:MEASure:PERiod?
Syntax :MEAS:PER?
Form Query
Description This command is used to read the operating period of the
instrument.
In internal mode ( :TRIGger:SOURce IMMediate ) the period returned is
the internal clock period.
In external mode ( :TRIGger:SOURce EXTernal ) the period returned is
that measured at the Clock Input connector. If an invalid signal, or
no signal, is present at the Clock Input connector, a value of zero
is returned.
The query does not return a value immediately, as it waits for the
internal frequency counter to complete its next measurement cycle.
This can take about half a second.
NOTE The instrument is stopped when this command is executed. Thus,
during the measurement, no signals will be output.
NOTE When working in an automated test system, if the clock frequency
is known, it is better to set it directly instead of reading it from
the instrument. This is because:
• This method is faster since it eliminates the measurement time.
• The instrument is not stopped.
