User Interface Functionality
1. Operating state
The states are Arm, Ready, Trig’d (triggered), Stop, Auto.
2. Horizontal Timebase
Represents the time per division on the horizontal axis. Turning the horizontal scale knob (the
left knob in the Horizontal control area) changes the time per division setting from 1 ns/div to 50
s/div.
3. Trigger position parameter (delay)
Shows the time difference between a trigger point and the center of the screen. Turn clockwise
or counterclockwise to make the waveform move right or left, which will cause the delay
parameter to decrease or increase, respectively. Press the horizontal position knob to reset the
delay parameter to zero (the trigger position mark will then be in the middle of the screen).
4. Trigger position mark
Displays the trigger point on the waveform. The delay parameter is zero at this point.
5. Frequency counter
Displays the frequency of the trigger source waveform.
6. Sample rate/memory depth
Displays the current sample rate (Sa) and memory depth (Curr) of the oscilloscope. Use the
horizontal scale knob to modify the parameters.
7. Trigger settings
The trigger settings are always displayed on the upper-right side of the screen.
