Documentation/ISTA User's Manual of 132

◊ Source: The group of sensors. A trigger signal is transmitted to the oscilloscope via a

sensor. Possible sensors are:

◊ Probe 1 and/or 2

◊ kV clip/RVZ cable

◊ 50 A or 1000 A clip-on ammeters

Select a sensor using the arrow keys. If the sensor is not yet connected, a corresponding

message will appear.

◊ Position: With the arrow keys, you can displace the trigger time along the x-axis between

10% and 90% along the graph display. The default setting is 50%; the signal in this case is

triggered in the middle of the graph display.

◊ Level: With the arrow keys, you set the amplitude at which triggering should occur as a

percentage of the y-axis.

◊ Slope: defines whether triggering should occur on the positive or negative slope, whereby

only one switch ("pos" or "neg") can be activated at one time. If both buttons are inactive,

the trigger is activated whenever the set trigger value is reached, regardless of whether this

occurs on the rising or falling slope.

◊ Mode: Except in record mode, a trigger mode is always active. The default setting is

"Auto".

◊ Auto: If no trigger is set, then an untriggered image will be shown.

◊ Norm: Prerequisite for a display is the availability of a trigger.

◊ Single: Stops the oscilloscope measurement after the first valid trigger signal. If you

click the "Single" button again, the mode is reactivated and recording of another

measuring signal can begin.

3.4.5.2.3 Record mode

In record mode, the measurements are recorded without being triggered continuously and

temporarily stored.

Recording begins when you click the "Record" button. During recording, the latest measurements

are presented in the graph display. The remaining memory capacity is continuously displayed as a

percentage in the measurement display.

The trigger mode cannot be reactivated until the record mode has been stopped by clicking the

"Record" button.

Recording may be stopped by the following events:

◊ Repeated clicking of the Record button

◊ Reaching of the preset trigger level (depending on the trigger mode)

◊ Memory full

After completion (manual or automatic) of data recording, the "Compress" button is activated and

the entire curve along the x-axis is compressed to the width of the graph. Various tools are available

for closer examination of the curve, using cursor settings and the adjustment of values under

"Time".
