If the continuous measurement mode is switched off by means of the
INITiate:CONTinuous OFF
command, single measurements can be started with the
INITiate:IMMediate
command (see below).
After triggering and completion of the measurement, the sensor enters the
IDLE
state and remains in
this state until a new measurement is started with the
INITiate:IMMediate
command.
The query yields
•
1
for
OFF
,
•
2
for
ON
.
Default setting:
OFF
INITiate:IMMediate
INITiate:IMMediate
starts a single measurement cycle. The sensor first changes from the
IDLE
state to
the
WAIT_FOR_TRIGGER
state and begins the measurement as soon as the trigger condition is
fulfilled. Depending on the number of trigger events that are required, e.g. for averaging, the
WAIT_FOR_TRIGGER
state can be entered several times. Once the entire measurement is completed,
a measurement result is available and the sensor enters the
IDLE
state again. The
INITiate:IMMediate
command should only be used after the continuous measurement mode has been switched off with the
INITiate:CONTinuous OFF command
.
TRIGger:ATRigger:STATe[?] OFF | ON
TRIGger:ATRigger:STATe ON
generates an artificial trigger if more than 300 ms have elapsed after the
start of measurement and no trigger event has been recorded. The command is only evaluated in the
Trace
mode and, irrespective of the set averaging factor, only one trace will be recorded.
TRIGger:ATRigger:STATe OFF
deactivates the automatic trigger function.
The query yields
•
1
for
OFF
,
•
2
for
ON
.
Default setting:
OFF
TRIGger:COUNt[?] 1 to 2

This setting is designed for applications in which several consecutive measurements have to be
performed by sending the
INITiate:IMMediate
command only once, e.g. to obtain a higher measurement
speed. The gap between a single measurement and the continuous measurement mode is thus closed.
The number of measurements is defined with the parameter associated with the
TRIGger:COUNt
command. This number equals the number of results yielded by the sensor at the end of the
measurement. A measurement result can contain several numeric results, e.g. power values for the
points of a trace.
The
TRIGger:COUNt
command does not define the number of trigger events required for
performing the entire measurement task. The number is either identical or a whole-
number multiple, if averaging was activated.
A further increase in the measurement speed can be obtained by combining the mode
used with the buffered mode. The results are not made available immediately but as a
block at the end of the measurement sequence (see group commands
SENSe:POWer:AVG:BUFFer).
