Measurement methods
Triggers are signals that instruct the instrument to make a measurement. You can set the 2470 to use
the following triggering measurement methods:
•
Continuous measurement: The instrument is making measurements continuously.
•
Manual trigger mode: Press the front-panel
TRIGGER
key to initiate a single measurement.
•
Trigger model: The instrument makes measurements according to the settings of the trigger
model. To select this method, a trigger model must be set up. Select
Initiate Trigger Model
to
start the trigger model, or
Abort Trigger Model
to stop a trigger model that is presently running.
Continuous measurement triggering
When you select the continuous measurement method, the instrument makes measurements
continuously.
The continuous measurement method is only available when you are controlling the instrument locally
(through the front panel).
The instrument stores the readings in the active reading buffer. See
(on page 6-1) for
detail on the buffer options that are available.
If you press the front-panel
TRIGGER
key when the instrument is set to the continuous measurement
method, measurements are not made. Instead, a dialog box is displayed that asks if you want to
change the measurement method.
