools. Virtual front panel available for local or remote GUI control.
