Note

for us: These is a list of ideas for a starting an acquisition I would like to add.

  • Get to know the acquisition workflow

  • adjusting the camera configuration

  • adjusting the PowerLab configuration

  • adjusting the pacer configuration

  • other?

Example acquisition

Before you start, make sure you have initiated the setup as describe in the Starting the set-up tutorial.


Here is an schematics on how the acquisition workflows works in a regular setting:


The LabView is configured to trigger the camera on and pacer via the trigger window. There are two trigger options: the camera trigger (upper one) and the e-stimuli trigger (lower one). Turning on the trigger will send the signal to each device respectively. See bellow the example for details.


In this example the trigger will send a “free run” signal to the camera every 0.5 s (2 Hz).
Similarly, the trigger will send a signal to the e-estimulator at 2.5 Hz (every 400 ms). In orther to use this option, make sure that the pacer has been configured to mode: TRIGGERED.
Note that the pacer when operated in this way, the external e-stimuli trigger only control the frequency of the signal. Pay attention that no amplitude of the e-pacer is controlled via the LabView/PowerLab. In orther to change the voltage apmplitude of the stimuli you must set it manually on the e-pacer apparatus.

Attention!

The e-stimuli trigger does not control the amplitude (voltage) of the signal only the frequency!.


Now lets have a look at the configuration of the camera to receive the triggering signal.

If you have previously loaded a configuration file, you will find a number of macros availables as display bellow. Those are needed to facilitate the acquisiton via external triggering.

This tutoriasl is under construction. Soon will be updated.
