SYSTem:MINPower?
SYSTem:MINPower? yields the lower test limit of the sensor or the combination comprising the sensor
and components connected ahead of it, if the SENSe:CORRection:SPDevice parameter has the ON
value. This query can be used to determine a useful resolution for the result display near the lower test
limit.
SYSTem:RUTime[?] 0.0 to 10.0
This command is used to limit the output rate of measurements with continuous output of measurement
results (setting INITiate:CONTinuous ON). This is practical if the measurement time is very short or if
intermediate values are output (command SENSe:AVERage:TCONtrol MOVing or
SENSe:TRACe:AVERage:TCONtrol MOVing). Without this limitation, the controlling host can be
overloaded very fast or excessively occupied with accepting measured values.
The parameter in the SYSTem:RUTime command is selected so that it equals the desired minimum
interval between two measured value outputs. This is equivalent to the reciprocal of the output rate. If
the measurement takes longer to begin with, the output rate decreases proportionately.
Default setting: 0.1 [s]
SYSTem:SUTime[?] 0.0 to 10.0
This command is used to reduce the frequency of messages concerning status changes of the sensor
from the WAIT_FOR_TRIGGER state to the MEASURING state.
Normally this status change is always sent to the control unit. If measurement times are very short
and/or trigger events occur at a high frequency, however, this may lead to a heavy load on the remote-
control connection which cannot be handled by the control unit (or host). The SUTime parameter can be
used to define how long the sensor may remain in the WAIT_FOR_TRIGGER state without the
corresponding status message being output.
SUTime is usually set to a value that is slightly smaller than the response time of the control system.
Trigger events that have not yet occurred can then still be detected in time. At high trigger frequencies,
the result is that after the start of the measurement, only the first changeover to the
WAIT_FOR_TRIGGER state and the subsequent changeover to the MEASURING state are reported.
The next message would not come until the transition to the IDLE state following the completion of the
measurement.
Default setting: 0.0001 [s]
SYSTem:TRANsaction:BEGin
SYSTEM:TRANsaction:BEGin marks the beginning of a sequence of setting commands between which
the parameter limits must not be checked. This prevents the display of error messages when a setting
command causes a conflict that is resolved by a subsequent setting command. See
SYSTEM:TRANsaction:END.
SYSTem:TRANsaction:END
SYSTEM:TRANsaction:END marks the end of a sequence of setting commands between which the
parameter limits must not be checked. After this command, the parameter limits are checked.
