Generate the most complex wideband signals
Keysight XG7-class Pro vector signal generators include the VXG Series. Pro vector signal generators extend frequency support up to 54 GHz, or 110 GHz with a frequency extender, and bandwidth up to 2.5 GHz while supporting direct digital synthesis, embedded software, and other key features of our Expert models. Additional capabilities include channel bonding, providing up to 10 GHz bandwidth per instrument, real-time fading including custom fading models with signal generation software, and eight virtual signal generators per RF channel or 32 emulated transmitters in a single unit.

Frequently asked questions
The Pro+ signal generator offers eight virtual signal generators (multiple IQ paths to RF), enabling you to emulate up to eight signals simultaneously using one channel. This feature is particularly advantageous in receiver design and testing applications, where the current method often requires RF combining multiple signal generators due to dynamic range limitations. The 8 virtual signal generators can simplify device characterization when multi-carrier or multi-radio access technology signals are necessary.
Fading refers to the change in a signal's attenuation caused by various factors, including geographic position, time, and frequency. Fading, also known as channel simulation, enables users to apply degradations to signals to simulate real-world conditions. Real-world causes of fading include multipath propagation (where the signal reflects off various obstacles along its path), multipath fading, and environmental factors such as weather (like rain) and obstacles that affect signal propagation.
Obstacles surrounding the transmitter and receiver create multiple paths for the transmitted signal to travel. The receiver sees a summation of multiple copies of the transmitted signal that have traveled different paths. On the journey from source to receiver, each received signal will arrive with differences in attenuation, delay, and phase shift, which may result in constructive or destructive interference.
RF channel bonding is a technique used in wireless communication systems to combine multiple RF channels into a single, wider channel to increase data throughput. This capability can help support applications such as generating wide-band QPSK and 5G NR waveforms.
