Trigger Level Knob help information

Trigger level determines where on the edge the trigger point occurs.

Turn the trigger level knob to stabilize a repeating signal, or to trigger on a single event.

Push this knob to set the trigger level to the midpoint of the waveform.

The trigger level position is indicated by the yellow arrow on the left side of the display.

Horizontal Controls

To adjust the horizontal (time/div) scale

To adjust the horizontal delay (position)

Panning and Zooming Single or Stopped Acquisitions

To display the zoomed time base

Horizontal expand

The horizontal controls include:

? The horizontal scale and position knobs.

? The zoom key (push horizontal scale knob) for quickly enabling/disabling the split-screen zoom display.

To adjust the horizontal (time/div) scale

1 Turn the large horizontal scale (sweep speed) knob marked           to change the horizontal time/div setting.

While you change the time/div (horizontal time base), the displayed waveforms of all channels are expanded or

compressed horizontally relative to the current selected horizontal expansion reference position (refer to "Horizontal

Expansion").

Notice how the time/div information in the status line changes.

The horizontal scale knob works (in the Normal time mode) while acquisitions are running or when they are stopped.

When running, adjusting the horizontal scale knob changes the sample rate. When stopped, adjusting the horizontal

scale knob lets you zoom into acquired data.

Note that the horizontal scale knob has a different purpose in the Zoom display.

To adjust the horizontal delay (position)

Horizontal position, also called trigger position, refers to the trigger point position of the waveforms of all channels

in the horizontal direction relative to the screen center. When the waveform trigger point is at the left (right) side of

the screen center, the horizontal position is a positive (negative) value.

While you change the horizontal position, the waveform  trigger points (solid inverted triangle)   and the displayed

waveforms of all channels are moved left and right.

WisdomAugust

Turn the horizontal delay (position) knob ().

The trigger point moves horizontally, pausing at 0.00 s (mimicking a mechanical detent), and the delay value

is displayed in the status line.

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

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

Everything to the right of the trigger point is called post-trigger information. The amount of delay range (pre-trigger

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

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

When running, adjusting the horizontal scale knob changes the sample rate. When stopped, adjusting the horizontal

scale knob lets you zoom into acquired data.

Note that the horizontal position knob has a different purpose in the Zoom display.

Panning and Zooming Single or Stopped Acquisitions

When the oscilloscope is stopped, use the horizontal scale and position knobs to pan and zoom your waveform.

The stopped display may contain several acquisitions worth of information, but only the last acquisition is available

for pan and zoom.

The ability to pan (move horizontally) and scale (expand or compress horizontally) an acquired waveform is important

because of the additional insight it can reveal about the captured waveform. This additional insight is often gained from

seeing the waveform at different levels of abstraction. You may want to view both the big picture and the specific little

picture details.

The ability to examine waveform detail after the waveform has been acquired is a benefit generally associated with digital

oscilloscopes. Often this is simply the ability to freeze the display for the purpose of measuring with cursors or printing the

screen. Some digital oscilloscopes go one step further by including the ability to further examine the signal details after

acquiring them by panning through the waveform and changing the horizontal scale.

There is no limit imposed on the scaling ratio between the time/div used to acquire the data and the time/div used to view

the data. There is, however, a useful limit. This useful limit is somewhat a function of the signal you are analyzing.

To display the zoomed time base

Zoom, formerly called Delayed sweep mode, is a horizontally expanded version of the normal display.

When Zoom is selected, the display divides in half. The top half of the display shows the normal time/div

window and the bottom half displays a faster Zoom time/div window.

The Zoom window is a magnified portion of the normal time/div window. You can use Zoom to locate and

horizontally expand part of the normal window for a more detailed (higher-resolution) analysis of signals.

To turn on (or off) Zoom:

1 Press the zoom key ( press the Horiz scale knob         ).

WisdomAugust

The area of the normal display that is expanded is outlined with a box and the rest of the normal display is ghosted.

The box shows the portion of the normal sweep that is expanded in the lower half.

To change the time/div for the Zoom window, turn the horizontal scale (sweep speed) knob. The Horizontal scale

(sweep speed) knob controls the size of the box. Compared with the time/div of normal window, the time/div for the

Zoom window has increased the waveform  resolution.

The Horizontal position (delay time) knob sets the left-to-right position of the zoom window.

To change the time/div of the normal window, turn off Zoom; then, turn the horizontal scale (sweep speed) knob.

Note: The time/div of the zoomed window should be smaller than or equal to the time/div of the normal window.

Horizontal Expansion

Horizontal expansion indicates the reference position that the screen waveform is referenced to when it is horizontally

expanded or contacted in adjusting the Horizontal SCALE knob. In YT mode, press Acquire-> Horiz Expand to select

the desired reference position. The horizontal expansion reference supported by the oscilloscope includes Screen Center,

Trigger Point.

The default is "Screen Center".

* Screen Center: when the time/div ( horizontal time base) is modified, the waveform will be expanded or contracted

horizontally relative to the center of the display.

* Trigger Point: when the time/div ( horizontal time base) is modified, the waveform will be expanded or contracted

horizontally relative to the trigger point.

Note: This function is unavailable in YT mode with the delayed sweep being enabled
