Reference Solution Configuration
Signal creation configuration
The testbed signal generation hardware includes the M8190A AXIe AWG installed in an
AXIe chassis that also contains an embedded controller. The 81199A software runs on
the embedded controller, which creates waveforms that are loaded in the AWG installed
in the same chassis. The 2-channel precision AWG can operate with 14-bit resolution at
up to 8 GSa/s or 12-bit resolution up to 12 GSa/s. It offers 5 GHz of analog bandwidth
and 2 GSa of memory per channel.
As part of the reference solution, the AWG is used to drive a PSG vector signal generator
equipped with wideband differential external I/Q inputs (option 016). The wideband
inputs can produce modulation bandwidths of up to 2 GHz on carrier signals up to
44 GHz. Depending on your application and performance requirements, a choice of
upconverters is available to generate signals in V-Band. The Keysight N5152A offers
a frequency range of 57 to 66 GHz, and Virginia Diodes, Inc. has a number of different
upconverters available in V-Band (50 to 75 GHz), E-Band (60 - 90 GHz), and beyond.
MXG or PSG microwave analog signal generators provide the LOs for the millimeter-wave
upconverters.
The creation of 802.11ad waveforms is controlled by the 81199A software, which provides
fully coded and modulated PHY signal generation. The software provides a library of
individually-configurable waveform segments. Assembling a desired signal is a simple
matter of dragging and dropping waveform segments and then assigning essential
attributes to them. Before downloading to the arbitrary waveform generator at an
appropriate sample rate, you can also add Additive White Gaussian Noise (AWGN) and
other impairments.
