Basic Trigger Settings
• Trigger source: The trigger source signal.
• Trigger slope: Specifies which edge, rising or falling, the instrument will trigger on.
• Trigger level: The trigger determination level.
• Trigger position: The position where the trigger point will be displayed.
• Trigger delay: The delay from the trigger point.
• Trigger hold-off: The amount of time to hold off the next trigger detection.
• HF rejection: For rejecting high-frequency components in the trigger source.
• Noise rejection: The trigger level margin (the instrument does not trigger on changes in the signal level within
this margin).
Edge Trigger [EDGE]
The instrument triggers on trigger source edges (rising or falling edges). A change in the waveform that causes it
to pass through a trigger level is called an edge.
The instrument triggers here when
the trigger edge is set to rising ( ).
Trigger source
Trigger Source (Source)
Trigger source refers to the signal used to determine whether the specified trigger conditions are met. Select
from the following.
CH1 to CH4
A signal that is received through front-panel input terminals 1 to 4 (the number of input terminals varies
depending on the model).
LOGIC (On models with the logic signal input port)
A signal that is received through a front-panel LOGIC signal input port.
A signal received through a LOGIC input signal port is sampled at 1.25 GHz internally and used as a trigger
source.
You need to select the source bit (Bit0 to Bit7).
EXT (external trigger signal)
The external signal that is received through the rear-panel TRIG IN terminal.
LINE (the instrument’s power source)
The instrument only triggers on the rising edge.
The settings that you need to configure vary depending on the selected trigger source as follows:
CH1 to CH4 LOGIC (Bit0 to Bit7) EXT LINE
Slope Yes Yes Yes −
HF Rejection Yes − − −
