Standard pattern data Description
Binary up counter Creates a binary up counter data pattern. The cursor becomes the
area cursor. The number of bits in the counter is the total number
of bits in the group set up with the Set scope item in the Execute
Action menu. When Binary up counter is selected, the instrument
asks for the Points/Step value. This value sets the number of data
points per counter step. When the counter reaches its maximum
value, the value returns to 0 and it repeats the countĆup operation.
Binary down counter The use is the same as Binary up counter. The action is the same
except that a binary down counter is created. When the counter
reaches 0, the value returns to its maximum value and the
countĆdown operation is repeated.
Johnson counter Creates a Johnson counter data pattern. When this menu item is
selected, the instrument asks for the Points/Step value. This value
sets the number of data points per counter step.
Graycode counter Creates a Gray code counter data pattern. When this menu item is
selected, the instrument asks for the Points/Step value. This value
sets the number of data points per counter step.
