Configuring AWG(s) Parameters
The M8195A/M8196A AWG has the Data Out and Clk Gen ports. You can
use the Parameters window to configure these ports.
• Line Coding - Sets the line coding as NRZ or PAM4.
• Amplifier - The Amplifier function has the following components:
• Amplitude - Sets the amplitude of the output signal.
• Offset - Sets the offset voltage of output signal.
• High - Sets the high voltage of output signal.
• Low - Sets the low voltage of output signal.
• Pulse Shaping Filter - Sets the filter type used on the waveform. The
filter type choices are Gaussian and Raised Cosine. Depending upon
the specific waveform used, the waveform gets properties like
transition time or roll-off factor. This parameter is only available in
M8196A.
• Roll-Off Factor - Sets the roll-off factor for the raised cosine pulse
shaping filter. This parameter is only available in M8196A.
• Transition Time - Sets the transition time (20%/80%) of data output
signal.
• Crossover - Sets the data's crossover percentage.
• Deemphasis - Sets the deemphasis values in terms of coefficient
values. You can set the two post-cursor, main cursor and two
pre-cursor by adjusting the coefficient values. For details, see
De-Emphasis Signal Generator on page 266.
• Output Timing - Sets the delay of the output data signal.
• HF Jitter- Enables and sets the high frequency jitter.
• Embedding - Sets the S-Parameter for embedding.
• De-Embedding - The De-Embedding function has the following
components:
• Channel Specific - Applies channel specific correction of the
amplitude and phase using an internal calibration.
• Standard Cable - Defines whether the signal should be
pre-distorted considering the properties of the standard cable set.
• S-Paramter State - Enables/Disables S-Parameter compensation.
• S-Paramter Profile - Selects the S-Parameter profile. It also allows
you to import and export a S-Parameter profile.
• S-Paramter Output Port - Selects the output port in S-Parameter
profile.
