Keysight Technologies has introduced the Pro XG7-class SG6311A PSG Analog Signal Generator — a dual-channel instrument that combines two fully independent 20 GHz sources in a compact 2U chassis. The design increases test capacity without requiring additional rack space while delivering clean stimulus signals for high-performance device characterisation.

Key Characteristics
- Frequency range: up to 20 GHz
- Channels: two fully independent, configurable signal paths
- Form factor: compact 2U rack-mount chassis
- Phase noise: −135 dBc/Hz at 10 GHz (10 kHz offset)
- Amplitude modulation noise: −150 dBc/Hz at 10 GHz (10 kHz offset)
- Broadband noise floor: −166 dBc/Hz at 10 GHz
- Calibrated output power: up to +22 dBm
- Architecture: hybrid design with software-based mode switching
- Control: full SCPI support for automation
- Rear-panel connections and settings compatible with previous-generation instruments
The low-noise performance helps engineers distinguish subtle device behaviour from source-induced artefacts, while the dual-channel architecture allows simultaneous independent signal generation from a single instrument.
Target Applications
- Aerospace and defence testing
- Advanced wireless communications
- High-speed digital system development
- Device characterisation requiring clean RF stimulus
By packing two high-performance sources into one 2U unit, the SG6311A expands measurement capability while preserving existing rack configurations and automation workflows.
