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.

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.

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.

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.

Here is the image

Please remove D36 from the board to lower down the power comsuption of the battery.
Please try.

Removing BAT54s from board solve the problem. Else everyday i had to repalce battery

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.
