Parameters:
<Mode> LIST | GEN | STAN
LISTener: The instrument receives a time synchronization signal
at SYS SYNC IN
GENerator: The instrument provides a system synchronization
signal at the rear panel
STANdalone: The instrument uses its internal synchronization
signal
Example:
SYST:BASE:SSYN:MODE GEN
Use the R&S CMW500 to generate a system synchronization sig-
nal.

High Resolution Timer
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..................................................................................252
SYSTem:TIME:HRTimer:ABSolute:SET...........................................................................253
SYSTem:TIME:HRTimer:RELative...................................................................................253
SYSTem:TIME:HRTimer:ABSolute <Timeout>
This command starts a timer. The timeout is specified relative to an already set time-
stamp, see SYSTem:TIME:HRTimer:ABSolute:SET.
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.
