UPO2000CS series User Manua

includes DC, AC, low frequency, high frequency suppression, and noise suppression.
• DC: All of the signal
• AC: Blocks the DC component and attenuates any signal components below 10Hz.
• High frequency suppression: Attenuates high frequency components over 50kHz.
• Low frequency suppression: Blocks the DC component and attenuates low frequency components
below 5kHz.
• Noise suppression: Suppress high frequency noise in the signal, and reduces probability of error.
(4)Trigger Sensitivity
The minimum signal required to generate a correct trigger. For example, normally the input channel
(CH1~CH4) trigger sensitivity is 1div, which means the signal should be at least 1div.
(5)Pre-trigger / Delayed Trigger
Data collected before / after the event.
Trigger position is usually set at the level of the screen, and you can observe 7 grids of pre-trigger and delay
trigger information. The horizontal displacement of the wave can be adjusted by the horizontal displacement
position knob in order to observe more pre-trigger information.
(6)Forced Trigger
Press the FORCE key to generate a forced trigger signal.
If the waveform is not displayed in normal or single shot mode, press the FORCE button to collect signal
baseline to ensure acquisition is normal.
3.2 Edge Trigger
The edge can be triggered by the rising or falling edge of the signal.
Press the TRIG MENU to enter the trigger menu. Press F1 to select the trigger type, and select the trigger type
with the multipurpose knob.
The edge trigger menu descriptions are shown below:
