Description
<name> = EOTest
BUSY
:MODE?
This command controls the operation of Digital I/O line 4 to act as either an
End-of-Test or Busy signal in the 3-bit output mode. EOT is not automati-
cally controlled in 4-bit mode. See :BSIZe below. Likewise, with BUSY
enabled in the 4-bit mode, the unit behaves if it were in 3-bit mode by ignor-
ing all attempts to drive Digital I/O line 4.
<b> = 1
0
:BSTate?
This command sets the polarity of the EOT or BUSY signal in the 3-bit
mode.
<n> = 3
4
16
:BSIZe?
This command sets the Digital I/O bit size to 3 or 4. In the 3-bit mode, Dig-
ital I/O line 4 becomes EOT, /EOT, BUSY, or /BUSY based on the
SOUR2:TTL4:MODE and SOUR2:TTL4:BST commands above. In 4-bit
mode, Digital I/O line 4 is controlled manually if SOUR2:TTL4:MODE is
set to EOT. If SOUR2:TTL4:MODE is set to BUSY, operation is identical to
the 3-bit mode. The 16-bit size is available with the 2499-DIGIO option
connected to the Digital I/O port.
This command is not affected by *RST, :SYSTem:PRESet, or *RCL.
This action command is used to immediately restore the digital output lines
to the output pattern defined by the :TTL:LEVel command.
