3.5.50 Oscilloscope function (OSZ)

3−235

EDSVS9332P−EXT DE 2.0

Function DescriptionSelectionCode

Trigger delay The trigger delay defines when to begin with the saving of the measured values with

regard to the trigger time.

C0737

−100.0 % ... 0 %

· Negative trigger delay (pre−triggering)

– Defines a percentage of the whole memory content. This part of the memory

content is filled with measured values before the triggering (see Fig. 3−183).

0 % ... 999.9 % · Positive trigger delay (post−triggering)

– Defines a percentage of the whole memory content. The saving of the measured

values after triggering is delayed by this part of the memory content (Fig. 3−182).

Sampling period C0738 1 ms ... 10 min · Setting of the sampling period

– The sampling period is the time between two measurements

– The measurements are carried out simultaneously for all channels (e. g. value

measured at channel 1 is measured at the same time as the measured value at

channel 2, 3 or 4.

– The sampling period can be set in steps of 1, 2 and 5.

Number of

Channels

C0739 Number of channels used for measurements.

Read data

memory

The code is required if the GDC is not used for the visualisation.

C0740/1 0 ... 16383 · Defines the starting point for reading the data memory and thus enables the memory

array to be selectively accessed.

– In order to read the data memory bit by bit (e. g. reading only the measured values

of one channel or reading with reduced memory depth), the starting point can be

changed.

C0740/2

1 · Enable Read memory"

– Enables the access to the memory to read the data

0 · Inhibit Read memory"

– Inhibits the access to the memory. The access must be inhibited after every

reading of the data
