Record Complete : A dot will appear showing the Record Complete
selection in use.
Current Status : This shows the current state of the recording mechanism.
If the capture system is waiting for the trigger point, the message, "Waiting
for Trigger" will appear in the window. When the capture sequence is
complete, "Capture Sequence Completed" is displayed.
OK and Cancel: Pressing the <Return> key or clicking on these boxes will
close the capture status dialog box and return the cursor to its former
location in the active window.
5.9.3 Trigger
This command opens a dialog box that allows you to specify the
trigger parameters for recording specific IEEE 488 bus events. Use the
cursor keys or mouse to move between the various fields.
If Triggering is used, a trigger match pattern must be specified.
The Match Pattern dialog box allows you to specify the state of all
data lines and bus management lines. The state of the data lines may be
specified as an IEEE 488 bus command, a hexadecimal byte, an ASCII
character, or a binary byte. Depending on the format used, a message will
appear in the Options box specifying which entries are valid.
If Message (MSG) format is selected, the state of the data lines may
be specified as an IEEE 488 bus command (refer to the ASCII table in
Appendix H which lists IEEE 488 bus commands and their ASCII
equivalent). If not specified, 'don't care' is the default.
If Hexadecimal (HEX) format is selected, the state of the data lines
may be specified as a hexadecimal number between 00 and FF or as 'don't
care'.
If Character (CH) format is selected, the state of the data lines may
be specified as any printable ASCII character (refer to the ASCII table in
Appendix H which lists IEEE 488 bus commands and their ASCII
equivalent). If not specified, 'don't care' is the default.
