Emulate effects like...
• Capacitive load of the channel
• Asymmetric delay
• Crossing point deviations
• Duty cycle distortions
• Arbitrary transition times
• Level noise
• Delays from/to electrical idle
...By defi ning the transitions so that the
previous bit infl uences the current bit
Stress your device to its limits–defi ne your own bit shape
The 81150A and the 81160A pattern generators let you defi ne the transitions from one bit
to the other so that the previous bit infl uences the current bit. The user can set up own
defi ned arbitrary bit shapes.
In addition to user-defi ned patterns, standard patterns like PRBS up to 2
The sequencer allows setting up a pre-amble sequence so that the device under test
moves into test mode.
With the 3-level signals it is no longer necessary to add different signals for electrical idle.
Up to 4 levels are available in the expert mode.
Besides, standard trigger modes like continuous bit and block trigger modes allow adop-
tions to application needs. In the bit mode you see that on every trigger, the sequence
is advanced by one bit. An application example is a bit clock, which can be fed into an
external clock and then into the trigger input.
In the block mode the entire data block is generated once per trigger event. This is
interesting for example in applications with protocol data.
The 81150A and the 81160A pattern generators pass the data through to the device
under test and adopts it to any kind of stress test (shape and timing change).
Bridge the gap between protocol and physical layer test – in real time up to 10 Mbit/s
Increase your test efficiency by combining physical layer test with protocol test
The pass-through pattern functionality takes the protocol data via “mod in” and adopts it
to any kind of stress test (shape and timing changes).
