HF Rejection (HF Rejection)
Select whether or not to eliminate high-frequency components (300 kHz or higher) from the trigger source.
300kHz: Eliminates high-frequency components greater than or equal to 300 kHz
OFF: Does not eliminate high-frequency components
When the broadcasting system is not set to User Define, the HF rejection setting is as follows:
NTSC, PAL, or SDTV: Fixed at 300 kHz
HDTV: Fixed at OFF
Horizontal Sync Frequency (HSync)
Set the horizontal sync frequency. Pressing the RESET key sets the frequency to 31.5 kHz.
Sync Guard Frequency (Sync Guard)

HD: High definition (tri-level sync signal)
Trigger B [B TRIG]
Trigger B is the trigger you set using the B TRIG key.
The instrument can trigger on the combination of trigger A (condition A) and trigger B (condition B).
The trigger conditions you set using the EDGE or ENHANCED key are the trigger A conditions. The trigger
conditions you set using the B TRIG key menu are the trigger B conditions.
Trigger Combination (Combination)
Set how to combine trigger A and B conditions.
• OFF: The instrument triggers only on the trigger A conditions (the trigger B conditions are not used).
• A Delay B: After the trigger A conditions are met and the specified amount of time elapses, the instrument
triggers when the trigger B conditions are met.
• A to B(N): After the trigger A conditions are met, the instrument triggers when the trigger B conditions are met
N times.
Example
A Delay B Trigger
After the trigger A conditions are met and the specified amount of time elapses, the instrument triggers when the
trigger B conditions are first met.
CH1
CH2
Condition A met
Condition B met (trigger)
1 ms
Condition A: Edge trigger, CH1 = ,
Condition B: Edge trigger, CH2 = , Delay = 1 ms
