Operation
KJM6335
When SYMMETRY mode is set to MANUAL, the slice level
needs to be set manually. Follow the procedures given below.
1.
Pressing the SYMMETRY key with the SHIFT key held
down. The meter will indicate a slice level until the keys are
released.
2.
Turn the SYMMETRY LEVEL variable resistor to set the
slice level required. The meter's 0 % indication shows about 0
% slice level with respect to the full amplitude of an input
signal, while 10 % (20 %) indication shows 100 % slice level.
Since the internal circuit is AC coupling, the actual slice level
changes with the duty ratio of an RF input signal. Set the
optimal slice level according to the duty ratio of the input
signal. For detail, see 3.7 "Symmetry and Slice Level".
3.
The meter indicates the measured value when you release
your hand from the SHIFT key and the SYMMETRY key.
When DELAY mode is set to AUTO, delay time is automatically
adjusted so that the average phase difference between the RF and
clock signals becomes 180
˚
. Use the instrument with DELAY set
to MANUAL, if AUTO mode is not suitable, as with cases in
which the jitter distribution has two frequency peaks.
When DELAY mode is set to MANUAL, turn the DELAY TIME
variable resistor for optimum phase difference by observing the
PHASE MONITOR. For detail, see 3.8 "Adjusting Delay".
