Tx Clocking:
Use the  arrow keys to select Clk Source or SCT Ref. Press [ENT].
Option
Clk Source Use the  arrow keys to select SCT or Tx-Terr. Press [ENT].
SCT Ref Use the  arrow keys to select Reference, DataSrcSync, or LoopTiming. Press [ENT].
(CONFIG:) Tx  Misc
Tx Misc: Clk/DataPhase
Use the arrow keys to select Clk/DataPhase or BitOrdering. Press [ENT].
(CONFIG:) Tx  Misc  Clk/DataPhase
Tx Clock Phase: Normal
Data Phase: Normal
Use the arrow keys to select Tx Clock Phase or Data Phase. Press [ENT]. For
either, use the  arrow keys to select Normal or Invert. Press [ENT].
(CONFIG:) Tx  Misc  BitOrdering
BPSK Bit Ordering: Standard
Use the arrow keys to select BPSK Bit Ordering (for BSPK compatibility) as
Standard or Non-Standard. Press [ENT].
Front Panel Operation
CLK Source: SCT
SCT Ref: Reference
SCT (Send Clock Timing) – Select as an output to provide a clock reference for the user.
•
Tx-Terr – Provides transmit clock input on the selected data interface.
•
Reference – SCT will be generated from the modem's 10 MHz reference (this could be
•
derived from and external reference if selected).
DataSRCSync (Data Source Synchronization) – No clock is provided on the interface and a
•
clock is generated such that it is phase locked to the incoming data stream.
LoopTiming – The clock generated from the received carrier is used as a reference for
•
generating SCT.
