4.4.2.23.2 Channel B Output
The Channel B Output option, shown in Figure 123, selects what signal appears on the Q/Video B output: Normal,
Tape Out, or Carrier Only. The Normal output depends on the selected Mode, as shown in Table 9. Tape Out
outputs the Pre-D signal, and Carrier Only outputs an unmodulated carrier; either of these will be output at the
carrier frequency selected by Tape Out Freq (MHz).

4.4.2.23.3 Channel A Scale
The Channel A Scale option, shown in Figure 124, adjusts the peak-to-peak amplitude on the I/Video A output. By
default the video output is 1.0000 V peak-to-peak using a standard deviated NTSC video signal. This setting allows
the user to compensate for a system where this is not the case.
To change the Channel A Scale setting, select the Channel A Scale option, then press the Enter key on the front
panel. A dialog scre
en displays prompting the operator to enter a new Channel A scale setting using the rack’s front
panel numeric keypad. When the new value is entered, press the Enter key on the keypad.
