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 s can 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 sc an which i s 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 i s 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 s t amp 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
