RIGOL Chapter 1 Quick Start
1-24 DS4000E User’s Guide
example, represents triggering on the rising edge in “Edge Trigger”.
Trigger Source
Display the trigger source (CH1 to CH4, EXT, EXT/5 or AC Line) currently
selected. Different label is displayed when different trigger source is
selected and the color of the parameters in the trigger setting information
corresponds to the trigger source currently selected. For example,
denotes that CH1 is selected as the trigger source.
Trigger Level
― When the trigger source is CH1 to CH4, the trigger level value is
displayed and the trigger level label
is displayed at the right of the
screen.
Note: For runt trigger and slope trigger, you need to set the trigger
level upper limit and trigger level lower limit. The difference between
the current upper limit and lower limit of the trigger level is displayed in
the trigger setting information and two trigger level labels (
and )
are displayed at the right of the screen.
― When the trigger source is EXT or EXT/5, the trigger level value is
displayed and there is no trigger level label.
― When the trigger source is AC line, there is no trigger level.
― You can use TRIGGER
LEVEL to adjsut the trigger level.
10. CH1 Status Label
Display the on/off status of CH1. When it is on, the status label is
highlighted.
Display the vertical scale of CH1 (namely the voltage value per grid of the
CH1 waveform in the vertical direction). You can use VIRTICAL
SCALE
under CH1 to modify this parameter.
Different labels may be displayed according to the current channel setting.
For example,
is displayed when the channel coupling (refer to “To
Specify the Channel Coupling”) is AC;
is displayed when the
bandwidth limit (refer to “To Specify the Bandwidth Limit”) is enabled;
is displayed when the input impedance (refer to “To Specify the Input
Impedance”) is 50 Ω.
11. CH2 Status Label
Display the on/off status of CH2. When it is on, the status label is
highlighted.
