GPIB-410 User Manual
•
no
(do not send EOI)
Selecting
yes
causes the GPIB-410 to send EOI with the last byte in
the pattern buffer during execution of the final pass through the buffer.
Selecting
no
disables the sending of EOI.
Pattern Buffer Source
Use this field to specify the source of the 16-bit pattern sequence to be
output during execution of the Pattern Generator. The pattern buffer
containing the sequence is created and loaded from the specified source
when you type <Alt-G>. There are two options.
•
COMMAND FILE
•
INPUT WINDOW
Each of the above options is described in the following paragraphs.
•
COMMAND FILE
This option causes the GPIB-410 to use commands in a previously
prepared file on disk to construct the patterns in the pattern buffer.
The commands in the file are written in the National Instruments
Interface Bus Pattern Generating Language (IBPGL), which is
described in detail in Appendix E.
Use the associated sub-field to enter the command file pathname.
•
INPUT WINDOW
This option causes the GPIB-410 to combine the bytes of the input
window sub-field with the Monitor window switch settings to
construct the patterns in the pattern buffer. When you enable the
Pattern Generator, the input window contents are output to the GPIB
(using the source handshake) as either data or commands,
depending on the state of the Monitor ATN switch.
You can enter up to 75 characters or other byte values in the input
window. Use the following escape sequences to specify non-ASCII
or non-printable codes within the string.
