Viewing Waveforms, Vectors, and Pictures

7-24

Figure 7-25. Reduced Size Waveform Display

This display offers several choices. For example, the display can show the waveform alone, the vector

alone, or both. The background of the waveform/vector can be opaque, so you cannot see the picture

through it, or it can be mixed with the picture (see Figure 7-26). To make these choices:

1. Press the Config button.

2. Select DISPLAY and then press the Enter button.

3. Select SPLIT SCREEN and then press the Enter button.

4. Select REDUCED SIZE DISPLAY and then press the Enter button or turn the knob to select

WFM, VEC, or BOTH.

5. Select REDUCED SIZE MIX and then press the Enter button to toggle between ON and OFF.

Selecting OFF makes the display background opaque.

6. Press Clr Mnu to exit.

If Split Screen is on when making choices, you will see the changes taking place.

The graticules are simplified in this reduced size display. H and V Mag, H and V Position, Line Sel,

Vec. Phase, and Var. Gain all still function normally. You can choose between 1H and 2H sweeps, but

2F sweep is not available in reduced size images when both waveform and vector are displayed.

The picture is normally referenced to itself each time it is displayed, even if REFERENCE, EXT is

selected. This prevents the picture from shifting up and down, left and right, if the timing of the

external sync is very different from the displayed signal. To change the picture to external sync:

Press the Config button.

Select PICT. REF and then press the Enter button to select REF.

Press Clr Mnu to exit.

Now the reference for the picture follows the main reference, whether it is internal or external. The

menu line just above the reference is the same one you change when you press the Blue (2nd) button

and then the Field Sel botton. Note that when a vector is displayed with the picture, the picture

reference always goes to internal, regardless of the setting of PICT. REF.
