To Enable the Channel
DS4000 provides four analog input channels (CH1 to CH4) and provides independent
vertical control system for each channel. As the vertical system setting methods of
the four channels are completely the same, this chapter takes CH1 as an example to
introduce the setting method of the vertical system.
Connect a signal to the channel connector of any channel (for example, CH1) and
then press CH1 in the vertical control area (VERTICAL) at the front panel to enable
CH1. At this point:
Panel:
The backlight of this key turns on. If the corresponding function has been enabled,
the character “AC”, “50” or “BW” will also be illuminated. Note that the on/off state of
the key light of “AC”, “50” or “BW” is not controlled by the on/off state of the channel.
Screen:
The channel setting menu is displayed at the right side of the screen and the channel
label at the bottom of the screen (as shown in the figure below) is highlighted. The
information displayed in the channel label is related to the current channel setting.
After the channel is turned on, modify the parameters such as the vertical scale, the
horizontal time base and the trigger mode according to the input signal to make the
waveform display easy to observe and measure.
