FFT
The FFT key activates and deactivates a Fast Fourier Transformation (FFT) for the
most recently selected channel and provides functions to configure and display FFTs.
If activated, the FFT key lights up. Two windows are displayed: the signal vs. time win-
dow at the top, and the result window of the FFT analysis at the bottom.
When deactivated, the previous display is restored.
To display the FFT for a different channel, press the corresponding channel key.
3.1.5 TRIGGER Controls
The keys and the rotary knob in the TRIGGER functional block adjust the trigger and
start or stop acquisition.
RUN CONT
Starts and stops the continuous acquisition. A green light indicates a running acquisi-
tion. A red light shows that acquisition is stopped.
The status is shown also at the right end of the information bar: "Run" or "Complete".
RUN Nx SINGLE
Starts a defined number of acquisitions. Press the key again to stop running acquisi-
tions.
To set the number of acquisitions, press the ACQUISITION key and enter "Nx Single".
FORCE
If the acquisition is running in normal mode and no valid trigger occurs, forcing the trig-
ger provokes an immediate single acquisition. Thus you can confirm that a signal is
available and use the waveform display to determine how to trigger on it.
MODE
Toggles the trigger mode between Auto and Normal. The trigger mode determines the
behavior of the instrument if no trigger occurs. The current setting is shown in the infor-
mation bar.
