Noise Rejection

Noise rejection reduces the possibility of noise triggering by increasing the trigger
hysteresis.
Press MENU (in the trigger control area (TRIGGER) at the front panel)  Setting
and press Noise Reject to turn the noise rejection on or off.

Trigger Output Connector

The trigger output connector [Trig Out/Calibration] at the rear panel of the
oscilloscope can output trigger signal determined by the current trigger setting.
Trigger Output Connector
Press Utility  AuxOutput and turn the multi-function knob
to select
"TrigOut". You can also press AuxOutput continuously to switch to "TrigOut". Each
time the oscilloscope is triggered, it outputs a signal that can reflect the current
capture rate of the oscilloscope via the [Trig Out/Calibration]. Connect the signal
to a waveform display device and measure its frequency; the measurement result
should be equal to the current capture rate.
