SYSTem:TIMeout
Syntax
SYSTem:TIMeout {<time> | MINimum | MAXimum | INFinity | DEFault}
SYSTem:TIMeout? [{MINimum | MAXimum | DEFault}]
Description
This command sets the per-measurement timeout for all measurements. If a measurement does not com-
plete before the timeout expires, 9.91E37 (Not a Number) will be returned for that measurement. The
timeout is disabled if INFinity or 9.9E37 is specified (the instrument will always wait for the measurement
to complete).
Parameters
Name Type Range of Values Default Value
<time> Numeric 9.9E+37 (disabled) or
10 msec to 2000 sec
with 1 mS resolution
MIN = 10 msec
MAX = 2000 sec
9.9E+37 (disabled)
Remarks
l When selecting a timeout value, you should include the effects of trigger delay (TRIGger:DELay), the
measurement or gate time (SENSe:FREQuency:GATE:TIME or SENSe:TOTalize:GATE:TIME), the gate
open delay (SENSe:GATE:STARt:DELay:TIME or SENSe:GATE:STARt:DELay:EVENts), and the gate close
holdoff (SENSe:GATE:STOP:HOLDoff:TIME or SENSe:GATE:STOP:HOLDoff:EVENts), as well as the input
signal frequency.
l If the timeout value is less than the gate time, or the sum of the gate open delay and close holdoff, then
a timeout value of twice the gate time, or twice twice the sum of the gate open delay and close holdoff,
will be used for the measurement. The programmed timeout value, however, will remain unchanged.
l If multiple measurements are being made (SAMPle:COUNt or TRIGger:COUNt set to greater than 1),
the timeout applies individually to each measurement.
l The timeout is stored in non-volatile memory, and does not change when power has been off, after a
Factory Reset (*RST command), or after an Instrument Preset (SYSTem:PRESet command).
l The timeout is disabled when the instrument is shipped from the factory or after a SYSTem:SECur-
ity:IMMediate command.
Return Format
The query returns the timeout in the form +2.00000000E+000. For a infinite timeout, the query returns
9.9E37.
