Keysight signal generators make up one of the industry's broadest signal-source portfolios, spanning baseband through 67 GHz with frequency extensions reaching 1.1 THz. The line supports the design and manufacture of radio transceivers and their components, and every generator delivers synthesized frequency accuracy and stability, calibrated level accuracy, and remote programmability. The portfolio is offered in two form factors: benchtop instruments and modular PXI.

Application coverage runs from low-frequency navigation signals, through cellular mobile radio, to millimeter-wave radar and satellite systems. The agile members of the line are built for electronic warfare (EW) and radar work, where extensive pulse modulation, wideband chirp, and phase-coherent operation matter. Vector models pair with a baseband generator to emulate and transmit virtually any signal within the system's information bandwidth, while analog models supply sinusoidal continuous-wave (CW) signals with optional AM, FM, ΦM, and pulse modulation for passive device characterization or calibration.

ValueTronics stocks test and measurement equipment in our own 20,000 sq ft secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Every pre-owned unit we sell is inspected and functionally verified by our technicians before it ships, while new units ship factory-sealed exactly as received from the manufacturer. That combination of real, in-house inventory and hands-on verification is the difference between buying from a stocking specialist and buying from a listing.

Brand Heritage

Keysight Technologies traces its test-and-measurement lineage to Hewlett-Packard, whose instrument business was spun out as Agilent Technologies in 1999. Agilent's electronic measurement division then became Keysight Technologies in 2014, the brand under which this line is produced today.

Compare Other Models in This Series

Keysight offers one of the industry's widest selections of signal generators, spanning baseband through 67 GHz with frequency extensions to 1.1 THz. The portfolio addresses the design and manufacture of radio transceivers and their components, with applications ranging from low-frequency navigation signals, through cellular mobile radio, to millimeter-wave radar and satellite systems. Every model provides synthesized frequency accuracy and stability, calibrated level accuracy, and remote programmability.

The family is organized by type and form factor: analog generators supplying sinusoidal CW with optional AM, FM, ΦM, and pulse modulation; vector generators with built-in I/Q modulators for complex formats such as QPSK and 1024QAM; and agile generators optimized for fast frequency, amplitude, and phase changes with phase-coherent operation for EW and radar. Both benchtop and modular PXI versions are available, and the PXI vector generator shares the same software applications as the benchtop models.

Each pre-owned model linked below is its own dedicated product page with condition-matched pricing. Select the specific model number and frequency range that fits your application, and the page for that pre-owned unit will show its own specifications and availability.

The models differ primarily by frequency range, generator type, and form factor. On the RF side, the X-Series MXG (N5182B vector, N5181B analog) and EXG (N5172B vector, N5171B analog) cover 9 kHz to 6 GHz, while the N9310A analog RF generator covers 9 kHz to 3 GHz. On the microwave side, the MXG (N5183B) and EXG (N5173B) reach 40 GHz, and the PSG provides 100 kHz to 44 GHz in the vector E8267D and 100 kHz to 70 GHz in the analog E8257D.

Modular PXI options include the M9381A PXIe vector signal generator and M9380A PXIe CW source, both covering 1 MHz to 6 GHz. The UXG agile line (N5193A, with the N5194A vector adapter) targets multi-emitter threat simulation for EW test. The comparison table that follows lists each model's frequency range, output power, level accuracy, phase noise, and modulation specifications side by side so you can match a model to your requirement.

Additional differences in specifications beyond the few shown above are not listed here — see each model's full specifications below.

Product Core & Specifications

Important: Export control: because of its high-performance characteristics, the N5193A UXG agile signal generator requires a US export license; the N5191A is a modified version that provides high performance without requiring an export license. The multi-emitter scenario generation (MESG) software is also subject to ITAR export controls.

Important: The MESG (multi-emitter scenario generation) software is subject to ITAR export controls; for more information, contact your Keysight sales representative.

Important: Millimeter-wave frequency coverage above the base PSG range requires external modules ordered separately: the E8257DSxx-Series millimeter-wave source modules from OML, Inc. cover waveguide bands from 50 to 500 GHz, and the E8257DVxx-Series frequency extension modules from VDI, Inc. cover waveguide bands from 50 GHz to 1.1 THz, for the E8257D and E8267D PSG signal generators.

Recommended pairing: the N5194A UXG agile vector adapter works together with the N5193A UXG agile signal generator to simulate more complex signal environments with shaped pulses and wideband linear or non-linear chirps.
