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 SPI Bus Signal Acquisition
When you start the SPI Bus signal acquisition, triggers are activated on the specified
trigger conditions.
To proceed to the analysis, you stop the SPI Bus signal acquisition.
