RECORD
The RECORD command enables or disables the recording of bus data. RECORD
ON causes the Analyzer488 to begin recording bus events into the record memory.
RECORD OFF stops recording bus events.
There is an interaction between the RECORD and the SET TRIGGER
commands. If Triggering is disabled (by issuing the SET TRIGGER OFF command),
recording will begin upon receipt of the RECORD ON command and will stop upon
receipt of the RECORD OFF command.
If Triggering is enabled (by issuing the SET TRIGGER ON command),
recording will begin upon receipt of the RECORD ON command. If WHEN
COMPLETE STOP
is selected, recording will stop when match count occurrences
of match have occurred, trig delay events have occurred, and post count
events have occurred.
If WHEN COMPLETE STEP is selected, recording will remain on until the
RECORD OFF command is received. Each time the STEP command is sent, the post
count value returned by the STATUS 4 and STATUS 5 commands will be
incremented.
The query option, RECORD?, returns the string, RECORD ON, if record is
enabled or RECORD OFF if recording is disabled.
