30 M8100 Series Arbitrary Waveform Generators Getting Started Guide
1 Introduction
 
M8199B Arbitrary Waveform Generator
Keysight’s M8199B 256 GSa/s Arbitrary Waveform Generator (AWG) is a 
high-performance signal source for arbitrary signals, with the highest 
sample rate and the widest bandwidth in its class. The M8199B enables 
generation of high-quality signals of up to 160 GBd in a 2-slot AXIe 
module.
For applications beyond 128 GBd, the M8199B AWG is the ideal solution 
where it provides high-speed and precise testing of various optical 
systems, and it provides stress signals to test next generator digital signal 
processor ASICs and new algorithm concepts. The flexibility of the 
waveform generator with high speeds, combined with excellent intrinsic 
jitter performances makes the M8199B a truly unique and versatile 
instrument for Intensity-Modulation/Direct-Detect (IM/DD) optical 
applications.
The M8199B AWG also allows you to generate any arbitrary waveform that 
can be mathematically described and can be used for physics, chemistry, 
and general-purpose electronics research.
The key benefits of using the M8199B Arbitrary Waveform Generator are:
• Provides up to eight synchronized channels at 256 GSa/s with a 
nominal 3dB-bandwidth of 75 GHz including sinc-rolloff
• enables development of designs of higher-order QAM (such as 64 QAM) 
at 160 GBd and above
• enables 400+ Gb/s per lane in IM/DD or 1.6+ Tb/s per carrier in 
coherent optical communications
• Integrated, ready-to-use instrument, works with M8008A clock module
• Operates with well-known software, including MATLAB, Keysight 
IQtools, and SCPI programming interfaced based on M8070B
• Built-in frequency and phase response calibration for clean output 
signals
The M8199B is an instrument module that can be installed into the 
M9505A 5-slot AXIe Chassis. This module occupies two slots of the 5-slot 
chassis. It must be installed in the slot immediately above the M8008A 
Clock Generator module. The M8008A module must be installed in slot 1; 
therefore, the M8199B module must be installed in slots 2 and 3 of the 
AXIe chassis.
If the M9537A AXIe Embedded Controller is also being used, the Controller 
module must be installed in slot 1, followed by the M8008A module in slot 
2 and M8199B module in slots 3 and 4, respectively.
