WAVEFORM, VECTOR, SCH.

Using the Menus

When bezel buttons corresponding to NEXT FIELD, ALT 2 FIELD, or ALT 4 FIELD are pushed, a box flashes momentarily around the on-screen label to verify that the selection has been made.

Readout

The line select readout (in the upper left of the CRT) consists of field followed by line number. When 15H is selected, the readout also displays the range of line numbers. For exam- ple, select FIELD 1 and 15H, and rotate the LINE SEL control to line 34. This provides a readout of field 1, lines 34 through 48:

F1 34

F1 48

Line Select Functions

All of the other menus are functional during line select op- eration. The line select menu display disappears when another menu is selected, but the selected line and field are displayed until the line select menu is exited. (The field and line readout remains in the upper left of the screen, and the line select LED remains lighted to indicate this state.)

Line select can also be used with MULTIPLE displays of WAVE- FORM, VECTOR, and SCH. Selected displays appear on the screen in the following order:

The readout indicates the line number of the highest priority display. For example: with waveform and vector displays both selected, a readout of F1:20 would indicate that field 1, line 20 is displayed in waveform mode, and field 1, line 21 is displayed in vector mode.

In a waveform display, the selected line is displayed first in a two-line sweep, and brightened in a field sweep.

When line select is enabled, the rear-panel PIX MON output highlights the selected line on the picture monitor display.
