3.5 Pattern Capabilities
Introduction
A Pattern is a digital data stream that is stored in volatile or non-volatile
memory, generated algorithmically or provided by an external data source for
re-timing and re-shaping.
 Multi-level patterns, using 2, 3 or 4 different levels, allowing support
for serial protocols that require electrical idle signaling in the data
streams.
 81150A: Up to 16 Mbit long memory 2- level based patterns. Up to 8
Msymbols long memory based 3- and 4-level patterns.
 81160A, 1 channel: Up to 4 Mbit long memory 2- level based patterns.
Up to 2 Msymbols long memory based 3- and 4-level patterns.
 81160A, 2 channels: Up to 2 Mbit long memory 2- level based
patterns. Up to 1 Msymbols long memory based 3- and 4-level
patterns.
 Support for algorithmic PRBS patterns
 Support of one adjustable loop, allowing easy integration of
initialization sequences into the data stream before the actual test
pattern.
 In triggered and gated mode, the pattern can be either controlled on a
per block or per bit basis.
 NRZ formatting or arbitrary bit shapes.
 User definable bit shapes allow emulation of real world signal shapes
that include over- and undershoot, ringing or distorted level
transitions.

Operation
After selecting the pulse function, press the Pattern Setup softkey. This will
show the Pattern Setup screen. Then, press the desirable softkey to change
the parameters.
