IEEE-488 Reference
3-132
3.22.8
:DATE <yr>, <mo>, <day>
:SYSTem:DATE <yr>, <mo>, <day>
Set date for clock
Parameters
<yr> = 1994 to 2093
Specify year
<mo> = 1 to 12
Specify month
<day> = 1 to 31
Specify day
Query
:DATE?
Query the date
Description
This command is used to set the date for the real-time clock. Setting an invalid date (i.e. Febru-
ary 30, 1995) result in an error and the previous date is retained.
3.22.9
:TIME <hr>, <min>, <sec>
:SYSTem:TIME <hr>, <min>, <sec>
Set time for clock
Parameters
<hr> = 0 to 23
Specify hour (24 hr format)
<min> = 0 to 59
Specify minute
<sec> = 0.00 to 59.99
Specify second (rounded to 1/100 sec.)
Query
:TIME?
Query the time
Description
This command is used to set the time for the real-time clock. Note that the time must be set using
the 24-hour format (i.e. hour 13 is 1PM). Setting an invalid time results in an error and the pre-
vious time is retained.
:TIME? returns the time to the nearest hundredth of a second.
3.22.10 :TSTamp commands
The following commands are used to configure and control the timestamp. For more informa-
tion on timestamp, see paragraphs 3.16 (:FORMat:ELEMents) and 3.23.7 (:TRACe:TSTamp
:FORMat).
:TYPE <name>
:SYSTem:TSTamp:TYPE <name>
Select timestamp type
Parameters
<name> = RELative
Select relative-time timestamp
RTClock
Select real-time timestamp
Query
:TYPE? Query
timestamp type
Description
This command is used to select the timestamp type. RTClock selects the real-time clock times-
tamp. Readings are reference to the date and time. RTClock is a 100 year (max) calendar with
10msec resolution.
RELative selects the relative-time timestamp. Readings are referenced (in seconds) to a timer.
The timer starts at zero seconds when the instrument is turned on or when the timestamp is reset
(see next command). RELative is a 55 day (max) clock with 1usec resolution.
