Does improved production efficiency in industrial testing eventually benefit the average consumer?
Keysight Technologies has released the SG6311A, a 20 GHz analog signal generator equipped with two independent signal-generation channels. This new instrument is designed to maximize test capacity while maintaining a compact 2U rack-mount form factor.
Why it matters
The dual-channel architecture allows engineers to double their testing capacity without requiring additional rack space. High calibrated output power also helps compensate for signal losses often experienced during long cable runs in complex test setups.
The SG6311A delivers a broadband noise floor of -166 dBc/Hz and an amplitude modulation noise of -150 dBc/Hz at 10 kHz offsets at 10 GHz. The device supports SCPI commands for automation and maintains compatibility with previous PSG rear-panel connections.
The players
Keysight Technologies
This company is a leading provider of electronic design and test instrumentation for engineers and scientists.
The details
Operating up to 20 GHz, the unit utilizes a hybrid architecture with software-based mode switching to manage signal paths. The device provides up to +22 dBm of calibrated output power to ensure signal integrity across extensive testing configurations.
Timeline
October 20, 2026: Keysight Technologies introduced the SG6311A signal generator.
The Tech Race
This release reflects the broader industry trend of maximizing hardware density as testing demands for high-frequency electronics grow. It extends the established legacy of the Keysight PSG series by maintaining rear-panel compatibility while modernizing the signal path architecture.
Engineers can utilize SCPI commands to automate complex test sequences, reducing the time required for manual configurations. The compact 2U design allows testing teams to increase their throughput within existing laboratory rack space.
The takeaway
The SG6311A provides a high-density solution for laboratories looking to expand testing capabilities without expanding their physical footprint. By integrating dual-channel generation and high power output, it serves as a pragmatic upgrade for demanding signal testing environments.
