Reference

Display Mode: Totalize, Window, or Test

When the Analyzer is not in the Menu mode, you can select a display mode using the SELECT DISPLAY key. The display mode determines which BER and Bit Error results are shown in the main display. BER results are shown in the top, middle field of the display, while Bit Error results are shown in the top right field. Display mode also determines which results will be cleared when you press the ERROR DETECTION CLEAR key.

Procedure to Select a Results Display Mode

Press the DISPLAY SELECT key to select a different display mode. Selections are: Totalize , Window, or Test

The selected display mode will be indicated by the character in front of the BER result, as explained in the table below. Note that there are three possible Test display mode characters (T, U, and R) which further indicate which Test timing mode (Timed, Untimed, or Repeat) has been set up. Note that MODE is a parameter in the TEST Menu.
