The second option allows the transmit encoding to be preserved and output from the RDMS unaltered. To
accomplish this, PCM Encoding must be set to NRZ-L – regardless of the actual transmit encoding. Also, for
encoding formats that use di-bits to represent each user bit (i.e., RZ, Biϕ, DM, or M2), the RDMS bit rate must be
set to twice the user bit rate. Note that the RDMS output clock will clock at twice the user bit rate in this
configuration.
Select the desired encoding format from the drop down menu, as shown in Figure 55.

Channel A Video Output
The Channel A Video Output option, shown in Figure 56, selects what signal appears on the I/Video A output:
Normal, Tape Out, or Carrier Only. The Normal output depends on the selected Mode, as shown in Table 5. 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).
