Keysight says its PSG XG7-class (SG6311A) analog signal generator puts two fully independent channels, each in a 20 GHz product class, into one 2U chassis. That can provide two signal sources without adding a second generator’s rack footprint. It does not, by itself, guarantee twice the test throughput: that depends on whether both channels can serve the required conditions at the same time, along with the DUT connections, switching, calibration and automation.
What the dual-channel generator changes
In its September 29, 2026 announcement, Keysight describes the PSG XG7-class as a 20 GHz analog signal generator with two fully independent channels housed in a single 2U chassis. The company’s stated advantage is greater test capacity without increasing rack space. For a setup that needs two generated signals, consolidating those sources in one chassis may reduce instrument count and free rack space compared with adding another generator.
That is a form-factor and channel-count proposition, not a measured throughput result. Whether two channels let a team complete more tests per hour depends on the test sequence, DUT count and connections, switching and calibration needs, and the automation used. The announcement does not quantify a throughput increase or establish that every test condition can run concurrently.

| Claim | Keysight’s stated figure and condition |
|---|---|
| Maximum frequency / product class | 20 GHz |
| Channels and chassis | Two fully independent channels in one 2U chassis |
| Phase noise | −135 dBc/Hz at 10 GHz with a 10 kHz offset |
| Amplitude modulation noise | −150 dBc/Hz at 10 GHz with a 10 kHz offset |
| Broadband noise floor | −166 dBc/Hz at 10 GHz |
| Calibrated output power | Up to +22 dBm |
Keysight says the calibrated output power can help maintain required levels at the device under test (DUT) despite losses in cables and fixtures. The usable level at the DUT still depends on the signal path, and the generator and DUT must remain within their operating limits. The announcement does not provide a complete specification sheet, so engineers should verify the values and conditions needed for their application against the instrument’s full documentation.
Check the delivered signal, not just the generator setting
The generator’s front-panel level is not automatically the level that reaches the DUT. Cables, connectors, attenuators and fixtures add loss and can introduce mismatch or reflections. Where accuracy requirements call for it, calibrate or correct for the setup’s path loss. Keysight’s announcement discusses lossy cables and fixtures; Mini-Circuits’ S-parameter guidance advises calibrating the setup as instructed, using the DUT’s specified characteristic impedance, and connecting matched terminations to unused ports on multiport devices.

- 【Multiple Interfaces to Choose】 Main interface programmable output. Input waveform interface: switchable input current graph display, input voltage graph display. VCA conversion interface: switchable voltage to active current, voltage to passive current, current to voltage. Automatic interface: automatic mode can be set for single ascent, single drop, and loop. PWM interface: Output PWM signal, voltage, frequency, and duty cycle can be set

Plan isolation and matching for two-source tests
Two independent channels are useful only if the signals stay suitable for the measurement after they are combined or routed to the DUT. In two-tone and intermodulation tests, inadequate source isolation can allow one generator to interact with the other. Harmonics and other unwanted products can also reach the DUT unless the signal paths are appropriately filtered.
Mini-Circuits’ two-tone measurement guidance describes using amplifiers, matching pads and a power combiner to improve isolation and preserve impedance matches. Its signal-splitting guidance explains that the relevant splitter specification depends on the application. There is no single isolation target or combiner arrangement that can be assumed suitable for every frequency, signal level and DUT; select components and filtering for the actual test conditions.

For some gain, compression and power measurements, a power splitter can support ratioing or leveling, improve source match and reduce the effects of re-reflections in the described setup. That is a measurement technique, not a requirement for every configuration or a specific feature claim about the PSG XG7-class; see Keysight’s power-splitter measurement note.

Keysight says the generator supports SCPI and uses familiar rear-panel connections and settings aligned with previous-generation instruments, which may help teams reuse automation. That does not establish universal drop-in compatibility. Check the commands, connection layout, cabling, instrument configuration and control behavior against the particular rack and software before treating an existing test program as reusable. The announcement does not give channel-synchronization details or a complete compatibility matrix.
