Keysight Dual-Channel Signal Generator Doubles Testing Capacity in the Same Rack Space

Keysight has introduced a dual-channel analog signal generator that packs two independent 20 GHz sources into a single 2U chassis. The PSG XG7-class instrument enables engineers to run multiple test conditions without adding another instrument or expanding rack space.

Key Characteristics

• Architecture: Dual independent channels in one instrument
• Frequency range: Up to 20 GHz per channel
• Form factor: Compact 2U 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
• Supports Standard Commands for Programmable Instruments (SCPI)
• Rear-panel connections and settings compatible with previous-generation instruments

By combining two high-performance sources in one chassis, the generator effectively doubles signal-testing capacity while preserving signal purity and existing rack configurations.

Target Applications

• Aerospace and defence testing
• Advanced wireless systems
• High-speed digital test environments
• Complex multi-signal test setups requiring high signal integrity

The instrument allows engineers to create independent test conditions from a single unit, reducing equipment count and rack space while maintaining low noise performance essential for accurate high-frequency measurements.
