ded, or in certain time intervals. For these cases, you can define a trigger for the
measurement.
Trigger states
The sensor module has trigger states to define the exact start and stop times of a
measurement and the sequence of a measurement cycle.
The following states are defined:
●
Idle
The sensor module does not execute a measurement. After powered on, the
sensor module is in the idle state.
When a measurement has been started by one of the
INIT
commands, the
sensor module switches to the waiting for trigger state.
See
Waiting for a trigger event .
●
Waiting for trigger
The sensor module waits for a trigger event that is defined by the trigger
source, see
"Trigger sources" on page 139.
When the trigger event occurs, the sensor module enters the measuring state.
●
Measuring
The sensor module is measuring data. It remains in this state during the mea-
surement. When the measurement is completed, the sensor module either
continues with the next measurement, or finishes the current measurement
and returns to IDLE state, depending on the initial mode you have started the
measurement before.
Waiting for a trigger event
Before a trigger can be executed, you must set the sensor module to the waiting
for trigger state. Depending on whether you want to measure continuously or
want to execute one dedicated measurement, use the corresponding command:
●
INITiate:CONTinuous
on page 172
Starts a new measurement cycle automatically after the previous one has
been completed.
●
INITiate[:IMMediate]
on page 171
Starts a single measurement only. Depending on the selected measurement
function, a
single measurement can lead to an array of results, e.g., in trace
mode.

[SENSe<Sensor>:]FUNCtion
