Keysight Technologies on 1st of October, 2026, announced the new 20 gigahertz (GHz) PSG XG7-class analog signal generator, which combines two fully independent channels in a single 2U chassis. Its low noise and calibrated output power help engineers evaluate device performance more clearly, while its compact dual-channel design increases test capacity without requiring additional rack space.
In challenging testing scenarios, such as aerospace and defence, advanced wireless and high-speed digital applications, the noise from the signal source can hide the behaviour engineers need to measure. Engineering teams also need to increase test capacity, while working within limited rack space and without costly modifications to existing test systems. The new PSG meets these needs with low phase noise, low amplitude modulation noise, low broadband noise floor, calibrated output power and two independent channels in a compact 2U chassis.
Key benefits of the new XG7-class include:
- Enhanced measurement visibility: Ultra-low noise helps engineers evaluate device performance without the signal source masking critical behavior.
- Expanded test capacity: Two fully independent channels in a compact 2U chassis enable teams to run more tests without increasing rack space.
- Improved performance in lossy test setups: Clean, calibrated output power up to +22 decibel-milliwatt (dBm) helps maintain the required signal level at the device under test, including through lossy cables and test fixtures.
- Faster technology refresh: Standard Commands for Programmable Instruments (SCPI) compatibility, familiar rear-panel connections and settings aligned with previous-generation instruments help teams reuse existing automation and test procedures.
The PSG provides phase noise of -135 dBc/Hz and amplitude modulation noise of -150 dBc/Hz, measured at 10 GHz with a 10 kHz offset, together with a broadband noise floor of -166 dBc/Hz at 10 GHz. Its hybrid architecture uses software mode switching to optimize performance across different applications, while calibrated output power up to +22 dBm helps compensate for losses in cables and test fixtures.
Jun Chie, Vice President, Keysight Core Product Management, said: “For decades, engineers have relied on Keysight’s PSG signal generators for trusted performance in the most demanding measurement environments. This new analog signal generator builds on that legacy with the purity, power, and productivity customers need to reveal true device performance and modernize test environments with confidence.”
