LF Reject
Low-frequency reject (LF reject) adds a high-pass filter with the
3-dB point at 50 kHz. LF reject removes low-frequency signals,
such as power line noise, from the trigger path.
• Press Mode/Coupling&Coupling&LF Reject.
Noise rejection
Noise reject increases the trigger hysteresis band. By increasing
the trigger hysteresis band, you reduce the possibility of
triggering on noise. However, this also decreases the trigger
sensitivity so that a slightly larger signal is required to trigger
the oscilloscope.
• Press Mode/Coupling&HF Reject.
