Freq Offset
Pointer Action
Burst Count
The Pointer Frequency Offset function adjusts the rate at
which Pointer adjustments are needed in the payload.
This type of adjustment simulates network clocks that either
run fast or slow. By adjusting the frequency offset rate, this
forces the network equipment to compensate by
decrementing or incrementing the Pointer bytes.
Entering a positive Frequency Offset causes the Pointer
Value to decrement. This is known as negative frequency
justification.
Entering a negative Frequency Offset causes the Pointer
Value to increment. This is known as positive frequency
justification.
The Pointer Frequency Offset function uses a keypad to
enter a frequency offset ranging from -100.0 ppm to +100.0
ppm.
Entering higher positive or lower negative numbers
increases the frequency justification rate.
This function is disabled by entering 0 for the frequency
offset.
