Patterns of CH3 to CH4
H
The trigger source level is above the preset trigger level.
L
The trigger source level is below the preset trigger level.
X
Not used as a trigger source.
For the channel set as the clock channel, set the slope to (rising edge) or (falling edge), not
the pattern.
Pattern Condition
You can set the pattern condition only when a clock channel is not specified. Select
from the following:
Enter
A trigger is activated when the specified pattern of CH3 to CH4 is met.
Exit
A trigger is activated when the specified pattern of CH3 to CH4 is no longer met.
If you set the clock channel to any of the channels from CH3 to CH4, the pattern condition is set
to true.
Setting the Trigger Level, Trigger Coupling, Etc.: Level/Coupling
Set the trigger level, hysteresis, trigger coupling, and HF rejection of each channel.
For details on the trigger level, hysteresis, trigger coupling, and HF rejection, see page 6-
17 in section 6.8, “Setting the A->B(N) Trigger (ENHANCED)” in the
DL1700E Series
User’s Manual (IM701730-01E)
.
Setting the Trigger Mode
Set the conditions for updating the displayed waveforms as a trigger mode. There are
five trigger modes: auto mode, auto level mode, normal mode, single mode, and single
(N) mode.
For details on the trigger modes, see section 6.1, “Selecting the Trigger Mode” in the
DL1700E Series User’s Manual (IM701730-01E)
.
Setting the Record Length
The record length sets the amount of data to be written into the acquisition memory. The
selectable maximum record length varies depending on the model.
DL1735E/DL1740E
1 k, 10 k, 50 k, 100 k, 250 k, 500 k, 1 M (, 2 M)*
DL1740EL
1 k, 10 k, 50 k, 100 k, 250 k, 500 k, 1 M, 2 M, 4 M (, 8 M)*
*
The value inside the parentheses is selectable only when interleave mode is ON.
For details on the record length, see section 7.2, “Setting the Record Length” in the
DL1700E Series User’s Manual (IM701730-01E)
. For details on interleave mode, see
section 7.3, “Using Interleave Mode.”
Starting/Stopping the Acquisition of the I
2
C Bus Signal
When you start the acquisition of the I
2
C Bus signal, triggers are activated on the
specified trigger conditions.
To proceed to the analysis, you stop the acquisition of the I
2
C Bus signal.
