IkaScope trigger

Triggering is one of the most important features on an oscilloscope. It allows you to select and stabilize the measurement on the useful part of a signal.

IkaScope’s triggers contain all necessary settings for edge trigger operations as shown below. You can easily define on which trigger event you want IkaScope to capture the signal.

Trigger modes

Three common trigger modes can be used (Auto, Normal and Single shot). In every case, you’ll have to set up the trigger level, by dragging the T cursor and set it to an appropriate level.

Auto

This mode always displays some signals on the screen. It is the best option when you don’t know exactly the signal you are probing. IkaScope will either:

  • Stream the data directly without synchronization (without triggering)
  • Synchronize the display to the signal if there is a trigger event, i.e. the signal is crossing the trigger level

Auto trigger mode

Normal

In this setting data will be refreshed on the screen only if a trigger event occurs.

Single shot

As its name implies, this mode will allow only one trigger event to be captured. It is used when you want to isolate a “one-shot” event and analyze it. To get another shot, just release and press again ProbeClick??? tip.

Trigger edge polarity

Three different edge types can be selected:

  1. Low to high edge
  2. High to low edge
  3. Either low to high or high to low

Trigger Hold off

Hold off option sets the period of time where the trigger is inhibited after a trig event. Set it to the minimum delay if you are not looking for a particular waveform. This setting is generally not known to beginners, yet it can be useful in certain circumstances:

  1. When multiple trigger events can occur in a very short period of time
  2. See complex waveforms with different frequencies like AM signals
  3. Trigger at a fixed rate
