8240x Series Millimeter-Wave & THz Modules
Ceyear 8240x series frequency extension modules extend the operational frequency of vector network analyzers and spectrum analyzers into millimeter-wave and terahertz bands: 110, 170, 220, 325, and 500 GHz.
Incorporating precision waveguide interfaces, directional couplers, balanced mixers, and multiplier chains, they maintain low conversion loss and high dynamic range.
Each millimeter-wave extension head incorporates factory calibration data stored in onboard EEPROM for automatic frequency response correction and linearity enhancement.
Waveguide flanges from WR-15 to WR-03 provide standardized coupling to research devices and planar probes.
Ceyear 20404 series electronic calibration modules (ECAL) and 311xx mechanical verification kits deliver metrology-grade calibration for vector network analyzers up to 67 GHz.
The USB-controlled ECAL module completes full two-port or four-port calibration in seconds, drastically reducing operator handling while eliminating connector wear.
Electronic calibration eliminates mechanical re-connection uncertainties, minimizes port wear, and guarantees seamless metrological traceability to national measurement standards.
Available in 3.5 mm, 2.92 mm, 2.4 mm, and 1.85 mm connector standards with traceable calibration certificates.

Selecting a Ceyear Measurement Instrument
Begin with the upper frequency boundary and signal characteristics. For spectrum analyzers, verify displayed average noise level (DANL) and real-time bandwidth; for vector network analyzers, consider port count and dynamic range. Check RF connector types and internal step attenuator options.
Spare parts and RF assemblies
Mixer modules, input protection attenuators, YIG synthesizers, processor boards, and internal power supplies are identified by chassis serial number and PCB hardware revision. Matching external series names alone does not guarantee modular interchangeability.
Ceyear Technologies Co., Ltd. Profile
, Ltd. (formerly the 41st Research Institute of CETC) is headquartered in Qingdao, Shandong Province, China. The enterprise is a premier Chinese manufacturer of electronic test and measurement instruments spanning microwave, millimeter-wave, optical, and general electronic domains.
Its portfolio covers benchtop and handheld units, automated test benches, and precision RF passive components.
Measurement Domain Categorization
Instrument selection depends on the RF transmission characteristics to be evaluated. For spectral purity, harmonic analysis, and modulation analysis, the 4051 series spectrum analyzers provide superior fidelity.
For measuring complex reflection and transmission S-parameters of active and passive devices, the 3672 series vector network analyzers deliver laboratory-grade accuracy.
Frequency Coverage and RF Connector Standards
Operating frequency dictates the mechanical design of RF test ports. 85 mm (V-type) interfaces. Millimeter-wave bands above 70 GHz connect via standard waveguide flanges such as WR-15, WR-10, and WR-03.
Dynamic Range and Noise Performance
When characterizing high-rejection filters and diplexers, the vector network analyzer dynamic range is crucial, exceeding 125 dB in the 3672 series.
In spectrum analyzers, displayed average noise level (DANL) and close-in phase noise govern the ability to resolve low-level spurious emissions and intermodulation sidebands in communication channels.
Calibration Standards and Traceability
Achieving metrology-grade accuracy requires rigorous error-correction routines. Ceyear 20404 series electronic calibration modules (ECAL) automate complete two-port or four-port calibration in a single connection cycle.
For high-frequency laboratory verification, 311xx series mechanical calibration kits provide certified open, short, load, and thru standards.
Hardware Options and Software Capabilities
Ceyear instruments support scalable modular expansion via licensed firmware and internal option cards. Spectrum analyzers accommodate phase noise measurement suites, analog/digital modulation demodulation, and spectrogram analysis.
Network analyzers support time-domain transform (TDR), mixer frequency-conversion characterization, and high-power sweep options.
Technical Inquiry Formulation
When submitting an equipment inquiry, clearly state upper and lower frequency bounds, test port requirements, frequency tuning resolution, measurement speed, and device-under-test (DUT) power handling.
Providing a complete test plan ensures accurate matching with available Ceyear instrument platforms.
