HF Rejection (HF Rejection)
Set HF rejection to 15 kHz or 20 MHz when you want to remove the high-frequency components (above 
approximately 15 kHz or 20 MHz) from the trigger signal. You can set HF rejection when the trigger 
source is a channel from CH1 to CH4.
Hysteresis (Hysteresis)
You can use hysteresis to give width to the trigger level so that the DL6000/DLM6000 does not trigger 
on small fluctuations in the signal. You can set HF rejection when the trigger source is a channel from 
CH1 to CH4.
Approximately 0.3 divisions of hysteresis around the trigger level.
*
Approximately 1 division of hysteresis around the trigger level.

*  The above values are approximate values. They are not strictly warranted.
Window Comparator (Window)
The window comparator qualifies conditions that are determined by a waveform’s rising/falling edge 
or high/low state by whether or not they fall within a given range (Window IN/OUT). It qualifies trigger 
conditions and the Qualify conditions and state conditions discussed later in this section.
You can enable or disable the window comparator separately for each channel. The trigger and state 
conditions vary as shown below depending on whether the window comparator is enabled or disabled.

The ranges and resolutions are indicated below.
Setting Range Resolution
Center ±4 divisions around the screen center 0.01 divisions
Width ±4 divisions around the center 0.02 divisions
Note
You can set the Width value to a value greater than ±4 divisions from the screen center. However, if the high 
or low level goes outside the screen, the DL6000/DLM6000 operation becomes unstable.
