After execution of a command it may be required to wait a well defined time before pro-
ceeding with command script processing, e.g. because the DUT needs some time to
stabilize after a modification. This can be achieved using the following commands.

SYSTem:TIME:HRTimer:ABSolute
<Timeout>
This command starts a timer. The timeout is specified relative to an already set time-
stamp, see
When the timer expires, "Operation Complete" is indicated. This event can be evaluated
by polling, via a *OPC? or via *WAI.
Setting parameters:
<Timeout>
Range:
0 ms to 4294967295 ms
Default unit: ms
Example:
SYST:TIME:HRT:ABS:SET
SYST:TIME:HRT:ABS 1000
*OPC?
The three commands have the following effects:
Set a timestamp with the current system time.
Start a timer with a timeout value of 1 second relative to the time-
stamp.
Wait until the timer expires before processing the next command.
