Auxiliary Channels
Outputs
Trigger output
The trigger output can be enabled
or disabled. The levels of the trigger
output can be set as high level or low
level pair.
The trigger output can be set to one
of the following modes:
• Trigger on clock
The frequency of the trigger
output is identical to the
system frequency. It can be
further divided by n (n= 1, 2, 3, 4,
5, 6, 7…2 31 -1).
• Trigger on data
One Trigger pulse occurs on
the first part of the repetitive
data pattern.
Inputs
Note: The built-in input and output
terminations eliminate the need for
external bias networks and prevent
a degrading of the input/output
sensitivity
Clock input
The clock input can be ‘AC’ or ‘DC’
terminated. The ‘DC’ termination
voltage can be set. See also ‘Clock
Source - external’.
Start input
The start input can be used to start
the instrument. After being armed,
the instrument waits for the selected
edge of the applied signal.
Parameters:
• Threshold (voltage)
• Edge (rising/falling)
• Termination voltage
Store/Recall
Allows permanent storage of instru-
ment settings, including all signal
parameters and data settings. Data
patterns up to 8K bit length are also
stored. The instrument provides
memory for 9 different settings.
In addition, the 81133A and 81134A
stores the current settings at
shutdown and restored them on next
power-on.
For data patterns with more than 8K
Bit length, it is recommended to use
the special PC-based pattern editor.
Overprogramming
Many parameters can be programmed
to values that exceed the specified
ranges.
