Identifying Items in the Display

The items shown to the right may appear in the display. Not all of these items are visible at any given time. Some readouts move outside the graticule area when menus are turned off.

1. The acquisition readout shows when an acquisition is running, stopped, or when acquisition preview is in effect. Icons are:

Run: Acquisitions enabled

Stop: Acquisitions not enabled

Roll: In Roll mode (40 ms per division or slower)

PreVu: In this state, the oscilloscope is stopped or between triggers.

You can change the horizontal or vertical position or scale to see approximately what the next acquisition will look like.

2. The trigger status readout shows trigger status. Status conditions are:

Trig'd: Triggered

Auto: Acquiring untriggered data

PrTrig: Acquiring pretrigger data

Trig?: Waiting for trigger

3. The trigger position icon shows where the trigger occurred in the acquisition.

4. The expansion point icon (an orange triangle) shows the point that the horizontal scale expands and compresses around.

5. The waveform record view shows the trigger location relative to the waveform record. The line color corresponds to the selected waveform color.

6. The FilterVu indicator shows if the variable low pass filter is active.

7. The cursor readout shows time, amplitude, and delta (Δ) values for each cursor.

For FFT measurements, it shows frequency and magnitude.

For serial buses, the readout shows the decoded values.

8. The trigger level icon shows the trigger level on the waveform. The icon color corresponds to the trigger source color.

9. The trigger readout shows the trigger source, slope, level, and frequency for an Edge trigger. The trigger readouts for other trigger types show other parameters.

10. The horizontal position/scale readout shows on the top line the horizontal scale

(adjust with the Horizontal Scale knob).

With Delay Mode on, the bottom line shows the time from the T symbol to the expansion point icon (adjust with the

Horizontal Position knob).

Use horizontal position to insert added delay between when the trigger occurs and when you actually capture the data.

Insert a negative time to capture more pretrigger information.

With Delay Mode off, the bottom line shows the time location of the trigger within the acquisition, as a percentage.

11. Measurement readouts show the selected measurements. You can select up to four measurements to display at one time.

A symbol appears instead of the expected numerical measurement if a vertical clipping condition exists. Part of the waveform is above or below the display. To obtain a proper numerical measurement, turn the vertical scale and position knobs to make all of the waveform appear in the display.

12. The auxiliary waveform readouts show the vertical and horizontal scale factors of the math and reference waveforms.

13. The channel readout shows the channel scale factor (per division), coupling, invert, and bandwidth status. Adjust with the Vertical Scale knob and the channel

1, 2, 3, or 4 menus.

14. For digital channels (MSO2000B series only), the baseline indicators label the channel, and point to the high and low levels. The colors follow the color code used on resistors. The D0 indicator is black, the D1 indicator is brown, the

D2 indicator is red, and so on.

The bus display shows decoded packet level information for serial buses or for parallel buses (MSO2000B series only).

The bus indicator shows the bus number and bus type.

Not shown in this illustration, the Timing

Resolution readout shows the timing resolution of the digital channels. To see the readout, push the D15-D0 front panel button.

15. For math channels, the waveform baseline indicator shows the zero-volt level of a waveform.

16. For analog channels, the waveform baseline indicator shows the zero-volt level of a waveform (ignoring the effect of offset). The icon colors correspond to the waveform colors.
