:TSTamp commands
The following commands are used to configure and control the timestamp. For more informa-
tion on timestamp, see paragraphs 3.14 (:FORMat:ELEMents) and 3.22.7 (:TRACe:TSTamp
:FORMat).
:TYPE <name>
:SYSTem:TSTamp:TYPE <name>
Select timestamp type
<name> = RELative
Select relative-time timestamp
1
RTClock
Select real-time timestamp
2
1
RELative is a 55 day (max.) clock at a 1µs resolution.
2
RTCLock is a 100 year (max.) calendar at a 10ms resolution.
:TYPE?
Query timestamp type
This command is used to select the timestamp type. RTClock selects the real-time clock time-
stamp. Readings are reference to the date and time. RELative selects the relative-time time-
stamp. 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).
PRINT #1, "output 16; :syst:tst:type rtc; type?"
' Select RTClock and query
PRINT #1, "enter 16"
' Get response message from
2002
:RELative:RESet
:SYSTem:TSTamp:RELative:RESet
Reset relative timestamp to 0.
This action command is used to reset the relative-time timestamp to zero seconds.
PRINT #1, "output 16; :syst:tst:rel:res"
' Reset relative timestamp
:RNUMber:RESet
:SYSTem:RNUMber:RESet
Reset reading number to zero
When the reading number is included as a GPIB data element (see paragraph 3.14; :FOR-
MAT:ELEMents), each reading sent over the bus is assigned a number starting at #0. The read-
ing number resets to zero when the instrument is turned on or when this action command is
asserted.
PRINT #1, "output 16; "syst:rnum:res"
' Reset reading number
