Start/stop recording

Proceed as follows to start a recording:

  • If you want to use the settings from an earlier recording again, open the file in which these settings are saved.
    Save the settings
  • Select the channels.
    Channel Selection, Hide/Save Channels
  • Set the trigger condition.
    Trigger
  • Start recording with the Recording > Start command.
  • After some data has been recorded, simply optimize the graph with the Scaling > Optimize Graph command. This saves you from having to manually scale each channel.
  • The Recording > Stop command interrupts the current recording or the transfer of the buffer to the control.
  • The Recording > Pause command pauses the current recording without terminating the connection. In this state all incoming data are discarded, and no trigger conditions are evaluated. Please note that in this case the time axis doesn't show the correct time any more. These breaks are marked with two short vertical lines.

The status line shows the current operating mode during recording.

At the beginning of the recording, the graph is adjusted to the buffer size.

You can stretch the time axis during recording with the zoom command. However, you cannot scroll into the past.

During the recording, the starting point is the zero point of the time axis. After the trigger condition is fulfilled, the trigger point becomes the zero point of the time axis, meaning that the pretrigger period becomes negative.

The zero point of the time axis, i.e., the trigger point, is shown in the graph as a vertical dashed line.

The cursor is always positioned at the end of the active channel while recording.

In order to view or measure a curve while recording, press the CTRL key. This freezes the screen output, and the cursor can be positioned freely.

 
Tip

Gaps in the data flow can result if data from the transmit buffer cannot be transmitted to the control in time. The transmission protocol detects these gaps, and replaces them with invalid measured values marked gray. This can be caused by an overloaded control or if the Ethernet connection is too slow.
