VXG signal generators are designed for 5G and 6G research, satellite communications and radar solutions.
Keysight Technologies, Inc. an innovative technology company providing design and validation solutions to connect and secure the world, has designed a new four-channel vector signal generator with a frequency of up to 54 GHz, offering up to 5 GHz of radio frequency (RF) bandwidth and low phase noise in a single instrument.
Keysight's new M9484C VXG vector signal generator enhances its VXG series product range with real-time functionality to support the wireless industry's most demanding applications. The M9484C VXG signal generator, combined with a V3080A frequency extender, extends the frequency range up to 110 GHz to meet the needs of current and future standards.
The new 5G mobile communications, 6G research, satellite communications and radar applications use a wide range of frequencies, right up to the millimeter-wave (mmWave) spectrum. Testing these applications requires signal generation equipment capable of creating mmWave signals at extremely high bandwidths. These new applications also adopt multi-antenna techniques, such as spatial diversity, spatial multiplexing and beamforming, to enable diversity, multiplexing and antenna gains for robust, high-speed communications.
Keysight's new M9484C VXG signal generator enables customers to reduce the complexity of test system configuration and achieve accurate, repeatable multi-channel measurements in a single instrument. Key benefits for customers include:
● Scalable architecture which enables the most demanding broadband and multichannel signal testing at frequencies up to 110 GHz:
○ Generates test signals with radio frequency (RF) bandwidth up to 5 GHz ;
○ Covers frequency ranges from 9 kHz to 54 GHz and up to 110 GHz with a frequency-extended V3080A vector signal generator ;
○ Enables multi-antenna test applications such as MIMO and beamforming with precise phase coherence and synchronization timing.
● Fully integrated, calibrated and synchronized signal generator which offers low phase noise and minimizes measurement uncertainty:
○ Overcomes excessive path loss observed at mmW frequencies with low error vector magnitude (EVM) and low distortion at high output power ;
○ Offers advanced RF performance with direct digital synthesis (DDS) technology to accurately characterize devices under test (DUT) ;
○ Enables precise synchronization and triggering of multi-channel / multi-instrument test applications.
● Real-time signal processing and complete signal creation that enable elaborate test scenarios and simplify the complexity of acceptance and performance tests.
○ Supports real-time MIMO fading for all base station compliance tests required by the 3GPP 5G new radio (NR) standard with PathWave Signal Generation software.
○ Streamline complex receiver test scenarios with emulation of 8 virtual signals per RF channel, up to 32 signals in a single instrument.
○ Simplify test routines with predefined compliance test configurations, automatic signal analysis and graphical user interface.
Keysight's new M9484C VXG signal generator generates high-frequency, high-bandwidth signals in multiple coherent channels. These capabilities enable engineers to :
