Chapter 15 Split Display Virtual
Channel
15.1 Features
The Split Display Virtual Channel allows the display of two track,
peak or valley values from any two channels at the same time.
One value is displayed on the left side of the display, and another
value is displayed on the right side.
The display setup used to format each value is inherited from the
source channel of the value.
Split Displays are most useful on chassis with a 16-character
display such as the Models SC2000 and SC2001. The quad-line,
20-character display of the Model SC3004, however, already
allows an Input Channel to show its own Track & Peak, Track &
Valley or Peak & Valley values on the display at the same time.
Thus, a Split Display Virtual Channel is not generally used on an
Model SC3004.
15.2 Wiring
A Virtual Channel exists in software only; it does not occupy a
physical slot inside of the instrument’s chassis. However, a Virtual
Channel does require a channel number.
There is no rear-panel connector for a Virtual Channel.
