Set the vertical system EN next to the value box as shown in the figure below. 6.4 Channel coupling Set the coupling mode to filter out unwanted signals. Open Vertical channel > Coupling to select the coupling mode as shown in the figure below. ⚫ When the coupling mode is "DC", both DC and AC components of the measured signal can pass through. ⚫ When the coupling mode is "AC", the DC component of the measured signal is blocked. ⚫ When the coupling mode is "Grounded", the DC and AC components of the measured signal are blocked. After the coupling mode is set, the current coupling mode is displayed in the channel label, as shown in the figure below.
6.5 20M bandwidth limit This oscilloscope supports bandwidth limit. Setting bandwidth limit can reduce noise in the display waveform. For example, the signal being measured is a pulse signal with high frequency oscillations. ⚫ When the bandwidth limit is turned off, the high frequency component of the ⚫ If the bandwidth limit is turned on and restricted to 20 MHz, the high frequency measured signal can pass through. components larger than 20 MHz in the measured signal are attenuated. Open Vertical channel > BW limit and select a bandwidth limit. The default state of bandwidth limit is off.
After it is enabled, the color of B on the channel label is the same as that of the channel as shown in the figure below. Tablet1000 User manua l Copyright © Qingdao Hantek Electronics Co., LTD 28
