with a frequency lower than 8 kHz.
 HF Reject: HF Reject coupling attenuates all signals with a frequency higher than
150 kHz.
4. Holdoff: Trigger holdoff can be used to stabilize a waveform. The holdoff time is
the oscilloscope's waiting period before starting a new trigger. The oscilloscope will
not trigger until the holdoff time has expired. It provides a chance for user to check
the signal in a short period and helps to check some complex signals, such as AM
waveform etc.
How to Operate the Function Menu

Peak detect
Use to capture maximal and minimal
samples. Finding highest and lowest points
over adjacent intervals. It is used for the
detection of the jamming burr and the
possibility of reducing the confusion.
