Horizontal

Scale Knob

Sets the timebase (horizontal sweep speed) in units

of one division per indicated time unit. Press the

knob to enter Zoom mode.

Horizontal Scale Knob

Turn the Horizontal Scale knob to adjust the horizontal time base. Turn clockwise to reduce the

time per division and counterclockwise to increase.

The time base information at the upper left corner of the screen will change accordingly during

the adjustment. The range of the horizontal scale is from 1 ns/div to 50 s/div.

The Horizontal Scale knob works (in the Normal time mode) while acquisitions are running or

when they are stopped. When in run mode, adjusting the horizontal scale knob changes the

sample rate. When stopped, adjusting the horizontal scale knob lets you zoom into the acquired

data.

Adjust Trigger Delay

Turn the Horizontal Position knob to adjust the trigger delay of the waveform. This will cause the

displayed waveforms to move left or right. The delay number at the top of the screen changes

accordingly. Press this knob to reset the trigger delay to zero.

Changing the delay time moves the trigger point (blue inverted triangle at the top of the screen)

horizontally and indicates how far it is from the time at the center of the screen.

All events displayed left of the trigger point happened before the trigger occurred. These events

are called pre-trigger information and they show the events that led up to the trigger point.

Everything to the right of the trigger point is called post-trigger information and these are events

that occurred after the trigger. The amount of delay range (pre-trigger and post-trigger

information) available depends on the time/div selected and memory depth.

The position knob works (in the Normal time mode) while acquisitions are running or when they

are stopped.

Roll mode

Press the Roll button to enter roll mode.

In Roll mode, the waveform moves slowly across the screen from right to left. It operates only on

time base settings of 50 ms/div and slower. If the current time base setting is faster than the 50

ms/div limit, it will be set to 50 ms/div when the Roll button is pressed.
