To verify the settings use the
status hardware:outputs:slots:N
command (where N=Slot #) to
obtain the current settings for a particular card.

Warning:
The user configurations for the specific output formats are stored on the system itself.
Replacement modules will automatically be configured with the correct output format as long as
the replacement card is installed in the same slot. Moving the output module to a different slot
causes the system to configure the module with the default output format(s) until that card slot is
properly configured by the user.
2.4.2.4 4391 Code Generator
The 4391 Code Generator is capable of generating user defined bit streams with a known
relationship to UTC. The code generation segment uses the local UTC estimate and a user-
generated data file and produces a bit stream (derived from the user-generated file) whose first bit
is aligned to within 1 ns of the local UTC estimate.
The user must set up the card for the proper clock, memory block, port, and stream settings for
the system to operate within the end user environment. By default the output is a 4MHz square
wave. Ports 1 and 2 are 4V 0-pk into 50
Ω
and Ports 3 and 4 are 2.8V 0-pk into 50
Ω
. All 4 ports
are in phase.
The outputs are user programmable based on the commands described below.
