 Press Format to set the display format of the digital bus to Hex, Decimal, Binary
or ASCII.
 Press Jitter Reject to turn on the jitter rejection function. Jitter refers to the
short-term deviation of the signal relative to its ideal time position at certain
time point, as shown as T1 and T2 in Figure 7-1. When no reference clock is
selected for the bus, the jump status of each channel would cause the variation
of the bus data and undesired data would be generated due to jitter when the
bus data varies. When the jitter rejection is turned on, the bus does not display
the variation of the bus data caused by certain jitter time and still holds the
effective data.
 Press Jitter Time and use the multifunction knob or navigation knob to set
the jitter time and the range is from 1 ns to1 ms.
Note: Jitter rejection and jitter time can be set only when no reference clock is
selected.
