o enable: Enable (true) or disable (false) the specified bit generator clock. If not specified,
the enable state shall remain unchanged. If the specified enable state is not “true” or
“false” the following error message shall be displayed: “Enable must be true or false”
o SLOT: Slot number of the 4391A output card for which a bit generator clock is to be
configured. SLOT must be an integer between 1 and 6.
o CLOCK: Bit generator clock number to which the command shall apply. CLOCK must
be 1 or 2. If not specified, the command shall apply to both clocks.
To set the Clock parameters use the bitcode_clock command and specify the bitrate (1 –
8000000), the delay (+/- 0.5 seconds), the slot # (1-6), and the clock number (1 or 2). Users can
enable/disable the clock using the --enable 0 (off) or 1 (on).
The following example sets the bitrate for clock 2 on Slot 5 to 4000000.
ATS-6501>bitcode_clock --bitrate 4000000 --delay 0 --enable 1 5 2
To verify the settings use the settings hardware:slots:N:tsc4391:clocks
command (where N=Slot
#) to obtain the current clock settings for the 4391 card.

Memory Block: This command shall assign a memory block to one of the 4 8-megabit memory
blocks of a 4391A output card. The application software will manage the file I/O, download,
firmware validation, and retry (if necessary). To set the card parameters use the
bitcode_memblock command and specify the file (or no file), and the format, and the bitcount.
Enabling or disabling a port on a 4391A output card is a separate function from enabling or
disabling the bit generation on the 4391A card. When a port on a 4391A output card is disabled
or when all outputs are globally disabled, the output signal of the port is electrically isolated from
the bit generator output and is set to a constant zero value. When a port on a 4391A output card
is enabled, the output reflects the current value of the assigned data source. Bit generation is
enabled and disabled by enabling or disabling the code stream engines. When changing the
parameters of an enabled bit generator clock, the software shall disable the clock, make the
specified changes, and re-enable the clock when appropriate. Memory block download may
occur only if the block is not associated with enabled code generator stream.
