Keysight Unveils Dual-Channel Analog Signal Generator for Advanced Device Testing

Keysight Technologies announced the launch of a 20 GHz PSG XG7-class analog signal generator. Keysight said that demanding test environments exist in aerospace and defense, advanced wireless communications, and high-speed digital applications, and that source noise can obscure the actual behavior of the device under test.

In such environments, engineering teams face the challenge of efficiently using limited rack space while avoiding costly changes to existing test systems and, at the same time, expanding test capacity, Keysight said. Against the backdrop of limited equipment space and growing difficulty in performance evaluation due to noise issues, the new signal generator was introduced.

The product is characterized by integrating 2 fully independent channels into a single 2U-high chassis. Keysight said the compact dual-channel design makes it possible to expand test capacity without additional rack space.

Keysight also said the product delivers excellent low-noise performance and calibrated output power. The company said this improves clarity, enabling engineers to evaluate device performance more clearly.

Keysight said the new PSG delivers low phase noise, low amplitude modulation noise, a low broadband noise floor, calibrated output power, and 2 independent channels in a compact chassis. Keysight said these specifications address industry requirements.

Keysight said the new XG7-class ultra-low-noise performance significantly improves measurement visibility. It also said the signal source minimizes the impact of obscuring critical device behavior, allowing engineers to accurately evaluate the actual performance of the device under test.

The new PSG integrates 2 fully independent channels into a compact 2U chassis. As a result, it can increase the number of simultaneous tests without expanding existing rack space and also supports capacity expansion, Keysight said.

Keysight also said it provides clean, calibrated output power of up to +22dBm. This allows the required signal level at the DUT to be maintained stably even after passing through lossy cables and test fixtures, the company added.

The instrument supports SCPI (Standard Commands for Programmable Instruments) compatibility, adopts a familiar rear-panel connection layout, and includes a configuration environment compatible with the previous generation of equipment. Based on this, existing automation programs and existing test procedures can be reused. It also enables faster transitions to next-generation technologies through reuse of existing assets.

The PSG features a -135dBc/Hz phase noise specification at a 10GHz carrier frequency and 10kHz offset. It also delivers amplitude modulation noise of -150dBc/Hz and a broadband noise floor of -166dBc/Hz at 10GHz.

The instrument applies a hybrid architecture that uses software mode switching to optimize performance across a range of applications. It also supports calibrated output power of up to +22dBm to compensate for signal loss in cables and test fixtures.

"Engineers have long used Keysight PSG signal generators because they deliver reliable performance even in the most demanding measurement environments," said Choi Jun-ho, vice president of Keysight's Core Products division. He added that the new analog signal generator provides signal purity, output power, and productivity to help customers accurately characterize device performance and support modernization with greater confidence in the test environment.
