ULQRTR (Transition ratio for Upper Left Quadrant Right Clock Track)

: Only for 2 and 4 quadrant symbols, this

is the grade based on the clock track segment to the right of the upper left quadrant. For a 2 quadrant symbol, this

is labeled LQRTR

URQRTR (Transition ratio for Upper Right Quadrant Right Clock Track)

: Only for 2 and 4 quadrant

symbols, this is the grade based on the clock track segment to the right of the upper right quadrant. For 2

quadrant symbols, this is labeled RQRTR.

LLQRTR (Transition ratio for Lower Left Quadrant Right Clock Track)

: Only for 4 quadrant symbols, this

is the grade based on the clock track segment to the right of the lower left quadrant.

LRQRTR (Transition ratio for Lower Right Quadrant Right Clock Track)

: Only for 4 quadrant symbols,

this is the grade based on the clock track segment to the right of the lower right quadrant.

TCT (Top Clock Track)

is a grade based on imperfections in the top clock track. Some imperfections in the clock

track can be tolerated. As a rule maintaining for a passing grade is that three out of every five modules on a

consecutively rolling window of five modules must be correct. The value of the grade is the highest modulation

level for which this test passes.

ULQTCT (Top Clock Track for Upper Left Quadrant)

: Only for 2 and 4 quadrant symbols, this is the

grade based on the clock track segment at the top of the upper left quadrant. For 2 quadrant symbols this

is labeled LQTCT.

URQTCT (Top Clock Track for Upper Right Quadrant)

: Only for 2 and 4 quadrant symbols, this is the

grade based on the clock track segment at the top of the upper right quadrant. For 2 quadrant symbols this

is labeled RQTCT.

LLQTCT (Top Clock Track for Lower Left Quadrant)

: Only for 4 quadrant symbols, this is the grade

based on the clock track segment at the top of the lower left quadrant.

LRQTCT (Top Clock Track for Lower Right Quadrant)

: Only for 4 quadrant symbols, this is the grade

based on the clock track segment at the top of the lower right quadrant.

RCT (Right Clock Track)

is a grade based on imperfection in the right clock track. See Top Clock Track.

ULQRCT (Right Clock Track for Upper Left Quadrant)

: Only for 2 and 4 quadrant symbols, this is the

grade based on the clock track segment to the right of the upper left quadrant. For 2 quadrant symbols,

this is labeled LQRCT.

URQRCT (Right Clock Track for Upper Right Quadrant)

: Only for 2 and 4 quadrant symbols, this is the

grade based on the clock track segment to the right of the upper right quadrant. For 2 quadrant symbols,

this is labeled RQRCT.

LLQRCT (Right Clock Track for Lower Left Quadrant)

: Only for 4 quadrant symbols, this is the grade

based on the clock track segment to the right of the lower left quadrant.

LRQRCT (Right Clock Track for Lower Right Quadrant)

: Only for 4 quadrant symbols, this is the grade

based on the clock track segment to the right of the lower right quadrant.
