Acquiring and Displaying Waveforms

TDS 500C, TDS 600B, & TDS 700C User Manual

To bring up the Display menu:

Press DISPLAY ➞ Settings (main) ➞ Display (pop-up).

The Display menu allows you to adjust the style, intensity level, graticule, and
format features described below. The Color menu allows you to alter color
settings for various display components such as waveforms and text. To find
more information on color, see Customizing the Display Color on page 3–44.

TDS 600B only: Press DISPLAY ➞ Style  (main) ➞ Vectors, Dots, Intensified
Samples, Infinite Persistence, or Variable Persistence (side). (See Fig-
ure 3–19.)

TDS 500C and TDS 700C models only: Press DISPLAY ➞ Mode (main) ➞
Normal (pop-up) ➞ Style  (main) ➞ Vectors, Dots, Intensified Samples,
Infinite Persistence, or Variable Persistence (side)

Vectors style displays vectors (lines) between the record points.

Dots style displays waveform record points as dots.

Intensified Samples style also displays waveform record points as dots. However,
the points actually sampled are displayed in the color labeled “Zone” in the
Display Colors menus.

In addition to choosing Intensified Samples in the side menu, the oscilloscope
must be interpolating (equivalent time must be off for TDS 500C and TDS 700C
models) or Zoom must be on with its horizontal expansion greater that 1X. See
Interpolation on page 3–28; see Zooming on Waveforms on page 3–49.

Variable Persistence style accumulates the record points on screen and displays
them only for a specific time interval. In that mode, the display behaves like that
of an analog oscilloscope. You enter the time for that option with the keypad or
the general purpose knob. Record points are also displayed with colors that vary
depending on the persistence of the point. See Choose a Palette on page 3–45.

Infinite Persistence style accumulates the record points until you change some
control (such as scale factor) causing the display to be erased.
