• Qualified Logic Signal Pulse Width (Logic Pulse Qualified)
You can search a logic waveform. You can search for the pulse of a specified length on the
search source waveform where the logic signal waveform levels meet the specified qualifications.
You can set the search source signal to a bit from A0 to A7, B0 to B7, C0 to C7, or D0 to D7. (On
16-bit models, you can select a bit from A0 to A7 or C0 to C7.)
• Logic Signal State Condition Width (Logic Pulse State)
Y
ou can search a logic waveform. The DL6000/DLM6000 searches for points where the result of
comparing each logic signal state to the specified state condition is met or not met for a specified
period of time. If you specify a clock source, the DL6000/DLM6000 samples the comparison
results using the clock and detects the points of change in sync with the clock. For details, see
section 6.9.
Serial
Y
ou can search a serial pattern signal. The DL6000/DLM6000 searches for locations where the
data pattern of the search source waveform matches the data pattern that you have specified.
Note
When you want to search I2C, CAN, LIN, SPI, or UART signals, see the IM DLM6054-51EN option manual.
Level (Level)
Specify the level used to detect edges and conditions.
If you are setting the level for a logic signal, set the threshold level.
Taking the vertical position to be 0 divisions, you can set the level to a value within the range of ±10
divisions in 0.01-division steps. For example, when the voltage scale is 2 V/division, you can set the
threshold in 0.02 V steps.
Hysteresis (Hysteresis)
You can set the hysteresis that is applied to the level value.
You can set the hysteresis to a value from 0.0 to 4.0 divisions in 0.1-division steps.
About Qualified Logic Signal Pulse Width Searches (Logic Pulse Qualified)
Search Source Waveform (Source)
The DL6000/DLM6000 compares the pulse width of the specified bit to the specified time and
searches for locations where the conditions are met.
Y
ou can set the search source signal to a bit from A0 to A7, B0 to B7, C0 to C7, or D0 to D7. (On
16-bit models, you can select a bit from A0 to A7 or C0 to C7.)
Polarity (Polarity)
Y
ou can select which trigger source polarity will cause the DL6000/DLM6000 to compare the pulse
width to the reference times. The trigger source polarity is based on the trigger level.
Pos The signal level must be high.
Neg The signal level must be low.
Pattern
For each signal, you can set the condition that must be met for the DL6000/DLM6000 to trigger to H,
L, or X.
H The signal level must be high.
L The signal level must be low.
X No conditions have to be met (“don’t care”).
Logic (Logic)
You can set the logic for all the conditions to AND or OR.
AND The DL6000/DLM6000 triggers when all the specified conditions are met.
OR The DL6000/DLM6000 triggers when any of the specified conditions is met.
Note
You cannot specify qualifications for the trigger source signal.
