SetupDetectedFreqHz
SetupDetectSignals
SetupMeasuredAmpldBm
SetupMeasuredFreqHz
SetupMeasureSignals
SetupNumQuery
SetupSetDefaultAttenuation
SetupStrQuery
These setup API functions are supported only by the PhaseStation 53100A, and only
when called from within an
EventAcqSetup
handler. They are currently reserved for
internal use.
TimeHoursSinceTrigger()
TimeMinsSinceTrigger()
TimeSecsSinceTrigger()
These three functions return the elapsed time since the measurement currently
associated with the script was triggered, if the measurement is still in progress.
Otherwise, if the measurement is no longer in progress, the overall duration of the
acquisition is returned.
The values returned are floating-point Numbers that equivalently represent the elapsed
time in terms of hours, minutes or seconds.
TimeSetTimer(Number msec [, Boolean persist])
This function arranges for TimeLab to call the script’s
EventTimer()
handler at regular
intervals of
msec
milliseconds. Timer callbacks are made
msec
milliseconds after the
previous call to the timer handler returned – meaning that if a timer handler runs for
more than one service interval, missed intervals will not be made up.
Because TimeLab’s scripting system relies on cooperative multitasking, most non-trivial
scripts should carry out the majority of their processing work in their
EventTimer()
handler
while their measurement(s) are in progress. For detailed examples of timer usage, refer
to
53100A_performance_test.js and 5330A_ADC_test.js as well as
53100A_command_line_example.js and 53100A_3_cornered_hat.js .
Prior to termination, a script that uses timer service should call
TimeSetTimer(0)
to
discontinue further callbacks.
