Functional Overview

Display Formats

The normal display format for the Generator and Analyzer are explained below. Note that the "normal" format is simply the format of the display when not in the menu mode.

Generator (Tx) Display

The Generator has a two-line by 24-character high-contrast liquid crystal display (LCD). The Generator display in its normal (non-menu) mode is illustrated in the figure below.

Figure 2-7. Generator Display in Its Normal (Non-menu) Mode

The function of each field in the normal Generator display format—that is the format used when the Generator is not in the menu mode - is described below:

The top left section of the Generator display is used to show the current frequency of the internal clock in MHz. For example a display of

6 2 2 . 0 5 0 indicates a frequency of 622.050 MHz.

The top middle section normally shows the current test pattern. For example

PN23 INV indicates that the current pattern is an inverted 223-1 PRBS.

The top right section of the display shows the amplitude of the CLOCK or DATA output, depending on which output control (CLOCK or DATA) is selected.

The bottom left section of the Generator display may show either the presently selected word memory (WORD 0 ... WORD 7) or the selected frequency memory (FREQ 0 ... FREQ 9).

The bottom middle section of the display shows the currently selected Generator error inject mode.

The bottom right section of the Generator display will normally show the baseline offset of the CLOCK or DATA output, depending on which output control (CLOCK or DATA) is selected.
