*T
- Time Stamping
TYPE
System
EXECUTION
Immediate
SYNTAX
*Tstate
Specify whether or not time stamping will be enabled. Valid options for
state
are:
0
- Disable time stamping (default),
1
- Enable absolute time
stamping, and
2
- Enable relative time stamping.
DESCRIPTION
The Time Stamping (
*T
) command, when enabled, will append a time/date time stamp to each scan being sent
by the unit to the controller:
If absolute time stamping is enabled
, the format is
HH:MM:SS.MIL, MM/DD/YY
where
MIL
= milliseconds.
If relative time stamping is enabled
, the format is
±HH:MM:SS.MIL, DDDDDDD
where
MIL
= milliseconds and
DDDDDDD
= days.
In the relative mode, the time stamps are relative to the trigger scan which is time stamped
+00:00:00.000,0000000
. This implies that the pre-trigger scans are negative (-) and post trigger scans
are positive (+). Refer to the
Time Stamping
section of
Appendix C
for details.
Note:
Relative
time stamping will not be valid if you attempt to use it in conjunction with
continuous, gap-free
acquisitions
with two timebases. In addition, time stamping is not valid in burst mode.
Note: If the output format is binary instead of ASCII, the time stamp is returned as ten eight-bit bytes in 2h
(2-hexidecimal) digit format. Examples for
absolute
and
relative
time stamp formats are provided below.
Note that the 2h digit format can not be printed.
EXAMPLE
PRINT#1,"*T1X"
Enable absolute time stamping
PRINT#1,"*T2X"
Enable relative time stamping
PRINT#1,"*T0X"
Disable time stamping
